PPR蛋白在植物线粒体和叶绿体中功能的研究进展
Research progress on functions of PPR proteins in plant mitochondria and chloroplasts
摘要
Abstract
Mitochondria and chloroplasts are semi-autonomous organelles in plants. Their functions are regulated by both their own and the nuclear information. Pentatricopeptide repeat(PPR) proteins are a large nuclear genome encoded protein family with a tri-angular five peptide repeat structure. PPRs are usually sub-located in plant mitochondria and chloroplasts,and participate in organ-elle genome transcribed RNA editing and modifications. The functions of PPRs are varied in different plant tissue and organ develop-ment processes,and also in the responses to changes of internal and external environment events. Therefore,the research on PPRs is one of the hotspots in the study of organelle functions and cytoplasm-nuclear interactions in plants. PPRs are mainly divided into two major categories,class P and class PLS,based on the types of PPR motif and their arrangement.In this study,we summarize the research progress on the functions of PPRs in plants,mainly focus on the protein structure characteristics,the sub-cellular localiza-tion of PPRs,and the functions of PPRs in mitochondria and chloroplasts to decipher the roles of PPRs in mitochondria and chloro-plasts RNA editing and processing, and their regulations with plant development. Some prospects about the problems existing in present studies are also proposed.关键词
