摘要: MAPK signaling cascades play important roles in regulating leaf senescence. We demonstrate that inactive ZmMEK1 induces SA accumulation and SA-dependent leaf senescence in its transgenic Arabidopsis plants. ZmMEK1 activates ZmSIMK1 and Arabidopsis MPK4 in vitro. Blockage of MAPK signaling increases endogenous SA accumulation in maize leaves.
