植物光合基因psb A的结构及表达调控综述

A review of the structure and expression of plant photogene psb A

着重从以下几个方面比较系统地论述了目前对植物光合基因 psb A 的研究进展:1.独具的功能;2.在叶绿体基因组中的定位及拷贝数;3.密码子使用特性;4.表达调控特点,包括转录、转录后、翻译、翻译后4个水平的调控特点以及光等因素对调控的介导;5.编码产物 D_1蛋白的光抑制现象,并对尚待深入研究的主要问题作了阐述. 光合基因:psb A;

The expression of plant photogene is a complex multistep processes.In this review,recent progresses toward pbotogene psb A were gathered and the emphases were placed on its fometion,location and copy number in chloroplast genome,characters of the codes,expressional regulation at transcriptional,posttranscriptional, translational and posttranslational levels and photoinhibition of D_1 peptide.Moreover,the main fields required to provide more information were discussed,including expressional light-regulation and identification of its DNA (RNA)binding proteins.
