Abstract: 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 ZINC FINGER INFLORESCENCE MERISTEM
(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 the regulation of drought responses by connecting the JA-signaling
with abscisic acid-signaling.
