Abstract: SnRKs (sucrose nonfermenting-1-related protein kinases) are key protein kinases in stress responses. In response to biotic stresses, they are involved in reactive oxygen species and salicylic acid-mediated signaling transduction pathways to enhance the plant tolerance to biological stress. In response to abiotic stresses, SnRKs enhance the plant tolerance to drought, salinity and high temperatures by intracellular signaling mediated by abscisic acid (ABA), regulate cellular energy homeostasis and maintain ion balance by ABA-independent signaling. SnRKs are the main regulators in stress signaling in recent research and we give a brief outlook for future study.
