PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

Improving crop yields is needed to keep up with increasing food consumption. The effect of drought stress during the crop growth periods, due to climate instability, becomes a major obstacle to increasing yields. As the world population is growing at an alarming rate, agricultural land is being decreased because of industrialization and/or forest use. Improved drought resistance and enhanced yield are important for further techniques. It is highly desirable to alter the genetic susceptibility to intensified drought and genetic engineering includes the production of specific types of genes associated with stress. Genes that confer drought tolerance and enhance the growth of plants and survival of transgenic wheat have been identified. Nevertheless, there has been less work in relation to maize, rice and other stapled crops for producing transgenic wheat. In addition, increased drought tolerance with no yield penalty is an important task in hereditary engineering. In this literature review, researchers have concentrated on the success in the production of transgenic wheat cultivars to enhance drought tolerances. In comeback to implanted genes below regulation or field circumstances, they investigated the physiological mechanisms and their resistance testing.
