What crops are genetically modified for drought resistance?
By harnessing these genetic advancements, scientists have successfully developed varieties of drought-tolerant rice, maize, and wheat that can be cultivated in regions facing water shortages. Perhaps the most direct way to use biotechnology to improve crop agriculture is to genetically engineer plants—that is, alter their basic genetic structure—so they have new characteristics that improve the efficiency of crop production.Biotechnological strategies useful in crop improvement include the following: (i) molecular markers for the assessment of genetic diversity and marker-assisted breeding, ii) plant tissue culture for mass propagation (iii) genetic modification for novel trait integration, and (iv) omics e.Biotechnology has helped to increase crop productivity by introducing such qualities as disease resistance and increased drought tolerance to the crops. Now, research ers can select genes for disease resistance from other species and transfer them to important crops.
What are drought-resistant crops?
Drought-resistant crops are varieties of plants that are specially designed or naturally adapted to thrive with minimal water. Additional terms for drought-tolerant include water-smart, water-conservation, dry garden, dry landscape, and desert landscaping. Drought-resistant.Drought can have a devastating effect on the yield of corn crops. When water is scarce in an area, the soil dries out and corn plants struggle to take up enough moisture to grow properly. This can lead to stunted growth and reduced yields.Maize crops grown during summer-rainy season in Asian tropics are prone to face both drought and excess moisture stress due uneven distribution patterns of monsoon rains in the region.Deikman et al. GM crops including rice, cotton, maize, and canola in field testing from 2009 to mid-2011. Many of these recent discoveries have been in rice, which is both an excellent model species for basic research, and one of the world’s most important crops.Drought resistance can be defined as the capacity of a crop to successfully produce a satisfactory yield in water shortage conditions (Luo, 2010).
What is another name for drought-resistant?
Additional terms for drought-tolerant include water-smart, water-conservation, dry garden, dry landscape, and desert landscaping. Drought-resistant. Drought-resistance is when plants can survive without water for long periods of time. Plant examples are juniper, agave, or rock cress. Drought-tolerance is when plants can sustain low water levels for a few weeks to a month. Plants, such as lavender, yarrow, and Ice plant, are considered drought-tolerant.Drought-tolerant transgenic [genetically modified (GM)] HB4® wheat carrying the drought-responsive sunflower gene Hahb4 was first developed in Argentina in 2019 and has already been approved for marketing and consumption as food/feed in at least ten countries.By harnessing these genetic advancements, scientists have successfully developed varieties of drought-tolerant rice, maize, and wheat that can be cultivated in regions facing water shortages.Drought-resistant crops often have deeper root systems, which allow them to access water from lower soil layers, making them more resilient during dry spells. These varieties can significantly reduce the risk of crop failure in arid and semi-arid regions, improving food security for millions of people.
What is the technology for drought resistance?
One of the most notable applications of CRISPR-Cas9 in agriculture is the development of drought-resistant plant varieties. This technology has shown immense potential in enhancing plant resilience against abiotic stresses such as drought and salinity. Major applications of CRISPER–Cas9 in crops and other fields. At present, CRISPR–Cas-based genome editing is extensively used in nearly all agronomically important crops, including cotton, maize, rice, wheat, soybean, and potato, as well as biofuel crops, including switchgrass.One of those improvements was gene editing (also known as genome editing or CRISPR), which is the latest advance in genetic engineering. Gene editing via CRISPR is a technology that allows researchers to correct, delete, add or modify the DNA sequence of a gene. It is faster, quicker, and much more specific than GMOs.
How drought-resistant crop plants can be produced?
The answer is: Drought-resistant crop plants can be produced through selective breeding and genetic modification. Selective breeding involves crossing plants with desirable drought-resistant traits over several generations to enhance this characteristic. Wheat is very sensitive to drought during the early seedling stages and germination, unlike many other crops. Seedlings of crops plant are extremely sensitive to drought stress conditions (Mahpara et al.
