Research progress on RNA editing of plant organelles

RNA editing is a crucial post-transcriptional modification widely occurred in plants and animals， playing essential biological functions. It is especially common in plant mitochondria and chloroplasts， and is of great significance for regulating 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 mechanism of RNA editing and its applications in crop improvement.
