Abstract: As plants cannot escape from adversity, they need to evolve highly sensitive and flexible physiological mechanisms to cope with various abiotic stresses in the natural environment. It has been shown that when plants are subjected to abiotic stresses in local tissues or organs, the plant is able to generate systemic responses through intercellular signaling that allows the plant to develop an acclimation to the stress (i.e., systemic acquired acclimation). Currently, a large amount of work has investigated the role of intercellular signaling molecules in systemic acquired acclimation of plants (mainly including reactive oxygen species signals, calcium signals, electrical signals, plant hormones, phosphatidylinositol, and pH signals) receptor-like protein kinases and other protein kinases in systemic signaling. Here, we mainly review the research progress of intercellular signaling in the abiotic stress-induced systemic responses in plants, and analyze the possible relationships among different signals, so as to provide reference for related research.

Key words: abiotic stress, systemic acquired acclimation, reactive oxygen species signals, calcium signals, electrical signals, plant hormones
