Title of Presentation: Title: Genetic Engineering for climate intelligent crops

Abstract

Plants being sessile needs to face the wrath of changing environment and hence a serious threat to crop productivity worldwide. In turn plants also elicits responses to tolerate/ avoid these changing environment. These stress responses vary, depending on stress, duration and intensity; and many a times plants succumbs. Genetic engineering of crop plants for re-programming of stress responses is of utmost necessity for agricultural sustainability. Here I shall present two stories: development of transgenic Brassica juncea (Indian mustard) for drought and salinity
tolerance; AtALMT1 overexpression in blackgram enhances its tolerance for aluminum toxicity in acid soil. In the first story overexpression of an Arabidopsis Late Embryogenesis Abundant protein (AtLEA4-1) rendered Indian mustard tolerant to drought and salinity in controlled environmental conditions. Whereas, in the second malate transporter (AtALMT1) overexpression led to exudation of malate in a citrate exuding plant species blackgram leading to enhanced aluminum tolerance in acid soil.
