植物泛素基因研究进展

笔者通过已有研究总结了泛素蛋白酶体系统的组成成分,单泛素、多聚泛素、类泛素基因结构及泛素系统在植物生长发育中的作用,并对E3连接酶在应对生物及非生物胁迫应激反应方面的功能取得的进展进行综述。针对现有的相关研究,提出了靶蛋白研究较少、E3连接酶的HECT家族报道不多及E3调控网络、泛素化的时间位点仍不清楚等问题。对加强克隆相关基因及基因之间互作的研究、加强靶蛋白信息研究及E3分子机制等未来泛素研究做出展望,以期为植物泛素系统、泛素基因结构及功能方面的研究提供参考。

Advances in Research on Plant Ubiquitin Genes

In this paper, the composition of the ubiquitin proteasome system, the structure of monoubiquitin, polyubiquitin, and ubiquitin-like gene and the role of ubiquitin system in plant growth and development, and the function of E3 ligase in response to biotic and abiotic stress were reviewed. In view of the existing related research, it is proposed that there are few studies on the target protein itself, few reports on the HECT family of E3 ligase, and the timing site of E3 regulatory network and ubiquitination is still unclear. The future research on ubiquitin, such as strengthening the research on cloning related genes and gene interaction, strengthening the research on target protein information and E3 molecular mechanism, is expected to provide references for the research on plant ubiquitin system, the structure and function of ubiquitin genes.
