摘　　要：蛋白质的泛素化途径在植物应答生物及非生物胁迫中发挥重要作用。近年来,E3泛素连接酶BRUTUS(BTS)因参与了植物生长发育及应答多种逆境胁迫的调控过程,逐渐引起国内外学者的广泛关注。本文就BTS及其同源蛋白的结构特征进行了详细阐述,并综述了BTS应对矿质营养胁迫、重金属污染胁迫、干旱胁迫、高光强胁迫及病原菌胁迫等生物及非生物胁迫的作用机制。同时,本文分析了目前研究中存在的问题,并对BTS其他的潜在功能及未来研究方向进行了展望。The ubiquitination pathway of proteins plays an important role in plant responses to biotic and abiotic stresses.In recent years,the E3 ubiquitin ligase BRUTUS(BTS)has gradually attracted extensive attention from scientists worldwide because of its involvement in the regulation of plant growth and development and responses to a variety of stresses.In this paper,the structural characteristics of BTS and its homologous proteins in plants were described in detail,and the mechanisms of BTS in response to biotic and abiotic stresses such as mineral nutrient stress,heavy metal pollution stress,drought stress,high light intensity stress,and pathogen stress were reviewed.At the same time,this paper summarized several problems in current related studies,and it looks forward to other potential functions of BTS and future research directions.
