Plants modulate the metabolism of phytohormones and their signaling pathways under drought to regulate physiological and adaptive responses. Jasmonic acid (JA) is one of the major classes of phytohormones and has been found to potentially enhance plant tolerance to various abiotic stresses, including drought. The JASMONATE ZIM-DOMAIN (JAZ) proteins are the negative regulators in the JA-signaling pathway. The JAZ protein family is explicit to plants and involved in the regulation of numerous biological processes, including drought-responsive mechanisms. In this review, we synthesize the mechanistic insight into the roles of JAZ proteins in regulation of drought responses by connecting the JA-signaling with abscisic acid-signaling to modulate drought-responsive physiological processes.
