| 摘要: |
| RNA编辑是一种重要的转录后修饰机制，广泛发生于动植物中，发挥重要的生物学功能。尤其在植物线粒体和叶绿体中更为常见，对调控细胞器基因表达、维持其功能完整性以及植物发育与逆境适应具有重要意义。近年来，随着高通量测序技术与生物信息学工具的不断进步以及功能基因组研究深入，植物RNA编辑的研究取得了显著进展。本文系统总结了植物RNA编辑的研究方法，重点梳理了植物线粒体与叶绿体中RNA编辑的最新研究成果，涵盖关键编辑因子（如PPR、MORF与DYW蛋白）的识别机制与作用模式，进一步探讨了RNA编辑在植物应对非生物胁迫中的潜在功能。通过汇总近年来的研究进展，本文旨在为深入解析RNA编辑的分子机制及其在作物改良中的应用潜力提供理论依据与研究参考。 |

| Abstract: |
| RNA editing is a crucial post-transcriptional modification widely occurred in plant and animal, playing essential biological functions. It is especially common in plant mitochondria and chloroplasts, involved in organelle gene expression, functional maintenance, and plant development and stress adaptation. In recent years, significant progress has been made in plant RNA editing research due to advances in high-throughput sequencing, bioinformatics tools and functional genomics. In this review, we first summarize the current research methodologies for RNA editing, then focus on the recent findings related to mitochondrial and chloroplast RNA editing, emphasizing the roles and mechanisms of key editing factors such as PPR, MORF, and DYW proteins. Moreover, we explore the potential functions of RNA editing in plant responses to abiotic stresses. This review aims to provide theoretical insight and references for further elucidating the molecular mechanisms of RNA editing and its applications in crop improvement. |
