DREB plays a major role in response to drought mediated stress. The gene targeted in this context, Dehydration Response Element Binding Factors (DREB). using Agrobacterium mediated transformation. The current work aims to impart the gene for drought tolerance in Oryza sativa L. Transgenic Rice cultivars can be generated for drought tolerance using the Agrobacterium mediated transformations. Oryza faces various natural stress, like temperature variance, high salinity etc, drought is one of the major parameter affecting the growth and yield of the plant. Several recombinations have been made to the rice genome to impart various qualities which lack in the pure breed. Rice being the staple food of middle and south India, there is an extensive research undertaken in protecting the species and improving the quality and yield.
