摘　　要：五肽重复序列(Pentatricopeptide repeat,PPR)家族是高等植物最大的基因家族之一,在大多数已测序的植物物种中有超过400个成员。水稻基因组中有491个PPR基因。越来越多的证据表明PPR蛋白参与叶绿体或线粒体基因的转录后调控,包括RNA成熟、编辑、内含子剪接、转录本的稳定性和翻译起始。RNA代谢对叶绿体和线粒体的生物发生和功能有重要作用,因此,对光合作用、呼吸作用和植物的发育及其对环境的响应具有深远的影响。本文综述了水稻PPR蛋白通过对线粒体或叶绿体RNA编辑、剪接等作用调节水稻的多种发育途径,总结了水稻PPR蛋白参与生物和非生物胁迫响应的最新研究进展。The PPR family is one of the largest gene families in higher plants,with over 400 members in most sequenced plant species.The rice genome consists of 491 PPR genes.The increasing evidence shows that PPR proteins are involved in post-transcriptional regulation of chloroplast and/or mitochondrial genes,including RNA maturation,editing,intron splicing,transcript stabilization,and translation initiation.The synergy of RNA metabolism has profound implications for both chloroplast and mitochondrial biogenesis and function,and therefore,for photosynthesis,respiration,and the development of plants and their response to the environment.In this review,we summarized the recent advances in rice PPR proteins,including the regulation of various developmental pathways through mitochondrial or chloroplast RNA editing and splicing,and involvement in responses to biological and abiotic stresses in rice.
