case study on genetic engineering in agriculture

The dominance of Genetically Modified (GM) crops in global agriculture is underscored by the production quantities of GM Maize and GM soybean. This review discusses the global statistics of GM crops mentioning the area of cultivation, production, and adoption rates of GM crops in detail. It relates the comprehensive overview of perception toward GM technology varying across regions, with the ...

To help demonstrate the power of biotechnology, consider the following analogy: Imagine you have two decks of cards, one red and one blue, and each deck contains all the genes of a potato.

1 Introduction. Agriculture faces severe challenges for delivering food and maintaining nutritional security through sustainable practices. relation to the concept of sustainability, sustainable agriculture is defined as a system of growing crops for the short and long-term period without damaging the environment, society, and the economy for the present and future generations (Tripathi et al ...

PETER KAREIVA and MICHELLE MARVIER. Department of Zoology, University of Washington. The commercial production of genetically engineered crops has prompted countries around the world to adopt risk assessment procedures for evaluating the safety of transgenic cultivars.

Genetic modification in plants was first recorded 10,000 years ago in Southwest Asia where humans first bred plants through artificial selection and selective breeding. Since then, advancements in agriculture science and technology have brought about the current GM crop revolution. GM crops are promising to mitigate current and future problems ...

Genetic engineering in rice is illustrated by case studies on the dwarfing gene and basmati rice, and on the possibility of producing a rice plant with C 4 photosynthesis. We conclude that the potential benefits of GM crops, especially to poor farmers in developing countries, justify investment in genetic engineering research, which must ...

The use of genetic engineering in agricultural research for development goes beyond addressing specific challenges like pest control; it also presents opportunities to enhance nutritional quality in staple crops. ... One notable case study that exemplifies the potential of this approach is the development of genetically modified (GM) papaya ...

Genetic engineering has provided humans the ability to transform organisms by direct manipulation of genomes within a broad range of applications including agriculture (e.g., GM crops), and the ...

The introduction of genetic-engineering technology in agriculture could affect labor dynamics, farm structure, community viability, and farmers' relation-ships with each other, but the extent of the social effects of GE crops are poorly understood because there has been little research on the topic to date.

COMPARING GENETICALLY ENGINEERED CROPS WITH THEIR COUNTERPARTS. An oft-cited risk of GE crops is that the genetic-engineering process could cause "unnatural" changes in a plant's own naturally occurring proteins or metabolic pathways and result in the unexpected production of toxins or allergens in food (Fagan et al., 2014).Because analysis of risks of the product of the introduced ...

Genetic variation is the basis of agricultural improvement. The aim of plant breeding is to create and exploit these genetic variations. Over the long history of plant breeding (Hickey et al., 2019), four major techniques have been used: cross-breeding, mutation breeding, transgenic breeding, and breeding by genome editing (Chen et al., 2019; Figure 1).

The importance of optimal nutrition for human health and development is well recognised. Adverse environmental conditions, such as drought, flooding, extreme heat and so on, affect crop yields more than pests and diseases. Thus, a major goal of plant scientists is to find ways to maintain high productivity under stress as well as developing crops with enhanced nutritional value. Genetically ...

Genetic engineering in agriculture involves the manipulation of an organism's genetic material to introduce desired traits or improve existing ones. This technology has facilitated the development of genetically modified crops (GMOs) that possess enhanced characteristics such as increased resistance to pests, diseases, and environmental ...

Genetic modification in plants was first recorded 10,000 years ago in Southwest Asia where humans first bred plants through artificial selection and selective breeding. Since then, advancements in agriculture science and technology have brought about the current GM crop revolution. GM crops are promising to mitigate current and future problems ...

In each case, the efficiency of ... the Agricultural Research Service ... These studies demonstrate how genetic engineering and genome editing can be used to produce fruits with enhanced flavor ...

The genetic engineering of animals has increased significantly in recent years, and the use of this technology brings with it ethical issues, some of which relate to animal welfare — defined by the World Organisation for Animal Health as "the state of the animal…how an animal is coping with the conditions in which it lives" ().These issues need to be considered by all stakeholders ...

Agricultural plants are one of the most frequently cited examples of genetically modified organisms (GMOs). Some benefits of genetic engineering in agriculture are increased crop yields, reduced ...

Widespread enthusiasm about potential contributions of genome-edited crops to address climate change, food security, nutrition and health, environmental sustainability and diversification of ...

2.4 Advantages and Criticisms of Genetic Modification in Agriculture. Genetic engineering, including gene editing, can have numerous benefits: ... According to a 2018 study, the use of herbicide-tolerant crops is estimated to have lowered herbicide use by 8%-20% compared with alternative growing methods. ... as may be the case with refined ...

The United States and the world face serious societal challenges in the areas of food, environment, energy, and health. Historically, advances in plant genetics have provided new knowledge and technologies needed to address these challenges. Plant genetics remains a key component of global food security, peace, and prosperity for the ...

This publication explains genetic engineering and its use in food, agriculture, and the environment. It answers key questions about genetic engineering, including its definition, applications, safety, ethical issues, and related regulations. The publication also discusses potential risks and concludes with resources for more information.

For example, one study found a way to reduce sulfur emissions from pig excretions 75% [4]. One other goal of genetic engineering in livestock that is being researched is to reduce the animals' capacity to feel pain [5]. Ethical Analysis. There are certainly some benefits of these methods of genetic engineering.

Population growth, climate change, and increasing human impact on land and aquatic systems all pose significant challenges for current agricultural practices. Genetic engineering is a tool to speed up breeding for new varieties, which can help farmers and agricultural systems adapt to rapidly changing physical growing conditions, technology, and global markets. We review the current scientific ...

Main conclusion While transgenic technology has heralded a new era in crop improvement, several concerns have precluded their widespread acceptance. Alternative technologies, such as cisgenesis and genome-editing may address many of such issues and facilitate the development of genetically engineered crop varieties with multiple favourable traits. Abstract Genetic engineering and plant ...
