Article Research at MSUL

Articles contain the most current information published in a field of study.

Most professors and researchers prefer articles that are "scholarly" in nature.  Characteristics of scholarly journals are that they have the following qualities:

  • The articles contain original research (such as scientific experiments, surveys and research studies)
  • A list of references or sources is provided at the end of each article
  • An editorial board, composed of experts in the field, reviews articles to decide whether they should be accepted; this is also known as "refereed," "peer-reviewed," "professional," or "academic".
  • Uses a specialized vocabulary for that field.
  • Contain few if any advertisements. If included, they are highly specialized and specific to scholarly discipline (i.e. specific laboratory equipment, medical tools and drugs).
  • If you are uncertain about the scholarly nature of a journal, you all look up the title or ISSN in the periodical database Ulrichs Periodical Directory (UlrichsWeb) .  This database will tell you about the journal including the nature, it's audience, and in which databases it is indexed and abstracted.

The Library Catalog contains the TITLES to all of the print and electronic format journals to which we have access .  The Catalog does not list the articles within the journals. The individual articles can be found in the many article databases to which we subscribe.

Citation searching:

If you have a citation to an article, the easiest way to locate the article is to look up the title of the journal in the catalog .  Identify whether we own the journal and the format, print or electronic.  If in electronic format, do we have that year/volume? If yes, you can click on the link provided to go directly to the online articles and find the one you need.  If it is not online, do we have it in print?  If so, identify the call number and go to the stacks to find the proper volume and issue.  If we do not own the journal or issue, you can request the article through Interlibrary Services .

This resource is available only to Faculty, Staff, and Students logged in with their NetID.

Article databases - 2nd choices

This resource is available to all MSU and non-MSU users.

Return to Information for Authors main page JXB Data Policy

All revised papers should follow the formatting guidelines below.

1. Article Structure

The following sections list the structure that the various article types published in JXB should follow. All revised papers should follow these structures.

Research Papers

  • Introduction
  • Discussion (or Results and discussion)
  • Supplementary data (a brief, single-sentence description for each item, not the actual figures/tables or full legends)
  • Acknowledgements
  • Author contributions
  • Conflict of interest
  • Data availability
  • Figure legends and (optional) Alt text for accessibility
  • Figures, including figure legends (these should be uploaded as a separate file(s). Please find specific guidelines in the Figures section .

Reviews (Including Flowering Newsletter Reviews, Darwin Reviews and Expert Views)

  • Main text (please use headings to divide into sections)
  • Data availability (for those reviews that include meta-analysis of collated datasets)
  • Boxes (optional except for ‘key developments box’ for Expert Views)

Viewpoints and Insights

  • Highlights (For Viewpoints)
  • Introductory paragraph (please note Viewpoints and Insights do not have abstracts)
  • Boxes (optional)
  • Figure legends
  • Figures, including figure legends (these should be uploaded as a separate file(s)). Guidelines for preparing figures can be found in the Figures section below.

2. Title Page

The title page should contain the title, names of all authors, and names and addresses of the institutions where the work was carried out, and an email address for each author. The date of submission, the number of tables and figures, and the word count (start of the introduction to the start of the acknowledgements, excluding materials and methods) should be listed. If the paper has supplementary data, specify the number of figures, tables or videos.

The title should be concise and informative for a broad scientific audience, with no more than 120 characters including spaces . For research papers, the title should usually state the novel scientific findings being presented. A title that poses a question can be effective. Remember this will be the most frequently read part of your paper. Please avoid abbreviations and include species names (well-known common names are acceptable).

Also add a shorter running title of no more than 60 characters including spaces.

3. Highlight and Abstract

3.1 highlight.

Please provide a statement that, in fewer than 30 words, highlights the novelty of the paper for the non-expert. The highlight should contain the central findings of your work, as well as keywords and phrases, but should not simply repeat the title. For reviews, the highlight should state the primary objective of the review.

Highlights are used in table of content alerts online and via emails, as well as on the advance access page, so they are a useful way to attract readers to your paper..

3.2 Abstract

The abstract should be an engaging and informative 'stand-alone' text (without references) of no more than 200 words. Abstracts for research papers should detail why the research was undertaken; the approach and methodology if appropriate; the main findings; and the key conclusions, including wider implications. Repeat keywords and phrases as appropriate. Abbreviations should only be defined and used within the abstract if they are used three times or more in the abstract itself.

For reviews, abstracts should state the primary objective of the review and the reasoning for focusing on this objective, the principal findings of the review, and any conclusions that might be drawn from it, including implications for further research or practices.

JXB welcomes the inclusion of graphical abstracts with submissions. These will be published in the html and pdf version of published papers. When preparing your graphical abstract, please refer to the journal’s Figure preparation guidance .

4. Keywords and Abbreviations

4.1 keywords.

Please list 6–10 keywords (in alphabetical order) after the abstract. Think of words people might use in searches. The main keywords should also appear in the title, abstract, highlight, and subheadings. Natural, consistent repetition of keywords will aid search engine optimisation so others can more easily find and cite the paper.

4.2 Abbreviations

Please limit the use of non-standard abbreviations, which can make the text harder to read. Generally, only use them for words mentioned more than three times in the text but only where the shortened form will aid readability. Spell out the term on first mention: for example, ‘the International Rice Research Institute (IRRI) is developing rice varieties…’. If you do have such defined abbreviations, also list them , in alphabetical order, after the keywords.

There are a number of common abbreviations that may be used without definition. The same applies to standard chemical symbols.

Authors are asked to avoid using 'CK' as an abbreviation for 'control' as this abbreviation is more commonly used for 'cytokinin' within plant sciences.

5. Materials and methods

This section should provide a detailed and complete description of the materials and methods adopted in the study. The description should provide sufficient detail to enable the reader to both understand and replicate the experiments performed. If commercial kits or an external service provider are used for sample analysis, the basic principle underlying the measurements or analysis should be described as well as the commercial source or service provider (e.g., "IAA was measured using an ELISA-based kit (Biological Analytics Ltd., Oxford , UK; www.biologicalanalytics.com)". Published articles may be cited instead of giving a full description, as long as authors verify that the cited article contains a reasonably complete description of the respective materials and/or method. Any deviations from the previously published method that could significantly change the outcome of the experiment must be detailed in full. Methods essential to understanding and replicating experiments should not be included in the supplementary data. The inclusion of previously unpublished primary experimental data is not permitted in all types of JXB reviews, and as such, review manuscripts should not contain a materials and methods section.

To facilitate the reproducibility of studies, authors submitting to JXB are encouraged to consider depositing novel protocols to a suitable public repository, such as protocols.io or Zenodo . Similarly, authors whose papers include code should consider uploading their code to a public repository such as GitHub . For authors submitting Technical Innovations and Community Resources that introduce new methods and tools, depositing protocols into an appropriate repository is a pre-submission requirement. Once authors have described the step-by-step protocol on their selected repository, a DOI will be issued. The DOI should be cited in the materials and methods section, enabling editors and reviewers to access the protocol. Authors can choose for their method to be kept private until their paper is published but access to editors and reviewers should be provided where possible, for example, by obtaining a shareable link for the protocol to be accessed before it is published. As well as being searchable and citable, protocols deposited in protocols.io are presented in a clear, formatted form, and new versions can be included as methodologies develop over time. Authors should not simply copy and paste all the text from within their materials and methods section when depositing in a repository.

Authors should divide the materials and methods into appropriate sections and should refer to the Styling Points section of this guide for information on reporting numbers and dates, scientific names, units of measurements ( SI units ), chemicals, genes and proteins, and equations.

The materials and methods section should include a subsection called ‘Statistical Analysis’ providing details of replication and statistical analysis used within the study.

Authors should state the exact sample size (n) for each experimental group. A description of sample collection, including a statement on whether measurements were taken from distinct samples (biological replicates) or whether the same sample was repeatedly measured ( technical replicates ) should be provided, as well as whether a paired or unpaired study design was followed. Information and advice on replication in plant experiments is available in Rogers et al. (2021) (https://doi.org/10.1093/jxb/erab268). Statistical tests used must be appropriate to the type of data and a description of any assumptions or corrections, such as tests of normality and adjustment for multiple comparisons should be provided. Details of the statistical methods used should be listed; common tests (t-test, simple χ2 tests, Wilcoxon, Mann–Whitney tests and one-way and two-way ANOVA) and common post-hoc tests can be identified by name, but more complex techniques must be detailed in full (e.g., multiple linear or nonlinear regression models, multiple logistic regression models). Any software used for statistical analysis should be identified, together with the version used.

It is expected that novel materials used and described in new papers be made available for non-commercial research purposes upon publication. A statement concerning availability, or restrictions on availability, should be included in the data availability section. It is acknowledged that some materials such as enzymes, natural products, and antibodies require substantial effort to generate, and supplies may be limited—a judgement will be made on whether any restrictions on availability are reasonable. For antibodies , also note that full source information must be provided (e.g. company, including sufficient address details to enable contact).

Reverse transcription quantitative PCR experiments should conform to the MIQE guidelines. Please note that normalisation against a single reference gene is only acceptable if clear evidence is presented that confirms its invariant expression under the particular conditions described. Normalisation is usually conducted with at least two validated reference genes. Ideally, authors using RT-qPCR should upload a completed MIQE checklist as part of their supplementary data, providing all ‘essential’ information on the checklist. For further guidance see Graeber et al. (2011) . Please see the Minimum reporting standards section of this guide for full guidance.

6. Tables and Boxes

Each numbered table (e.g. Table 1, Table 2) should have a concise, descriptive heading , with any further essential explanation added as a footnote. The heading should provide enough detail to understand the table without referring to the main text (i.e., it should be 'stand-alone'), although there is no need to redefine abbreviations not specific to the table or give full species names where this information has already been provided. Tables should not exceed two pages of a published paper and should ideally be in portrait orientation. Please create tables using the table tool in Microsoft Word. All tables should be cited in sequence in the main text.

Boxes are a way of expanding on information in a review paper without disrupting the flow of the main text. They could be about the general area (e.g., containing information indirectly related to the paper) or be more spe­cific (e.g., explaining a particular process in detail). Alternatively, boxes can be used to express an opinion or a particular point of view on a controversial topic within a review. Typically, boxes will include some text and an image or explanatory dia­gram and should have a descriptive one-line heading. Text in boxes is not includ­ed in the word limit. Boxes should not run over more than one page.

The inclusion of a ‘ Key Developments Box ’ is an essential element of all Expert View articles. This box should highlight four to six papers from the past two years, each summarised in a couple of sentences. Please see our Expert View guidance for more details. Boxes are optional for other review papers (e.g. Darwin Reviews and Flowering Newsletter Reviews).

7.1 Figure legends

As well as being included underneath each figure, a list of figure legends should appear at the end of the manuscript file, after the tables. Each numbered legend (e.g. Fig. 1, Fig. 2) should begin with a concise, single-sentence description of the figure. It should go on to provide enough detail to understand the figure without referring to the main text. A description of any symbols should be given in full (do not include actual character symbols in the legend) unless a key is included in the figure itself. Micrographs must include a scale bar, ideally with the length provided on the image (but otherwise indicated in the legend).

Figure legends should detail the statistical methods used and state whether tests were one- or two-sided. Common tests (t-test, simple χ2 tests, Wilcoxon, Mann–Whitney tests and one-way and two-way ANOVA tests) can be identified by name, but more complex techniques must be detailed in full within the materials and methods section. The figure legend should also clearly state the exact sample size (n) for each experimental group. A description of sample collection, including a statement on whether measurements were taken from distinct samples (biological replicates) or whether the same sample was repeatedly measured ( technical replicates ) should be provided.

Review and other papers that reproduce previously published figures or data, should clearly state this within the figure legend and appropriate permissions must be sought as required. Please consult the Permissions section of this guide for full details.

7.2 Figure accessibility and Alt text

Authors are encouraged to provide alt text (alternative text) with their figures. Good alt text ensures that individuals with visual impairments or those using screen readers can comprehend the content and context of your figures. The aim of alt text is to provide concise and informative descriptions of your figure so that all readers have access to the same level of information and understanding, and that all can engage with and benefit from the visual elements integral to scholarly content. Including alt text demonstrates a commitment to accessibility and enhances the overall impact and reach of your work.

To submit alt text with your manuscript, please include it alongside figure legends in the manuscript file.

Please see the Figure accessibility and alternative text section of our Editorial Policies page for advice and further details about preparing alt text for figures.

7.3 Figure preparation

JXB has clear requirements on the preparation of figures, including the use of composite images, figure manipulation, and data duplication. Please consult the Figure Policy prior to submitting your manuscript.

Please make figures as clear as possible. Figures should not contain more than one panel unless the parts are logically connected. The use of very large figures with numerous panels should be avoided. Add labelling where there are multiple panels using capital letters (A, B, C etc.). In general, use Helvetica Neue or a similar sans serif font for lettering. For other labelling in the figures the font- size should be uniform; between 8 and 10 pt at expected final publication size is ideal. For micrographs, a scale bar with length indicated on the image is best. Line weights should be between 0.5 and 1.5 pt. Preferred symbols, in order, are closed circles, open circles, closed squares, open squares, closed triangles, and open triangles; these should be no smaller than 1 mm (height/diameter) at expected final publication size. Avoid using mathematical symbols. Variables that are italicised within the main text of the manuscript should also be italicised in figures. Use negative exponents to indicate units in the denominator (e.g. mmol m –2 s –1 ).

Resolution at final publication size should be no less than 300 dpi and at no less than 1080 pixel width.

For revised manuscripts, figures should not be included in the (Word/rtf) manuscript file. They should instead be uploaded as a separate file or files. For photographs and composite figures, the preferred format is .tiff; for other figures, such as diagrams and graphs, .eps, .pdf, .doc or .ppt are also acceptable. For initial submission, figures can be uploaded as part of a single PDF file that includes the text, figures and tables.

Each figure should be clearly labelled (Fig. 1, Fig. 2, etc.) and should include the full figure legend. They should all be cited in sequence in the main text.

The use of colour in figures is encouraged, and there is no charge. All figures provided in colour will be published online in colour. Please save colour figures with RGB and always follow friendly practices for those with colour vision deficiencies , for example, by avoiding use of red and green colour coding . Please see the Oxford University Press (OUP) guidance on Making Figures Accessible for more information.

Authors should keep ready access to all original images, which should be high-quality, unedited, uncropped, and high resolution. These may be requested during peer review.

7.4 Preparation of graphs

JXB encourages transparent and detailed presentation of data. Therefore, graphical presentations of quantitative data should use plots that show the distribution of datasets. Simple bar charts showing the mean and error bars should include symbols representing the individual data points when n ≤ 10. Larger datasets (n > 10) should be presented as box plots, violin plots, or in other appropriate forms that illustrate data distribution. The figure legend should describe which features are represented in the box- or other plots used (e.g., mean or median, standard deviation or percentiles). Variables that are italicised within the main text of the manuscript should also be italicised in graphs. Use negative exponents to indicate units in the denominator (e.g. mmol m –2 s –1 ).

Axes scales should include a zero origin unless the parameter represented by the axis cannot have a zero value. A truncated axis is permissible if necessary to illustrate relatively small but statistically significant differences between samples, but the axis should still include a zero origin and a clearly marked axis break to alert the reader to the modified scale.

7.5 Cover Images

Authors are encouraged to submit original images to be considered for the cover of the journal. Cover art may come directly from or be closely related to a paper in the issue. Please provide images in the same final format as a figure: i.e., ideally as a .tiff and at a minimum 300 dpi at publication size. Dimensions for cover images are as follows:

  • One image, landscape option: 216mm width x 161mm height
  • Two images side-by-side, portrait options: 108mm width x 161mm height (each)

Images may be uploaded as additional supplementary files at submission (initial submission or revision stage) or emailed to the editorial office at any time during the review process or shortly after acceptance. Please provide the manuscript ID number/title and a brief description of the image and the credit.

8. Supplementary Data

Authors may include supplementary data, but because such data do not receive a DOI and are not searchable, we encourage authors to consider instead uploading supplementary data to a public repository in the interests of transparency and accessibility. You can read more about the benefits of submitting data to a public repository, such as Zenodo , in the JXB Data Policy pdf. JXB also encourage all authors to consider uploading the raw data associated with their paper (for example, raw gel images, unedited micrographs, and numerical data used to generate graphs and tables) to a public repository such as Dryad , Zenodo or Figshare . More information can be found in the data deposition section of this guide.

Supplementary data may be submitted if they add valuable information that is not essential to a full understanding of the main paper or cannot practically be included in the paper. Supplementary data may contain figures, tables, datasets, protocols, and/ or videos. Methods essential for understanding the paper should be included in the main manuscript file and not as supplementary data.

To differentiate supplementary data from the figures and tables in the manuscript, please add an S to items in this section and refer to them in your manuscript as follows: Supplementary Fig. S2, Supplementary Table S1, etc. Add labelling where there are multiple panels in figures using capital letters (Supplementary Fig. S1A, Supplementary Fig. S1B, etc.). Within each category (e.g. tables, figures, videos) all items of supplementary data should be cited in sequence in the main text.

Add a supplementary data section, immediately after the discussion in your main paper, giving each item a brief, single-sentence description . For example:

Supplementary data

The following supplementary data are available at JXB online.

  • Table S1. Cowpea germplasm lines used in this study.
  • Table S2. Primer sequences for the amplification of DNA fragments flanking 20 randomly selected SNPs.
  • Fig. S1. Principal component analysis of the cowpea germplasm used in this study, showing the distribution of the eight accessions chosen for the SNP discovery panel.
  • Fig. 2. Osmotic stress tolerance phenotypes of independent UP12_8740-OE lines, empty vector-transformed control lines, and wild-type plants under 6% or 10% PEG treatment.
  • Dataset S1. Bait library sequence used in Capture-Seq.

Ideally provide all supplementary data as a single PDF file , but complex tables and datasets are preferred as Excel files, and video files as .mov, .mpg, .avi and animated .gif files. Ensure video can be easily viewed with widely available software (e.g. Windows Media Player or QuickTime Player). For easy viewing and downloading, keep the size of the file(s) small where possible, i.e. <10 MB.

Please label each supplementary data file according to its contents, for example:

Supplementary Dataset S1; Supplementary Figure S1–S5; files with various content: Supplementary Figures S1–S2 and Tables S1–S3.

Supplementary data must be fully understandable on their own so full legends must be included in the file(s). Please do not add line numbers to supplementary data files and do not include supplementary data in the main manuscript file. These files should be uploaded in the dedicated supplementary files upload area of the submission site.

Although these data will be subject to full peer review, they are not professionally copy-edited so it is essential that authors check them meticulously.

9. Author Contribution

All research papers must include an author contribution statement, clearly identifying the contribution made by each author. JXB uses the Contributor Roles Taxonomy ( CRediT ) for describing individual author contributions to papers. All authors should agree to this statement prior to submission. The author contribution statement should appear after the acknowledgements and before the conflict of interest statement. Please see the Authorship section of this guide for further guidance. An author contribution statement is not required for review papers.

An example of an author statement following the CRediT taxonomy is shown below:

RG-C: conceptualization; YL, DM, MMJ, XZ, and RG-C: methodology; YL, DM, and WY: formal analysis; YL, DM, KB, WY, and MMJ: investigation; RG-C: resources; YL: data curation; DM, and RG-C: writing - original draft; YL, WY, MMJ, and RG-C: writing - review & editing; DM, WY, XZ, and RG-C: visualization; XZ, and RG-C: supervision; RG-C: funding acquisition

10. Conflict of Interest

Authors are required to reveal any financial interests or connections, direct or indirect, or other situations that might raise the question of bias in the work reported or the conclusions, implications or opinions stated. This may include pertinent commercial or other sources of funding for the individual author(s) or for the associated department(s) or organisation(s), personal relationships, or direct academic competition. Existence of a conflict of interest does not preclude publication in the journal.

It is the responsibility of the corresponding author to disclose on submission all pertinent commercial and other relationships of all authors. Any conflict of interest should be declared in a ‘Conflict of interest’ statement to be included in the paper after the acknowledgements and author contribution section. The statement is required for all papers.

When considering whether to declare a conflicting interest or connection, please consider the conflict of interest test: is there any arrangement that would embarrass you or any of your co-authors if it were to become public after publication and you had not previously declared it? In other words, authors should declare perceived conflicts as well as direct conflicts. A detailed definition of conflict of interests can be found on the Oxford University Press Conflict of Interest page .

If authors have no conflict of interest, this should be stated as follows in the conflict section: ‘No conflict of interest declared’.

11. Funding Statement

Authors must name their funding sources, or state if there are none, in a separate section entitled ‘Funding’. This should appear after the Conflict of interest section and is required for all papers.

Funding statements should follow the format described below, unless specified otherwise by a funder:

  • The sentence should begin: ‘This work was supported by …’
  • The full official funding agency name should be given, e.g., ‘the National Cancer Institute at the National Institutes of Health’ or simply, ‘National Institutes of Health,’ not ‘NCI’ (one of the 27 subinstitutions) or ‘NCI at NIH’ (See full RIN-approved list of UK funding agencies.)
  • Grant numbers should be complete and accurate and provided in brackets as follows: ‘[grant number ABX CDXXXXXX]’
  • Multiple grant numbers should be separated by a comma as follows: ‘[grant numbers ABX CDXXXXXX, EFX GHXXXXXX]’
  • Agencies should be separated by a semi-colon (plus ‘and’ before the last funding agency)
  • Where individuals need to be specified as the recipient of certain sources of funding, the following text should be added after the relevant agency or grant number ‘to [author initials]’.
  • An example is given here: ‘This work was supported by the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme [grant agreement XXXXXX] and the National Science Foundation (NSF) [grant XXXXXX to M.P.]

Authors without funding should use the following statement: ‘This research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors.’

Please see the Funding and Crossref Funding Data Registry section of this guide for further information.

12. Data Availability

To encourage authors to make their primary data available and facilitate the discoverability of such data, all research papers submitted to JXB must have a ‘Data availability’ statement. Primary data are data that have been gathered directly from specific sources (usually experimentation or observation). The primary data are usually used to prepare the figures and tables in a paper. For papers published in JXB, deposition of primary data in a publicly available data repository is mandatory for some types of data and strongly encouraged for others. The ‘Data availability’ statement should clearly identify the locations where all types of deposited primary data can be accessed.

Mandatory deposition of primary data is required for sequence data (nucleic acids or proteins or), omics datasets (e.g. RNA-seq, array data, proteomics mass spectra), molecular interaction data, and any other primary data where there is a field-specific, publicly available database. Deposition of these types of data is required prior to publication. More information about mandatory data deposition requirements and recommended repositories can be found in our Data Deposition Guidelines section.

While JXB does not mandate the deposition of other types of primary data, we strongly encourage authors to submit other primary data associated with their paper, such as raw phenotypic data used for statistical analysis, to a public repository (such as Dryad , Zenodo or Figshare ).

Providing large datasets in supplementary information is strongly discouraged, with authors encouraged instead to make such data available in repositories. The benefits of uploading data to repositories rather than as supplementary material can be found in the JXB Data Policy for Supplementary Data . Extra results presented in the supplementary material that do not feature in the paper must not be referenced within the data availability statement.

The ‘Data availability’ statement should report where the primary data generated within the paper are available, outline the terms of use, and provide accession codes or other unique identifiers where data have been made publicly available. It is expected that novel materials used and described in the paper are made available for non-commercial research purposes and a statement concerning availability, or restrictions on availability, should also be included in the ‘Data availability’ section. The statement should also include details of where to access previously unreported code used to generate results reported within the paper that have been made publicly available in appropriate repositories (e.g. GitHub). Authors should not use the data availability statement to refer to data that were not generated within the paper, with the exception of large-scale collated datasets subject to meta-analysis.

If data are subject to an embargo or other restrictions on availability, such as third-party restrictions, the reason for this must be provided and a release date given. As depositing primary data in a repository is encouraged we recommend authors avoid using such statements unless absolutely necessary.

The ‘Data availability' statement should be included in the manuscript after the funding statement.

The vast majority of JXB review papers do not require a ‘Data availability’ statement, as JXB review articles are prohibited from including previously unpublished experimental data. The only exception to this is reviews that include meta-analysis of previously published data – in this case, the sources of the original data and the locations of any newly compiled datasets should be provided in a ‘Data availability’ statement.

Examples of ‘Data availability’ statements can be found in the table below. Authors may need to combine statements to best describe the availability of primary data (for example, for primary RNA-Seq datasets uploaded to the Gene Expression Omnibus (GEO) and for general phenotypic data uploaded to Dryad).

If you have any concerns or questions about sharing your data, please contact the editorial office at [email protected] .

More information on Data Availability Statements can be can be found on the OUP Research Data page .

Types of data associated with your paper and where it should be deposited Data deposition requirement Example text to add to your ‘Data availability’ statement

Primary data that does have a field-specific database, for example: sequence data (proteins or nucleotides), omics datasets (e.g. RNA-Seq, array data, mass spectra), molecular interaction data, and any other data where there is a field-specific, publicly held database. This should be deposited in the appropriate repository (see our Data Deposition Guidelines for advice on repositories).

The [e.g RNA-Seq] data underlying this article are available in [repository name, e.g. the Gene Expression Omnibus (GEO) Database] at [URL], and can be accessed with [unique identifier, e.g. accession number, deposition number].

Primary data that does not have a field-specific database (for example, raw phenotypic data). This should be deposited in a general, cross-disciplinary public repository (e.g. Dryad, Zenodo, Figshare).

1. All primary data that supports all the results in the paper

2. Specific pieces of primary data that support individual results in the paper

1. All primary data to support the findings of this study are openly available in [repository name e.g “Dryad”] at [http://doi.org/[doi]] (Reference).

2. The [e.g. raw leaf measurements] data that support the findings of this study are openly available in [repository name e.g “Dryad”] at [http://doi.org/[doi] (Reference).

Large-scale collated datasets subject to meta-analysis included in Review papers.

Review papers may not include unpublished experimental data and the data availability statement for these papers should confirm this (e.g. This review contains no new experimental data).

Supporting [type of] data that were analysed, but not generated, as part of this review are from previously published studies and datasets and are cited within the text at relevant places. The processed data are publicly available at [repository name e.g “Zenodo”] at [http://doi.org/[doi].

Specific pieces of primary data supporting the study not deposited due to valid restrictions on use (for example, species location data).

The [e.g. species location] data presented in this article are not publicly available at the time of publication due to [restrictions listed e.g. their containing information that could compromise a conservation location].

Primary data where a third-party restriction exists.

The data underlying this article were provided by [third party] under licence / by permission. Data will be shared on request to the corresponding author with permission of [third party].

No primary data supporting the study have been deposited as the authors have opted not to.

The primary data supporting this study were not made publicly available at the time of publication.

13. References

Previously published work must be acknowledged by appropriate citation in the main text and a full reference list. References in research and review papers should be balanced and appropriate for setting context and demonstrating novelty. Reviews may be cited for general background information, but authors should cite original research papers when referencing key advances in the field that underpin the current work. Authors should not cite retracted papers. Citations to preprint papers are allowed but should not be used to support key statements in a manuscript. Restrictions on the number of references apply only to eXtra Botany papers: Insights and Viewpoints should have a maximum of 20 references; Editorials up to 20 references in addition to all the papers included in the issue. Please see our guides for Insights and Viewpoints and Editorials for more details.

Attention to detail when referencing ensures correct crosslinking, enabling links from the reference to the full-text document.

In-text citation style examples:

Chen and Zhu (2015) have shown ... ... towards the root tip (Zhu, 2014; Chen and Zhu, 2015).

Note the use of chronological rather than alphabetical order.

When papers are by more than two authors use et al . (e.g. Zhao et al ., 2015).

If several papers by the same author in the same year are cited, use letters to distinguish between them (e.g. 2016 a, b ).

If several papers by different authors with the same surname and in the same year are cited, use author initials to distinguish between them (Z. Zhang et al., 2017; X.Y. Zhang et al., 2017).

For papers in preprint servers add Preprint (Castel et al ., 2019, Preprint)

We encourage authors to deposit all supporting data either in public repositories or in supplementary data, and hence ‘data not shown’ and ‘unpublished results’ are not permitted.

Reference List

References should be listed in alphabetical order (without numbering). As with citations, references must be accurate and follow journal style (see examples below). Note use of full journal titles (e.g., Journal of Experimental Botany not J.Exp.Bot).

For a paper with up to ten authors, list them all; for more than ten authors, list the first three followed by et al .

Citation of papers from e-journals or from papers available ahead of print should include the DOI or URL rather than volume/page numbers.

Only published papers or preprints should be cited. Papers submitted to journals and those in preparation should not be cited in the reference list.

Divisions of botanical study

Biochemists study the effects of soil, temperature, and light on plants. Plant morphologists study the evolution and development of leaves, roots, and stems, with a special focus on the tissues at various points on stems (called buds) where the cells have the ability to divide. Plant pathologists investigate the causes of plant disease and the effect that pathogens, such as bacteria and fungi, have on forest trees, vegetable crops, grain, and ornamental plants. Economic botanists study the impact of plants as they relate to human needs for food, clothing, and shelter. Plant geneticists study the arrangement and behavior of genes (the physical units of heredity) in plants in order to develop crops that are resistant to diseases and pests. Fossil plants are studied by paleobotanists to determine the earliest appearances of various groups of plants and the conditions under which they existed.

Plants and animals depend on one another for their survival. Plants are primary producers that, through photosynthesis, provide nutrients that animals use to carry out vital body processes. Animals, in turn, contribute to plant distribution, plant pollination, and every other aspect of plant growth and development. Together with zoology (the study of animals), botany is an important aspect of the study of ecology (the interrelationship of living things and their environments).

History of botany

The field of botany began to take form with the work of Greek philosopher Aristotle (384–322 B.C.), the first person to classify plants. He divided them into categories according to size and appearance. Many years later, Swedish botanist Carolus Linnaeus (1707–1778) contributed greatly to the study of botany by devising a comprehensive classification system for plants that is still used today. In 1753, Linnaeus published his Species Plantarum, in which he classified every known species of plant according to its structure and its similarity to other species. He also gave each plant a two-part name (called binomial nomenclature), consisting of the genus (the biological classification between family and species) and a second descriptive word.

The first scientific experiment in plant nutrition was conducted by Belgian physician Jan Baptista van Helmont (1577–1644). In growing a tree using only water as nourishment, van Helmont proved that the soil in which the tree was planted was not the only source of plant nutrients. English physiologist Stephen Hales (1677–1761) studied plant transpiration (loss of water from the surfaces of plant leaves and stems) and is credited with establishing plant physiology as a science.

During the nineteenth century, advances were made in the study of plant diseases, spurred by the potato blight in Ireland in the 1840s. Caused by a fungus that destroyed the entire potato crop, the potato blight resulted in over one million deaths from starvation and led to a mass migration of Irish to America.

The modern science of plant genetics developed from the work of Gregor Mendel (1822–1884), an Austrian botanist and monk. His breeding experiments with pea plants provided information on the nature of genes and their role in the inheritance of characteristics between generations. He formulated the Mendelian laws of inheritance, which were applied after 1900 to plant breeding.

Research in botany includes developing new and hardier species of crops, controlling plant diseases, discovering new medicines from plants, and studying the effects of human intervention (such as pollution and logging) on plant life. Exploring ways of maintaining an ecological balance that continues to sustain both plant and animal life is an important subject of study as well.

An alteration in plant phenotypes assisted by their responses to the environmental stimuli (=tropism) has been fundamental to understand the " plant sensitivity " that plays a crucial role in plants' adaptive success. Plants succeed through the deployment of moderators controlling polar auxin-transport determining organ bending. Stimulus-specific effectors can be synthesized by the outer peripheral cells at the bending sites where they target highly conserved cellular processes and potentially persuade the plant sensitivity at large. Remarkably, the peripheral cells require different time-intervals to achieve the threshold expression-levels of stimulus-specific molecular responders. After stimulus perception, tropic curvatures (especially at growing root-apices) are duly coordinated via integrated chemical and electrical signalling which is the key to cellular communications. Thus, the acquired phenotypic alterations are the perplexed outcome of plant's developmental pace, complemented by the sensitivity. A novel aspect of this study is to advance our understanding of plant developmental-programming and the extent of plant-sensitivity, determining the plant growth and their future applications.

  • Early universe
  • Galaxies and clusters

The Cosmic Gems arc is among the brightest and highly magnified galaxies observed at redshift z ∼ 10.2 1 . However, it is an intrinsically UV faint galaxy, in the range of those now thought to drive the reionization of the universe 2–4 . Hitherto the smallest features resolved in a galaxy at a comparable redshift are between a few hundreds and a few tens of parsecs 5,6 . Here we report JWST observations of the Cosmic Gems. The light of the galaxy is resolved into five star clusters located in a region smaller than 70 parsec. They exhibit minimal dust attenuation and low metallicity, ages younger than 50 Myr and intrinsic masses of ∼ 10 6 M ⊙ . Their lensing-corrected sizes are approximately 1 pc, resulting in stellar surface densities near 10 5 M ⊙ /pc 2 , three orders of magnitude higher than typical young star clusters in the local universe 7 . Despite the uncertainties inherent to the lensing model, they are consistent with being gravitationally bound stellar systems, i.e., proto-globular clusters (proto-GCs). We conclude that star cluster formation and feedback likely contributed to 3 shape the properties of galaxies during the epoch of reionization.

Local Employment and Economic Development Programme (LEED)

We offer best practice on how to create more and better quality jobs through effective policy implementation and local initiatives.

research paper botany pdf

About the LEED Programme

The OECD Local Employment and Economic Development Programme (LEED) provides practical solutions for how to build vibrant communities with more and better jobs for all. It achieves this by supporting effective policy implementation and local initiatives.

LEED was created over forty years ago to support OECD governments at national, regional and local level with innovative approaches to local job creation, social inclusion and economic growth.

Our mission

LEED brings together policy makers and practitioners from around the world to identify, evaluate and disseminate promising approaches to local development. In the wake of the COVD-19 crisis, building back better lies in advancing innovative solutions to build resilient local labour markets, particularly to ensure a just twin green and digital transition.

How it works

We bridge national policies and local communities by:

  • Providing strategies to better tailor national policies to different local realities.
  • Bringing together policies across all levels of government alongside actions from civil society and the private sector to support integrated local development.

We serve as a gateway for local communities to the OECD by:

  • Translating cutting-edge research into concrete guidance on “what works” at the local level.
  • Creating opportunities for local practitioners, social innovators, entrepreneurs and civic leaders to exchange with international experts and peers.
  • Bringing the local voice to broader OECD discussions and debates.

LEED’s work is steered by a committee of representatives from ministries of employment and labour, social affairs, economy, and regional development from OECD and non-OECD countries. Many local and regional governments also engage in projects with LEED. 

The Programme is housed in the OECD’s Centre for Entrepreneurship, SMEs, Regions and Cities . 

Our approach

Local development.

Local development is the process of building stronger, more vibrant communities, where economic opportunities flourish, and all residents can enjoy a high quality of life. It’s about job creation and competitiveness, but not only. Issues such as inclusion, social connectedness and civic pride are also at the heart of a modern approach to local development. 

Local employment and skills

A skilled workforce represents an important tool for local economies to attract new talent and investment. In fast-changing labour markets, local employment and skills policies need to better connect employers with the talent they seek and prepare all people for the future of work.  Involving a wide range of stakeholders through local partnerships contributes to helping local communities thrive while seeking to not leave anyone behind. 

Culture, create sectors and sports

Cultural and creative sectors are an often-overlooked driver of development. However, they generate economic wealth, create jobs, and spur innovation, as well as making places more attractive to live, work and invest in. Similarly, both professional and grassroots sport contributes to happier, healthier and more inclusive societies and can be used as a catalyst for development, for example through the hosting of major sporting events. 

Social economy and innovation

The social economy and social innovation are powerful tools for creating more inclusive, creative and sustainable societies and economies.

The social economy and social innovation help with things like reducing poverty, improving healthcare and education, providing housing, developing communities, conserving the environment, and making sure everyone has fair access to resources. Both work to solve social and environmental problems and make sure everyone benefits from changes in society. They make sure marginalized groups aren't forgotten and that everyone gets a fair share of the benefits.

The social economy and social innovation actively address socio-economic and environmental challenges and contribute to a just twin transition by aiming for marginalised groups to not be left behind and that the benefits of these transitions are shared equitably. This includes challenges related to poverty alleviation, healthcare, education, housing, and community development, as well as environmental conservation and promoting fair access to resources.

In recognition of its importance, the OECD Recommendation on the Social and Solidarity Economy and Social Innovation was issued in 2022 to further help countries, regions and cities make the most its potential.

Inclusive entrepreneurship

Unlocking entrepreneurial talent across the population contributes to inclusive and sustainable growth, labour market attachment and social and financial inclusion. Inclusive entrepreneurship policies aim to offer all people an equal opportunity of creating a successful business, regardless of their gender, age, place of birth or other personal characteristics.
