Plant vacuoles are essential organelles for plant growth and development, and have multiple functions. Vacuoles are highly dynamic and pleiomorphic, and their size varies depending on the cell type and growth conditions. Vacuoles compartmentalize different cellular components such as proteins, sugars, ions and other secondary metabolites and play critical roles in plants response to different biotic/abiotic signaling pathways. In this review, we will summarize the patterns of changes in vacuole morphology in certain cell types, our understanding of the mechanisms of plant vacuole biogenesis, and the role of SNAREs and Rab GTPases in vacuolar trafficking.
植物液泡是植物生长发育所必需的细胞器，具有多种功能。液泡具有高度的动态性和多形性，其大小因细胞类型和生长条件而异。液泡将蛋白质、糖类、离子和其他次生代谢物等不同的细胞成分分隔开来，并在植物对不同生物/非生物信号通路的响应中发挥关键作用。在这篇综述中，我们将总结某些细胞类型中液泡形态的变化模式、我们对植物液泡生物发生机制的理解，以及SNARE蛋白和Rab GTP酶在液泡运输中的作用。
