Plants experience various abiotic stresses of low or elevated temperature, salt, drought, and heavy metals, as well as biotic pathogen and insect attack and sometimes simultaneously. These stresses have significant negative impact on survival, biomass production and crop yield resulting reduced productivity of crops (Amudha et al., 2011; Upchurch, 2008). In present scenario, population of the world is increasing at alarming rate and it is expected to reach 6 billion by year 2050. Farmlands are diminishing worldwide and food productivity is decreasing due to abiotic stresses. To meet the food necessities of such large population, we need a strategies to increase the production of the important crops such as cereals, pulses, etc., by developing the stress tolerant crops (Mahajan et al., 2005). …show more content…
