摘要
异三聚体G蛋白(Heterotrimeric GTP-binding proteins)是真核生物中一类重要的信号传导分子,由Gα、Gβ和Gγ3个亚基组成。异三聚体G蛋白不仅参与了植物的生长发育调控,而且还在多种非生物胁迫应答中起着重要的调控作用。本文着重介绍异三聚体G蛋白在植物非生物胁迫应答中的作用及可能的调控机制,并结合当前研究现状对未来研究方向提出展望,以期为今后深入研究异三聚体G蛋白在植物非生物胁迫应答中的调控机制提供参考。
Heterotrimeric GTP-binding proteins, which are comprised of Gα, Gβ, and Gγsubunits,are evolutionarily conserved signal transduction molecules in eukaryotes. In plants,heterotrimeric G not only plays an important regulatory role in growth and development,but also participates in the regulation of multiple abiotic stress responses. This review focuses on the roles and possible regulation mechanisms of heterotrimeric G in the abiotic stress responses of plants,and puts forward prospects for future research. This paper will provide reference for further studies on the detailed regulation mechanism of heterotrimeric G proteins in the abiotic stress responses of plants.
