摘　　要：在真核生物中,由泛素介导的蛋白降解途径与植物生长发育密切相关。F-box蛋白家族是一类含有Fbox基序(motif),在泛素介导的蛋白质水解过程中具有底物识别特性的蛋白质家族。目前,从各种植物中已鉴定出大量的F-box蛋白质,这类蛋白质在植物激素的信号转导、光信号转导、自交不亲和以及花器官发育等许多生理过程中都具有重要功能。研究发现F-box蛋白在调控植物生长发育过程中所发挥的功能与其结构及泛素蛋白酶体途径密切相关。In eukaryotes, the ubiquitin-mediated protein degradation pathway was closely associated with plant growth and development. F-box protein is an expanding family of eukarvotic protein characterized by an F-box motif which has specificity of substrate recognition in the ubiquitin-mediated proteolysis. Currently, many F-box proteins have been identified in plants which play important roles in various biological processes such as hormone signal transduction, light signal transduction, self-incompatibility and floral development. Research indicated that the function of F-box protein in regulating the growth and development of the plant was closely related to its structure and the ubiquitin-proteasome pathway.
