Title: Biotechnology and Improved Drought Tolerance of Crops
Author: Deckard, E.L.
Description: Heat and lack of water affect how well plants will grow and produce. The loss of moisture through leaves is called evapotranspiration. Developing drought dehydration tolerance is comprised of traits that allow the plant to tolerate some degree of dehydration without the major reduction of metabolic activities. The postponement of such allow the plant to reduce transpiration or to increase water absorption. Osmotic adjustment has the greatest potential for developing drought tolerant varieties. traditional plant breeding has only had limited success. Various applications of biotechnology provide new opportunities for obtaining improved crop tolerance to drought. Biotechnology techniques of culturing plant cells, selecting cells capable of carrying out osmotic adjustment and regenerating whole plants from the drought tolerant cells should be an effective method for supplying new drought tolerant genes to breeding programs.
