Role of Salicylic Acid in Survival Strategy of Plants under Changing Environment

Abstract

In recent years salicylic acid (SA) has been the focus of intensive research due to its function as an endogenous signal mediating role in defense responses after pathogen attack. SA antagonizes gene induction by the stress signaling molecule jasmonic acid (JA). It has also been found that SA plays a role during the plant responses to abiotic stresses. The discovery of its targets and understanding of its mechanism of the action in physiological and molecular processes could help in the sustainable plant productivity. Present report focused on various survival strategies of plants under changing environment and the role of SA in cross-talk signaling, osmoregulation, anti-oxidative system and induction of protein kinases under adverse environmental conditions.
