Abstract

Soil salinity is one of the most limiting stresses for crop productivity and quality world-wide. In this sense, jasmonates (JAs) have emerged as phytohormones that play essential roles in mediating plant response to abiotic stresses, including salt stress. Here, we reviewed the mechanisms underlying the activation and response of the JA‐biosynthesis and JA‐signaling pathways under saline conditions in Arabidopsis and several crops. In this sense, molecular components of JA‐signaling such as MYC2 transcription factor and JASMONATE ZIM‐DOMAIN (JAZ) re-pressors are key players for the JA‐associated response. Moreover, we review the antagonist and synergistic effects between JA and other hormones such as abscisic acid (ABA). From an applied point of view, several reports have shown that exogenous JA applications increase the antioxidant response in plants to alleviate salt stress. Finally, we discuss the latest advances in genomic tech-niques for the improvement of crop tolerance to salt stress with a focus on jasmonates.
