摘要
PPR (pentatricopeptide repeat)蛋白家族是最大的蛋白质家族之一,其主要定位于陆生植物线粒体与叶绿体中。研究表明,PPR蛋白在植物生长发育过程中起着至关重要的作用。本文对PPR蛋白结构特征及分布展开简单的介绍并围绕PPR蛋白的功能进行详细阐述,PPR蛋白作为序列特异性RNA结合蛋白,参与植物细胞器mRNA转录后加工(编辑、加工、剪接等),并影响植物的生长发育、细胞质雄性不育恢复和胚胎发育。本文旨在阐明PPR蛋白在植物生长发育中的作用,为探究PPR蛋白在植物生长发育分子机制提供研究思路和科学依据。
PPR (pentatricopeptide repeat) protein family is one of the largest protein families, which is mainly located in mitochondria and chloroplasts of terrestrial plants. Studies have shown that PPR proteins play a vital role in plant growth and development. In this paper, the structural characteristics and distribution of PPR proteins are briefly introduced and the functions of PPR proteins are elaborated in detail. As a sequence-specific RNA binding protein, PPR proteins are involved in the post-transcriptional processing (editing, processing, splicing, etc.) of plant organelle mRNA, and affect plant growth and development, cytoplasmic male sterility recovery and embryonic devel-opment. The purpose of this paper is to clarify the role of PPR protein in plant growth and devel-opment, and to provide research ideas and scientific basis for exploring the molecular mechanism of PPR protein in plant growth and development.
