Rice: Role and Responses Under Abiotic Stress

Abstract

The effects of abiotic stresses in rice cultivations are drastic and significantly hamper global production. Continued changing environments are accelerating and enhancing the deleterious effects on rice, a staple food crop in many Asian countries. Different biochemical and physiological processes of the rice plants are severely affected due to stresses and, thereby, is threatening the growth, yields, and production. Therefore, it is essential to explore the mechanisms of morphophysiological and biochemical responses of rice plants against different abiotic stresses. With this view, we highlighted and discussed the responses of rice against major abiotic stresses, namely, salinity, ozone, drought, and submergence, in this chapter. These pieces of information can be helpful to figure out the possible mechanisms to minimize the harmful effects of different abiotic stresses on rice, which will ultimately ensure food security.
