Abiotic and biotic stresses,including drought,high-salinity,high-and low-temperature,and many diseases seriously affect plant growth and crop yield.Protein kinases mediate the perceiving and transducing of external environment signals via activating diverse phosphorylation pathways,regulate the expression of downstream resistant genes,and trigger multiple physiological and biochemical reactions to minimize and eliminate hazards.Based on previous studies,we reviewed the progress in the researches on plant protein kinases,such as receptor-like kinase(RLK),mitogen-activated protein kinase(MAPK),calcium-dependent and calmodulin-independent protein kinase(CDPK) and sucrose non-fermenting-1-related protein kinase(SnRK),which participate in abiotic and biotic stress signal pathways in recent years and explored signal transduction networks of diverse phosphorylation pathways in the responsive reactions.Moreover,some emphases in the future study were put forward.This paper provides the basis for deep understanding the molecular mechanism of plant resistance.
