Abstract

Messenger RNAs (mRNAs) are the templates for protein translation but can also act as non-cell-autonomous signaling molecules. Plants input endogenous and exogenous cues to mobile mRNAs and output them to local or systemic target cells and organs to support specific plant responses. Mobile mRNAs form ribonucleoprotein (RNP) complexes with proteins during transport. Components of these RNP complexes could interact with plasmodesmata (PDs), a major mediator of mRNA transport, to ensure mRNA mobility and transport selectivity. Based on advances in the last two to three years, this review summarizes mRNA transport mechanisms in local and systemic signaling from the perspective of RNP complex formation and PD transport. We also discuss the physiological roles of endogenous mRNA transport and the recently revealed roles of non-cell-autonomous mRNAs in inter-organism communication.

追踪信使:基于 mRNA 的植物通讯新进展
信使核糖核酸(mRNA)是蛋白质翻译的模板,但也可以作为非细胞自主信号分子发挥作用。植物将内源和外源线索输入移动 mRNA,并将其输出到局部或系统靶细胞和器官,以支持特定的植物反应。移动 mRNA 在运输过程中与蛋白质形成核糖核蛋白(RNP)复合物。这些 RNP 复合物的成分可与 mRNA 运输的主要媒介质膜(PD)相互作用,以确保 mRNA 的流动性和运输选择性。基于过去两三年的研究进展,本综述从 RNP 复合物形成和质膜转运的角度总结了局部和系统信号转导中的 mRNA 转运机制。我们还讨论了内源性 mRNA 运输的生理作用,以及最近揭示的非细胞自主 mRNA 在机体间通讯中的作用。
