The genetic engineering of drought resistant crops

Genetic engineering has been used for nearly two decades to grow varieties of crops that resist diseases and insects, require fewer pesticides and take less land and water to grow. Drought tolerance is a complex trait that can involve many different genes, corresponding to different ways the plant can respond to drought genetic engineering can manipulate only a few genes at a time. Drought is one of the most important environmental stresses affecting the productivity of most field crops elucidation of the complex mechanisms underlying drought resistance in crops will. Of genetic basis of drought resistance in crop plants is a pre- requisite for a geneticist to evolve superior genotype through either conventional breeding methodology or biotechnological. Genetic engineering can be done with plants, animals, or bacteria and other very small organisms genetic engineering allows scientists to move desired genes from one plant or animal into another genes can also be moved from an animal to a plant or vice versa another name for this is genetically.

Coming to a cornfield near you: genetically induced drought-resistance the us department of agriculture is preparing to approve a new strain of corn that has been engineered to thrive in drought. Genetic control of leaf traits related to drought resistance various leaf traits have been associated with dr mechanisms and these traits are highly used to evaluate dr of crops. Genetic engineering drought tolerant plants: although not a crop plant, arabidopsis has played a vital role in the understanding of the basic processes underlying stress tolerance, and the knowledge obtained has been trans­ferred to a certain degree to important food plants. Crop genetic engineering and molecular-marker methods make the improvement of drought-resistant germplasm possible transgenic crops are also being improved to manage water stress transgenic crops are also being improved to manage water stress.

Genetic engineering has allowed new options for im­ proving the nutritional value, flavor, and texture of foods transgenic crops in development include soybeans with. Genetically modified crops that are drought-tolerant or water-efficient are a global technological solution that must be researched, developed and applied to help reduce water use in the agricultural sector. Most current gm crops have been engineered for resistance to insects, tolerance to herbicides (weed control products) or both figure 1 currently grown gm crops in the us, traits for which they are modified, and percent of total acreage of the crop that is planted to gm varieties.

Through genetic engineering, crops have been modified to tolerate salty soils, be more drought resistant and increase their rate of photosynthesis to take advantage of limited sunlight. Tanzania's first-ever genetically modified crop — a field trial of drought-tolerant maize intended to benefit small-scale farmers suffering the effects of climate change — is proceeding well. Idaho state university professor dring crowell is attempting to create, through genetic engineering, drought-resistant potato and soybean plants that require less water to grow he has already genetically engineered a relatively simple plant, arabidopsis, to make it more drought resistant.

The genetic engineering of drought resistant crops

Genetic engineering, also known as genetic modification, can help us in a variety of ways gmos can help crops and plants by enhancing nutritional content of food or even helping crops fight drought and insects. The future of drought-tolerant plants and crops due to genetic engineering show vast promise for california farmers and our state genetic engineering has been used for nearly two decades to grow varieties of crops that resist diseases and insects, require fewer pesticides and take less land and water to grow. This research project illustrates how recent advances in both molecular genetics and genetic engineering can be applied to enhance drought tolerance in plants progress has been slow and difficult, however, due to the complex effects of drought on plants.

Genetic engineering has yet to play an important role in drought tolerance only this year did agricultural biotech company monsanto introduce its first drought-tolerant seed variety, droughtgard. Modern biotechnology (marker-assisted selection or genetic engineering) needs to be increasingly used to introduce the correct combination of genes into elite crop cultivars importantly, the effects of introduced genes need to be evaluated in the field to determine their effect on salinity tolerance and yield improvement. Genetic engineering is not a silver bullet, says doug gurian-sherman, a senior scientist at ucs and the author of the report gmo crops come with their own concerns while most studies have shown genetically modified crops to be safe (pdf), many consumers still aren't convinced.

Are drought-resistant crops the solution to world hunger recently, genetically modified crops have received much criticism in the media despite the absence of any concrete scientific data that proves otherwise, opponents remain wary of crops changed by genetic engineering. Peanut (arachis hypogaea l) is one of the major oilseed crops, mainly grown in tropical and sub-tropical regions of the worldit is also rich in proteins, vitamins and ions, therefore it constitutes an important portion of food nutrition for people in these regions. Genetic engineering to introduce new traits in plants, can lead to increase in their yield, improve agricultural practices, and improve the nutritional value of food plants tolerant to weed killers, allow farmers to kill weeds without worrying about the crops. Genetic engineering — its global benefits now and beyond drought tolerant maize has been available to north american farmers since 2011 the first viral resistant ge crop was the papaya.
