The endosomal sorting complex required for transport (ESCRT) machinery is an ancient system that deforms membrane and severs membrane necks from the inside. Extensive evidence has accumulated to demonstrate the conserved functions of plant ESCRTs in multivesicular body (MVB) biogenesis and MVB-mediated membrane protein sorting. In addition, recent exciting findings have uncovered unique plant ESCRT components and point to emerging roles for plant ESCRTs in non-endosomal sorting events such as autophagy, cytokinesis, and viral replication. Plant-specific processes, such as abscisic acid (ABA) signaling and chloroplast turnover, provide further evidence for divergences in the functions of plant ESCRTs during evolution. We summarize the multiple roles and current working models for plant ESCRT machinery and speculate on future ESCRT studies in the plant field.

运输（ESCRT）机械所需的内体分选复合物是一个古老的系统，可使膜变形并从内部切断膜颈。积累了大量证据来证明植物ESCRT在多囊体（MVB）生物发生和MVB介导的膜蛋白分选中的保守功能。此外，最近令人兴奋的发现揭示了植物ESCRT的独特成分，并指出了植物ESCRT在非内体分选事件（例如自噬，胞质分裂和病毒复制）中的新兴作用。植物特定过程，例如脱落酸（ABA）信号传导和叶绿体更新，为进化过程中植物ESCRT功能的差异提供了进一步的证据。
