The internal programs of plant development are informed in a profound way by environmental light conditions. This review summarizes the contribution of repressor proteins to the light-signaling machinery during seedling development, and discusses the integration of repressors with other, positively acting, light-signaling pathways and auxin and brassinosteroid hormone-signaling pathways. The main focus is placed on the mode of action of the COP/DET/FUS proteins, which were first identified in Arabidopsis but are now emerging in other plants. Their role in regulating protein turnover through ubiquitination is reviewed in light of parallel ongoing investigations of COP/DET/FUS homologues in metazoans and fungi.
植物发育的内部程序在很大程度上受到环境光照条件的影响。本综述总结了阻遏蛋白在幼苗发育过程中对光信号传导机制的贡献,并讨论了阻遏蛋白与其他正向作用的光信号通路、生长素和油菜素内酯激素信号通路的整合。主要重点放在COP/DET/FUS蛋白的作用模式上,这些蛋白最初在拟南芥中被鉴定出来,但现在在其他植物中也逐渐被发现。鉴于目前在后生动物和真菌中对COP/DET/FUS同源物的平行研究,本文综述了它们在通过泛素化调节蛋白质周转方面的作用。
