线粒体是真核细胞内的重要细胞器,是一种遗传上半自主性的细胞器,编码与自身功能相关的部分基因,参与生命活动一些过程。植物的线粒体基因组较动物的更为复杂,且与植物细胞质雄性不育和物种进化密切相关。本文概述了植物线粒体基因组测序工作,并在此基础上,综述了植物线粒体基因组的大小、组成形式、基因组序列的结构特征、基因组成,分析表达特点、RNA编辑、序列重组,以及线粒体基因组进化、线粒体相关的雄性不育机理研究的研究进展。 |

Abstract: |
Mitochondria is an important organelle in eukaryotic cell,which offer energy,the necessity of cell life.Mitochondria have a semi-autonomous genetic system encoding part of its functional genes,which involved in a number of processes of life activities.In recent years,many progresses have been achieved in sequencing the mitochondrial genomes of higher plants.And it was found that plant mitochondrial genomes are more complicated than those of animals.And plant mitochondrial genomes have closely relationships with the cytoplasmic male sterility (CMS) and the evolution of species.So understanding the mitochondrial genome and getting more information are helpful to study the mechanism of CMS and evolution of species.In this paper,we summarized the research progress on the mitochondrial genome sequencing,and the relative alignment analysis on plant mitochondrial genomes of the size,composition,gene composition and expression,RNA editing,sequence recombination,and the research progress of the genome structure and genome evolution and male sterility mechanism. |
