摘要:

PPR( pentatricopeptide repeats)基因家族是在植物中发现的最大家族之一,它是以35个氨基酸为重复单位连续排列在一起为主要特征的,它可能通过与细胞器转录本的结合,在线粒体或叶绿体中起着至关重要的作用。文章对PPR基因的结构特征、在不同染色体及生物体内的分布及其生物学功能的研究现状进行综述。

Abstract: One of the largest gene families discovered in plants is characterized by tandem arrays of pentatricopeptide repeats(PPRs), which play essential roles in mitochondria or chloroplasts, probably via binding to organellar transcripts. In this review, we summarized the current knowledge in the study of PPR family, which include the structure of PPR gene, the distribution in the chromosome arms and other genomes, as well as the biological function of PPR gene.
