Post-translational modification is an important mechanism to determine protein levels and/or activities in cells. The process of conjugation of ubiquitin units to particular proteins, ubiquitination, usually leads to proteasomal degradation. During the past several years considerable work has been done to reveal the role of ubiquitination in the regulation of plant signaling and development. This article focuses on recent advances made on the study of ubiquitin-mediated proteolysis of several light-related signaling pathways, such as photomorphogenesis, circadian clock function, and photoperiodic flowering.
翻译后修饰是决定细胞中蛋白质水平和/或活性的重要机制。泛素单位与特定蛋白质的缀合过程，即泛素化，通常会导致蛋白酶体降解。在过去几年中，已经开展了大量工作来揭示泛素化在植物信号传导和发育调控中的作用。本文重点关注泛素介导的几种光相关信号通路蛋白水解研究的最新进展，如光形态建成、生物钟功能和光周期开花。
