The Key Roles of Mediator Complex in Plant Responses to Abiotic Stress
中介体复合物作为真核生物转录机器中的重要共激活子,起着连接RNA聚合酶Ⅱ和不同转录因子从而调节基因转录的作用.当植物遭遇各种非生物胁迫时,中介体复合物通过整合胁迫信号并激活或抑制靶基因的表达,进而帮助植物适应环境胁迫.本文总结了植物中介体复合物的发现,及其在干旱、盐、极端温度下的功能及调节机制,并探讨了中介体复合体的未来研究方向,有助于理解中介体复合物在非生物胁迫应答中的重要功能.
Mediator complex,as an essential coactivator in the eukaryotic transcription machinery,plays a crucial role in bridging RNA polymerase Ⅱ and various transcription factors to regulate gene transcription.When plants encounter various abiotic stresses,the mediator complex integrates stress signals and activates or suppresses the expressions of target genes,thereby helping plants to adapt to environmental stress.This article summarizes the discovery of the mediator complex,and different functions of plant mediator complex under drought,salt,and extreme temperature conditions.It also discusses future research directions of the mediator complex to gain a deeper understanding of its role in regulating responses to abiotic stress.
