Plants are challenged by abiotic stress factors such as low water availability (drought), excess water (flooding/waterlogging), extremes of temperatures (cold, chilling, frost, and heat), salinity, mineral deficiency, and toxicity. The negative effects of abiotic stresses bring about changes in plant metabolism, growth, and development, in extreme cases leading to plant death. This is a specific concern in agriculture where stress-related changes limit productivity and can lead to intolerable economic loss to the breeders. It has been projected that abiotic stresses may reduce crop production ...
