BTB蛋白泛素化介导植物发育和逆境应答的研究进展

Advances on BTB protein ubiquitination mediated plant development and stress response

BTB(broad-complex,tramtrack,and bric-à-brac)结构域是在真核生物中发现的高度保守的蛋白质相互作用基序。含有BTB结构域的一类蛋白统称为BTB蛋白,它们广泛参与转录调控、蛋白质降解等过程。越来越多的研究表明,该基因在植物生长发育、生物与非生物胁迫等生理过程中具有重要的作用。本文以蛋白结构域为基础,系统总结了该基因家族蛋白在泛素化介导植物发育和逆境应答等过程中的研究进展,为植物中该类基因的研究提供了参考。

The BTB(broad-complex,tramtrack,and bric-à-brac)domain is a highly conserved protein interaction motif in eukaryotes.They are widely involved in transcriptional regulation,protein degradation and other processes.Recently,an increasing number of studies have shown that these genes play important roles in plant growth and development,biotic and abiotic stress processes.Here,we summarize the advances of these proteins ubiquitination-mediated development and abiotic stress responses in plants based on the protein structure,which may facilitate the study of this type of gene in plants.
