Abstract:

Rice is the most widely consumed staple food in India and a large part of the world's human population, especially in Asia. In this review we discussed about the Morphological and molecular mechanisms for drought tolerance in rice. Rice requires high temperature above 200C but not more than 35 to 400C. The lots of work have been done in this area to find out the cultivars, resistance to drought.  Production of rice is decreasing day by day due to many biotic and abiotic stresses. Among them drought is one of the most common abiotic stress which affect yield and any other phenotypic factor of rice. There are three mechanisms are involved in drought resistance namely drought escape, drought avoidance and drought tolerance. Drought affect on the rice grain yield, chlorophyll content, plant height and no. of tillers per plant. During drought stress, proline and many other proteins provide defense against drought. It has also been discussed that how breeders improved these traits in rice by using a QTL mapping approach. Different approaches like AB-QTL analysis, gene pyramiding and association mapping can also be used for the improvement of rice.  Transgenic approach have also been adopted for rice to over-express transcription factors involved in the regulation of stress-inducible genes such as CBF/DREB1, DREB2, RD29B, RD22, and ICE1. Transgenic rice plants have been produced to over-express several candidate genes, such as Adc, P5CS, HVA1, TPS and TP, RWC3.
