Abstract

ABSTRACT AtDREB1A transgenic groundnut shows tolerance to drought and salinity stresses Tanmoy Sarkar, Radhakrishnan T, A.

E-mail:radhakrishnan.nrcg@gmail.com Introduction: Groundnut (Arachis hypogaea L.) is an important leguminous cash crop for farmers particularly in the semi-arid tropics and its productivity is adversely affected by various abiotic stresses. Abiotic stress tolerance is a polygenic character making use of regulated expression of large number of genes in response to a particular stress. So, genetic transformation using transcription factor controlling signal transduction pathway and expression of various stress inducible genes offers a viable option to address the problems in groundnut cultivation. DREB1A/CBF3 transcription factor recognizes dehydration responsive elements (DRE/CRT) of promoter region of stress-inducible downstream genes under abiotic stress; subsequently regulates their expression in Arabidopsis thaliana and conferred stress tolerance (Pellegrineschi et al. 2004, Bhatnagar-Mathur et al. 2007).This research work is aimed to develop transgenic groundnut tolerant to abiotic stress by incorporating the transgene AtDREB1A under the control of stress-inducible rd29A promoter in groundnut cv. GG20.
