摘要:

RNA修饰是一类重要的表观遗传修饰,它是指在RNA分子的碱基或核糖上添加化学修饰基团。RNA甲基化和乙酰化是其中两种关键的修饰类型,它们通过调控生物的遗传信息来行使重要的生物功能。这两种修饰均是由writers(编码器)、erasers(消码器)和readers(解码器)三类调控因子进行动态可逆的调控,对RNA剪接、转运、翻译、运输和降解等代谢过程产生至关重要影响。近年来,随着RNA修饰检测技术的发展,研究者在植物中发现了一些新的RNA修饰位点,并证实了RNA的甲基化和乙酰化修饰在植物的生长发育以及应对生物和非生物胁迫方面起着关键的作用。本文首先概述了RNA修饰的类型及其生物学特性,并在此基础上重点回顾了近年来关于RNA甲基化和乙酰化调控因子的研究进展,最后总结了RNA甲基化和乙酰化在植物生长发育和应对胁迫过程中的功能,并展望了RNA修饰在植物中的一些新的研究方向,以期为进一步开展植物中的RNA甲基化和乙酰化修饰相关研究提供理论依据和新思路。

Abstract:

RNA modification is an important type of epigenetic modification, which refers to the addition of chemical modifying groups to the bases or ribose of RNA molecules, and can occur in a variety of RNAs, such as messenger RNAs(mRNAs), transfer RNAs(tRNAs), ribosomal RNAs(rRNAs), and cyclic RNAs(circRNAs), etc. RNA methylation and acetylation are two of the key types of modifications that perform important biological functions by regulating the genetic information of organisms. Both modifications are dynamically and reversibly regulated by three types of regulators, namely writers, erasers and readers, which have a crucial impact on different RNA metabolic processes such as RNA splicing, translocation, translation, transport and degradation. In recent years, with the development of RNA modification detection technologies, numerous studies have identified new RNA modification sites in plants and confirmed that methylation and acetylation modifications of RNAs play key roles in plant growth and development as well as in response to biotic and abiotic stresses. This paper firstly outlines the types of RNA modifications and their biological properties, and on this basis focuses on reviewing the research progress on RNA methylation and acetylation regulators in recent years, and finally summarizes the functions of RNA methylation and acetylation in plant growth and development and in response to stresses, and looks forward to some new research directions for RNA modifications in plants, with a view to providing theoretical basis and new ideas for further research related to RNA methylation and acetylation modification in plants.
