Abstract
Plants are severely affected by salinity due to its high magnitude of adverse impacts and worldwide distribution. Phytohormones are thought to be the most important endogenous substances involved in the mechanisms of tolerance or susceptibility of plants to salinity stress. The role of phytohormones under salinity stress is critical in modulating physiological responses that will eventually lead to adaptation to an unfavorable environment. Ethylene and gibberellins (GAs) are involved in mitigating the adverse effects of salinity stress by initiating a set of defense response or increasing plants’ growth. However, both these phytohormones influence each other’s action. On the one hand, GA is known to increase ethylene synthesis, and on the other hand, its signaling is itself affected by ethylene, and therefore, this interaction opens a cross talk between them. The present study focuses on both individual and interactive effect of the two in salinity tolerance to find out whether they have independent action or their action is dependent on each other.
