Abstract
Abiotic stress is the major cause of crop loss worldwide, reducing average yield of plants by more than 50%. Plants are subjected to many abiotic stresses like drought, heat, low temperature and salinity stress. Plants have adopted to live in environments where they are often exposed to different stress factors in combination. They have developed specific mechanisms that allow them to sense particular environmental changes and act in response to complex stress conditions, reducing damage while conserving important resources for growth and development. Plant triggers a specific and unique stress response when subjected to different environmental stresses. The response to change in environment can be quick, depending on type of stress and can involve either adaptation mechanisms, or avoidance mechanism.
