How have humans modified crops?

Humans have used traditional ways to modify crops and animals to suit their needs and tastes for more than 10,000 years. Cross-breeding, selective breeding, and mutation breeding are examples of traditional ways to make these changes. These breeding methods often involve mixing all of the genes from two different sources. They are used to create common crops like modern corn varieties and seedless watermelon.

What are GMOs used for?

They are also used to make ingredients that are then used in food products like cereal, snack chips, and vegetable oils. Even though you won’t find many GMO fruits or vegetables in the produce section of your grocery store, GMOs are a common part of today’s food supply.

How are public attitudes toward agricultural biotechnology influenced by the social environment?

They are largely influenced by the social environment and the mass media, particularly when the issue at stake is characterized by weak involvement and lack of direct experience. This situation applies in particular to Europe, where the de facto ban on the cultivation of GMOs in most European countries, the lack of concrete experience with labeled GM food in supermarkets and the absence of public initiatives to render a practical experience with GMOs mandatory in high school education have led to rather heteronomous views on the technology. The lack of experience with GMOs has increased the influence of stakeholders in politics in the framing of the debate. By opposing GMOs they try to assure the public of their good motives and thus gaining public trust as guardians of food safety, the environment, and social values. The situation in North America in general and the United States in particular is different since farmers, consumers, and high school students mostly have made a concrete experience with the technology and this makes it more difficult for advocacy groups to portray themselves as the voices that represent the interests of consumers and producers. In the developing world there are countries in Latin America and Asia that have embraced the technology without much public debate. However, the continent that has so far been as reluctant as Europe to embrace the technology is Africa. Apart from South Africa and a few other countries that approved of the commercial release of Bt cotton, the continent remains largely GMO free. This is however not due to genuine domestic opposition to the technology but the pressure from Europe as the largest donor to African governments and the largest importer of agricultural products from Africa.

How can we sustain the plant biotechnology revolution?

Sustaining this plant biotechnology revolution requires long-term commitment to both public and private sector research and development (R&D). In the agricultural sector, R&D is unique among industries in at least two aspects: the truly global reach of a majority of agricultural R&D; and the historical success of what has been largely a public enterprise. In relation to other industries, research and innovation in agriculture are far more geographically dispersed ( Boettiger et al., 2004 ). Private enterprises contribute roughly one-third of global agricultural R&D expenditures, whereas public research institutions make up the other two-thirds, which is evenly split between developed and developing countries ( Pardey and Beintema, 2001 ).

How can biotechnology be used to grow crops?

Another useful application of agricultural biotechnology is to give plants the ability to grow in a wider range of environments. Some plants do well only in certain climates or soil conditions. By introducing genes from other organisms, scientists can alter these plants so that they’ll grow in climates that normally would be too harsh for them. Land previously unsuited for crops can be reclaimed for food production.

How does declining diversity affect agriculture?

Decreasing diversity could lead to dangerous consequences. Entire populations of crops could die out if hit by disease. Diversity can also help keep soil healthy and prevent toxins from building up over time. Ultimately, we must weigh the potential benefits of agricultural biotechnology against the risks.

Why is the FDA so tight on genetically modified crops?

Food and Drug Administration (FDA) has tight regulations on genetically modified crops designed to ensure scientists use safe protocols when developing new crops. If we trust in science while remaining vigilant, we may find that agricultural biotechnology could help feed the world.

How can genetic manipulation help crops?

Through genetic manipulation, scientists can create crops that produce more than their unmodified counterparts. It’s also possible to introduce genes so that a crop has more nutritional value. The Golden Rice Project is a good example — scientists have used genetic engineering to produce rice rich in vitamin A. While rice already has genes that would produce vitamin A in wild species, these genes are turned off during the growth process. The genes inserted into golden rice keep the vitamin A production genes turned on.

Do scientists work on agricultural biotechnology?

Scientists working on agricultural biotechnology point out that we’ve been genetically modifying organisms for generations — we’re just much more precise now. But there are other, more specific criticisms that aren’t as easy for scientists to dismiss.

Biotech advances allow for specific changes to be made quickly, on a molecular level through over-expression or deletion of genes, or the introduction of foreign genes.

What is the role of agriculture in biofuels?

The agricultural industry plays a large role in the biofuels industry, providing the feedstocks for fermentation and refining of bio-oil, bio-diesel, and bio-ethanol. Genetic engineering and enzyme optimization techniques are being used to develop better quality feedstocks for more efficient conversion and higher BTU outputs of the resulting fuel products. High-yielding, energy-dense crops can minimize relative costs associated with harvesting and transportation (per unit of energy derived), resulting in higher value fuel products.

Why is rice considered a genetically modified food?

Scientists are creating genetically altered foods that contain nutrients known to help fight disease or malnourishment, to improve human health , particularly in underdeveloped countries. An example of this is Golden Rice, which contains beta-carotene, the precursor for Vitamin A production in our bodies. People who eat the rice produce more Vitamin A, an essential nutrient lacking in the diets of the poor in Asian countries. Three genes, two from daffodils and one from a bacterium, capable of catalyzing four biochemical reactions, were cloned into rice to make it “golden.” The name comes from the color of the transgenic grain due to overexpression of beta-carotene, which gives carrots their orange color.

How do plants adapt to drought?

The discovery of genes in plants responsible for sodium uptake has lead to the development of knock-out plants able to grow in high salt environments. Up- or down-regulation of transcription is generally the method used to alter drought tolerance in plants. Corn and rapeseed plants, able to thrive under drought conditions, are in their fourth year of field trials in California and Colorado, and it is anticipated that they’ll reach the market in 4-5 years.

How does biotechnology help in agriculture?

It offers a range of tools to improve our understanding and management of genetic resources for food and agriculture. These tools are already making a contribution to breeding and conservation programmes and to facilitating the diagnosis, treatment and prevention of plant and animal diseases. The application of biotechnology provides the researcher with new knowledge and tools that make the job more efficient and effective. In this way, biotechnology-based research programmes can be seen as a more precise extension of conventional approaches (Dreher et al., 2000). At the same time, genetic engineering can be seen as a dramatic departure from conventional breeding because it gives scientists the power to move genetic material between organisms that could not be bred through classical means.

What are biotechnology used for?

In addition to MAS, described above, a number of biotechnologies are used in breeding and reproducing crops and trees. Often these technologies are used in combination with each other and with conventional breeding approaches.

How do biotechnology aids in animal nutrition?

Biotechnologies have already resulted in animal nutrition aids such as enzymes, probiotics, single-cell proteins and antibiotic feed additives that are already widely used in intensive production systems worldwide to improve the availability of nutrients from feeds and the productivity of livestock and aquaculture. Gene-based technologies are being increasingly employed to improve animal nutrition, either through modifying the feeds to make them more digestible or through modifying the digestive and metabolic systems of animals to enable them to make better use of the available feeds. Although progress in the latter approach is likely to be slow because of gaps in our current understanding of the underlying genetics, physiology and biochemistry, one example of commercial success in high-input, intensively managed systems is the use of recombinant somatotropin, a hormone that results in increased milk production in dairy cows and accelerated growth and leaner carcasses in meat animals.

How is genetic engineering used in animals?

Genetic engineering in animals can be used to introduce foreign genes into the animal genome or, alternatively, to “knock-out” selected genes. The method most used at present involves direct microinjection of DNA into the pronuclei of fertilized eggs, but progress is being made with new approaches such as nuclear transfer and the use of lentiviruses as DNA vectors.

How does AI affect livestock?

Advances in artificial insemination (AI) and multiple ovulation followed by embryo transfer (MOET) have already had a major impact on livestock improvement programmes in developed countries and many developing countries because they speed up the process of genetic improvement, reduce the risk of disease transmission and expand the number of animals that can be bred from a superior parent – the male in the case of AI and the female in the case of MOET. They also increase the incentives for private research in animal breeding and significantly expand the market for improved parent stock.

What are the most important breakthroughs in agricultural biotechnology?

The most significant breakthroughs in agricultural biotechnology are coming from research into the structure of genomes and the genetic mechanisms behind economically important traits (Box 4). The rapidly progressing discipline of genomics is providing information on the identity, location, impact and function of genes affecting such traits – knowledge that will increasingly drive the application of biotechnology in all agricultural sectors. Genomics sets the foundation for post-genomics activities, including new disciplines such as proteomics and metabolomics to generate knowledge on gene and protein structure, as well as their functions and interactions. These disciplines seek to understand systematically the molecular biology of organisms for their practical use.

Why are plant and animal diseases so difficult to diagnose?

Plant and animal diseases are difficult to diagnose because the signs may be misleading or even entirely absent until serious damage has occurred. Advanced biotechnology-based diagnostic tests make it possible to identify disease-causing agents and to monitor the impact of disease control programmes to a degree of precision not previously possible. Molecular epidemiology characterizes pathogens (viruses, bacteria, parasites and fungi) by nucleotide sequencing, which enables their origin to be traced. This is particularly important for epidemic diseases, in which the possibility of pinpointing the source of infection can significantly contribute to improved disease control. For example, the molecular analysis of rinderpest viruses has been vital for determining the lineages circulating in the world and instrumental in aiding the Global Rinderpest Eradication Programme (GREP) (Box 11). Enzyme-linked immunosorbent assay (ELISA) tests have become the standard methodology for the diagnosis and surveillance of many animal and fish diseases worldwide, and the polymerase chain reaction (PCR) technique is especially useful in diagnosing plant diseases and is proving increasingly so also for livestock and fish diseases. The effectiveness of plant and animal health programmes is also being considerably enhanced by the development of genetic probes that allow specific pathogens to be distinguished and detected in tissue, whole animals and even in water and soil samples.

What is agricultural biotechnology?

Agricultural biotechnology is a range of tools, including traditional breeding techniques, that alter living organisms, or parts of organisms, to make or modify products; improve plants or animals; or develop microorganisms for specific agricultural uses. Modern biotechnology today includes the tools of genetic engineering.

Why do we use biotechnology in agriculture?

Researchers may use biotechnology to conduct research more efficiently and to discover things that may not be possible by more conventional means.

How are genetically engineered plants used?

Genetically engineered plants are also being developed for a purpose known as phytoremediation in which the plants detoxify pollutants in the soil or absorb and accumulate polluting substances out of the soil so that the plants may be harvested and disposed of safely. In either case the result is improved soil quality at a polluted site. Biotechnology may also be used to conserve natural resources, enable animals to more effectively use nutrients present in feed, decrease nutrient runoff into rivers and bays, and help meet the increasing world food and land demands. Researchers are at work to produce hardier crops that will flourish in even the harshest environments and that will require less fuel, labor, fertilizer, and water, helping to decrease the pressures on land and wildlife habitats.

How does biotechnology help farmers?

Biotechnology provides farmers with tools that can make production cheaper and more manageable. For example, some biotechnology crops can be engineered to tolerate specific herbicides, which make weed control simpler and more efficient. Other crops have been engineered to be resistant to specific plant diseases and insect pests, which can make pest control more reliable and effective, and/or can decrease the use of synthetic pesticides. These crop production options can help countries keep pace with demands for food while reducing production costs. A number of biotechnology-derived crops that have been deregulated by the USDA and reviewed for food safety by the Food and Drug Administration (FDA) and/or the Environmental Protection Agency (EPA) have been adopted by growers.

How has biotechnology helped the Hawaiian papaya industry?

Agricultural biotechnology has been used to protect crops from devastating diseases. The papaya ringspot virus threatened to derail the Hawaiian papaya industry until papayas resistant to the disease were developed through genetic engineering. This saved the U.S. papaya industry. Research on potatoes, squash, tomatoes, and other crops continues in a similar manner to provide resistance to viral diseases that otherwise are very difficult to control.

What is the role of the USDA in genetic engineering?

In addition to these efforts, the United States Department of Agriculture (USDA), the Environmental Protection Agency (EPA), and the Food and Drug Administration (FDA) work to ensure that crops produced through genetic engineering for commercial use are properly tested and studied to make sure they pose no significant risk to consumers or the environment.

Why are biotech crops important?
