The extreme challenge for the future is to increase the plant productivity and yield with respect to climate change. In the current global status, aberrant climate change leads to the immense impact on the loss of million tons of crop productivity in agriculture. The consequence is becoming more pathetic by the current and imminent global changes in climate, world population increases, industrialisation toxicity, deterioration of cultivated land and freshwater insufciency. All these stresses emphasising the development of stress-resistant plants are those that have the ability to adapt and endure the growth and productivity in stressful and harsh environmental changes. It is signicant to understand plants stress response mechanism to augment the crop productivity under unfavourable or stressful environmental conditions.
