What is Agricultural Biotechnology?
Agricultural biotechnology can be defined as a sector of agriculture and biotechnology, which uses advanced biological techniques like genetic engineering for enhanced crop production. It involves the use of techniques like gene manipulation and tissue culture to bring desired changes in plant variety.
History of Agricultural Biotechnology
Human beings learned agriculture around 10,000 B.C. With time we started to domesticate various kinds of plants. Selective breeding led to the development of a new modified variety of plants. We learned to improve our productivity with the help of agrochemicals like fertilizers and pesticides around the 1930s.
How are Genetically Modified Plants Produced?
Genetic modification of crops involves inserting DNA into the genome of an organism. Production of a GM plant involves adding a specific stretch of DNA into the plant’s genome, giving it new or different characteristics, and the cells are then grown in tissue culture where they develop into plants.
Benefits of Biotechnology in Agriculture
Increased crop productivity: Since GM crops are resistant to pests and diseases, the loss is minimized. As a result, yield increases by nearly 3 folds. Some plants are developed to use water and minerals efficiently in a dry climate as well. As a result, GM crops show better productivity.
Risks and Drawbacks Associated with the Use of Biotechnology in Agriculture
Potential health risks: Consumption of GM crops can change the metabolism, growth rate, and response to external environmental factors.
Application of Genetic Engineering and Biotechnology in Agriculture
Biofertilizers and biopesticides: Biofertilizers and biopesticides are eco-friendly alternatives to agrochemicals, and they do not harm the environment. Biofertilizers enrich soil nutrients naturally by adding algae and bacteria like rhizobium.
Summary
Transgenic crops and biotechnology have been proven to be a boon. The techniques can be used to improve the quality, quantity and even help in the production of the resistant plant. Several successful plant varieties have been developed, like Bt cotton, which is pest resistant; golden rice is an example of a vitamin-rich plant.
What is in vitro selection?
In vitro selection refers to the selection of germplasm by applying specific selection pressure to tissue culture under laboratory conditions. Many recent publications have reported useful correlations between in vitro responses and the expression of desirable field traits for crop plants, most commonly disease resistance. Positive results are available also for tolerance to herbicides, metals, salt and low temperatures. For the selection criteria of major general importance in forest trees (in particular vigour, stem form and wood quality), poor correlations with field responses still limit the usefulness of in vitro selection. However, this method may be of interest in forestry programmes for screening disease resistance and tolerance to salt, frost and drought.
How do molecular markers help in genetic conservation?
The use of molecular markers to measure the extent of variation at the genetic level, within and among populations , is of value in guiding genetic conservation activities and in the development of breeding populations in crops, livestock, forestry and fisheries. Studies carried out using these technologies in fish and forest tree species have revealed high levels of genetic variation both among and within populations. Livestock species are characterized by a high degree of genetic variation within populations, whereas crops exhibit a higher degree of variation across species. Data from other approaches, for example field observation, often cannot provide such information or are extremely difficult to collect.
How does micropropagation work?
Micropropagation involves taking small sections of plant tissue, or entire structures such as buds, and culturing them under artificial conditions to regenerate complete plants. Micropropagation is particularly useful for maintaining valuable plants, breeding otherwise difficult-to-breed species (e.g. many trees), speeding up plant breeding and providing abundant plant material for research. For crop and horticultural species, micropropagation is now the basis of a large commercial industry involving hundreds of laboratories around the world. In addition to its rapid propagation advantages, micropropagation can also be used to generate disease-free planting material (Box 7), especially if combined with the use of disease-detection diagnostic kits. There have been some attempts to use micropropagation more widely in forestry. Compared with vegetative propagation through cuttings, the higher multiplication rates available through micropropagation offer a more rapid dissemination of planting stock, although limited availability of desirable clones is an impediment to its wider adoption in forestry.
How are genetic linkage maps used?
Genetic linkage maps can be used to locate and select for genes affecting traits of economic importance in plants or animals. The potential benefits of marker-assisted selection (MAS) are greatest for traits that are controlled by many genes, such as fruit yield, wood quality, disease resistance, milk and meat production, or body fat, and that are difficult, time-consuming or expensive to measure. Markers can also be used to increase the speed or efficiency of introducing new genes from one population to another, for example when wishing to introduce genes from wild relatives into modern plant varieties. When the desired trait is found within the same species (such as two varieties of millet – Box 6), it may be transferred with traditional breeding methods, with molecular markers being used to track the desired gene.
How are molecular markers used?
Molecular markers have been widely used for identifying genotypes and for “genetic fingerprinting” of organisms . Genetic fingerprinting has been used in advanced tree-breeding programmes in which the correct identification of clones for large-scale propagation programmes is essential. Molecular markers have been used to identify endangered marine species that are either inadvertently captured in wild fisheries or that are purposefully taken illegally. Genotype verification is used intensively in parentage testing of domestic animals and for tracing livestock products in the food chain back to the farm and animal of origin.
What is agricultural biotechnology?
Agricultural Biotechnology is the use of new scientific techniques based on our understanding of DNA to improve crops and livestock that are not possible with conventional breeding alone. This can be achieved in part by modern molecular plant breeding techniques such as marker-assisted selection (MAS).
How does biotechnology affect agriculture?

What are some examples of biotechnology?
For example, one of the most important products generated through agricultural biotechnology has been the introduction of transgenic crop plants which confer herbicide tolerance, in such a way that herbicides can be sprayed on transgenic crops without causing damage while detouring the growth of neighboring weeds.
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.
Why do insects die?
The insects soon die as a result of pores which are created in the gut cell membrane. The first generation of biotechnology crops focused on agronomic input traits that helped farmers; however, their value was not clear to the general consumer who is disconnected to the demands of farming.
