14-3-3蛋白参与植物应答非生物胁迫的研究进展

14-3-3蛋白是一种在真核生物细胞中普遍存在且高度保守的蛋白。该蛋白在大多数物种中由一个基因家族编码,并以同源或异源二聚体的形式存在。不同的14-3-3蛋白同工型具有不同的细胞特异性,可通过识别特异的磷酸化或非磷酸化序列与靶蛋白相互作用。14-3-3蛋白在植物生长和发育的各个方面都起重要作用。本文主要围绕植物14-3-3蛋白的种类、结构、磷酸化或非磷酸化识别序列及其响应干旱、冷冻、盐碱、营养和机械胁迫等的分子机制研究进展进行综述。

Research progress on the 14-3-3 protein involved in plant responses to abiotic stress

The 14-3-3 protein is a ubiquitous and highly conserved protein in eukaryotic cells. In most species, it is encoded by one gene family and exists as a homologous or heterologous dimer. Different 14-3-3 protein isoforms have different cell specificities and interact with target proteins by identifying specific phosphorylation or non-phosphorylation sequences. The 14-3-3 protein in plants plays an important role in plant growth and development. In this paper, we reviewed the types, structures, sequences of phosphorylation or non-phosphorylation, and molecular mechanisms of plant 14-3-3 proteins under drought, cold, salinity, nutrition, and mechanical stress.
