摘　　要： 翻译控制肿瘤蛋白(TCTP)广泛存在于各类真核生物中,是一类在进化上高度保守的同源蛋白家族。植物TCTP具有促进细胞增殖、分化和再生、对抗生物或非生物胁迫等功能,其表达受转录和翻译水平的调节,调控机理较复杂。本文从TCTP的发现与命名、研究领域与分布、植物TCTP基因的结构特点、表达特性及功能等方面进行了简要综述,旨在全面了解植物TCTP的生理生化功能,以期为进一步研究其调控机理,调控植物生长发育和培育抗逆新品种提供一定的理论参考。 Translationally controlled tumor protein( TCTP) is widely distributed in various eukaryotes. It’s a family of homologous proteins that are highly conserved throughout evolution process. In plants,their functions are mainly involved in promoting cell proliferation,differentiation and regeneration,and enhance tolerance to biotic or abiotic stress. The regulation mechanism of TCTP expression is complicated because it is regulated by the level of transcription and translation. In this paper,the discovery and naming,the research field and distribution,the structural characteristics,expression characteristics and biological functions of plant TCTP were reviewed. The aim of this study is to comprehensively understand the physiological and biochemical functions of plant TCTP,which will help to further study on its regulation mechanism,and provide reference for regulating the growth and development of plants and breeding new varieties of stress resistance.
