Stimulus-activated signaling pathways orchestrate cellular responses to control plant growth and development and mitigate the effects of adverse environmental conditions. During this process, signaling components are modulated by central regulators of various signal transduction pathways. Protein phosphorylation by kinases is one of the most important events transmitting signals downstream, via the posttranslational modification of signaling components. The plant serine and threonine kinase SNF1-related protein kinase (SnRK) family, which is classified into three subgroups, is highly conserved in plants. SnRKs participate in a wide range of signaling pathways and control cellular processes including plant growth and development and responses to abiotic and biotic stress. Recent notable discoveries have increased our understanding of how SnRKs control these various processes in rice (). In this review, we summarize current knowledge of the roles of OsSnRK signaling pathways in plant growth, development, and stress responses and discuss recent insights. This review lays the foundation for further studies on SnRK signal transduction and for developing strategies to enhance stress tolerance in plants.
刺激激活的信号通路协调细胞反应，以控制植物生长发育并减轻不利环境条件的影响。在此过程中，信号成分受到各种信号转导途径的中枢调节因子的调控。激酶介导的蛋白质磷酸化是通过信号成分的翻译后修饰向下游传递信号的最重要事件之一。植物丝氨酸和苏氨酸激酶SNF1相关蛋白激酶（SnRK）家族分为三个亚组，在植物中高度保守。SnRKs参与广泛的信号通路，控制包括植物生长发育以及对非生物和生物胁迫的反应等细胞过程。最近的显著发现增进了我们对SnRKs如何控制水稻中这些各种过程的理解。在本综述中，我们总结了目前关于OsSnRK信号通路在植物生长、发育和胁迫反应中作用的知识，并讨论了最近的见解。本综述为进一步研究SnRK信号转导以及制定提高植物胁迫耐受性的策略奠定了基础。
