种子热激蛋白研究进展

Advances in heat shock proteins of seed

植物种子在成熟、贮藏与萌发中会合成大量蛋白质,其中包括具有重要作用的热激蛋白。研究种子热激蛋白的结构与功能,能够揭示热激蛋白与种子正常发育、抵抗高温等逆境胁迫的相关性,阐释热激蛋白在种子中的作用机理。通过培育具有抵抗高温逆境的种子可以提高植物种子活力、保护种质资源,实现种子生产的高产与稳产以达到推动农业经济发展的目的。本文从热激蛋白的合成、分类、特点与功能等方面进行了概述,并详细分析了热激蛋白在植物种子成熟、贮藏和萌发中的作用,并对热激蛋白在蛋白质组学上的研究进行了总结。提出利用蛋白质组学分析牧草种子劣变过程中热激蛋白合成类型与数量的应用前景。

A large number of proteins containing heat shock proteins（ HSPs） can be synthesized in the process of maturation,storage and germination in plant seed. The correlation between HSPs and maturation or thermo tolerance of seed is revealed by studying the structure and function of HSPs so as to interpret the role of HSPs in seed. Seed vigour could be improved and the germplasm resources could be protected by cultivating plant seed with heat-resistance. The purpose of promoting agricultural economic development will be achieved by means of realizing the high and stable yield in seed production. This paper summarizes the synthesis,classification,characteristics and function of HSPs. Furthermore,the roles of HSPs during the plant maturity,storage or germination are described in detail,and some researches of proteomics on HSPs are summarized. The applied progress utilized the proteomics to analysis the synthesis type and numbers of HSPs is provided during forage seed deterioration.
