Reversible Protein Phosphorylation Regulates Transmembrane Ion Movements in Plant Cells

蛋白激酶和蛋白磷酸酶催化的可逆磷酸化是植物细胞中多种信号转导途径中重要的组成因子.本文对蛋白质可逆磷酸化通过调节多种离子跨膜运动而参与植物细胞激发子信号途径、毒性物质诱导的钙离子内流、盐胁迫适应、气孔运动以及蛋白质可逆磷酸化参与胞外与胞内之间Ca2+状况信息传递,调节花粉管顶端Ca2+离子通道活性进行综述,以揭示蛋白质可逆磷酸化在植物细胞离子跨膜运动中的调控作用,为蛋白质可逆磷酸化调节植物生长发育、响应逆境胁迫等机理的研究提供参考.

Reversible protein phosphorylation catalyzed by protein kinases and phosphatases is a key factor in many signal transduction pathways in plant cells. In this review, we summarize that reversible protein phosphorylation play a very important role in elicitors-invoked signal pathway,toxins-induced Ca^2＋ influx, adaptation of cell to salt stress, communication between external and internal Ca^2＋ status in plant cells, stomatal movement, and involved in the regulation of plasma membrane-located Ca^2＋ channel activity in pollen tube tip. This review is aimed at revealing the signal transduction of reversible protein phosphorylation in the regulation of plant growth and development and adaptive responses to stress environments by mediating transmembrane ion movement.
