Drought Stress Tolerance Mechanisms in Barley and Its Relevance to Cereals uri icon

abstract

  • In the changing environment, water is the major limiting factor for crop productivity throughout the world, and there is every need to generate climate-resilient crops. Since drought is a complex phenomenon, we need to dissect various mechanisms at the physiological, biochemical, and molecular levels in order to generate crop plants with better drought tolerance but without any yield penalties. Accumulated literature points out that improvement at both source and sink levels are needed to elevate final yields under water deficit conditions. Here, we summarize the current status of plant adaptation mechanisms and the strategies that we need to carve for generating drought stress-tolerant crops like barley
