| 摘 要： | 14-3-3蛋白是高度保守并在真核生物中普遍存在的一类调节蛋白。不同的14-3-3蛋白同工型具有不同的细胞特异性, 并通过识别特异的磷酸化序列与靶蛋白相互作用, 被称为蛋白质与蛋白质相互作用的桥梁蛋白。在植物生长发育过程中, 14-3-3蛋白通过与其它蛋白的相互作用参与多种植物激素信号转导、各种代谢调控、物质运输和光信号应答等调控过程。该文主要对近年来有关14-3-3蛋白在植物生长发育中的调控作用, 特别是14-3-3蛋白参与调控植物激素信号转导等方面的研究进展进行综述。

| Abstract: | 14-3-3 proteins are a highly conserved acidic protein family present in all eukaryotic cells. Different isoforms of 14-3-3 proteins have different specificities in cells and can interact with target proteins by recognizing specific phosphorylation sites in the targets; these are known as “bridge proteins”. In plant development, 14-3-3 proteins interacting with other proteins regulate phytohormone signal transduction, metabolism regulation, nutrient transportation and response to light signaling, for example. Here, we summarize recent studies of the roles of 14-3-3 proteins in regulating plant development, especially phytohormone signal transduction. |
