摘 要:摘 要: RNA编辑普遍存在于陆生植物中,在高等植物叶绿体中以C→U的替换为主,可能是叶绿体产生功能蛋白的重要方式。近年来,使用体外分析、叶绿体转化和紫外交联等技术,使叶绿体RNA编辑机制的研究取得较大进展。本文对这些新的进展进行了概述,并对高等植物叶绿体RNA编辑研究中有待解决的问题进行了展望。

Abstract: Abstract: RNA editing can occur in all major land plants. The higher plant editing mostly involves C to U conversion in chloroplast genomes. It is essential for correct gene expression and protein folding. So far, RNA editing has made rapid progress by using in vitro editing system, UV cross-linking assays and chloroplast transfect technology. In this review, we summarize all new advances of RNA editing in higher plant chloroplasts. In the end, we also discuss some problems which need to be solved in the future.
