Endocytosis and vesicle recycling via secretory endosomes are essential for many processes in multicellular organisms. Recently, higher plants have provided useful experimental model systems to study these processes. Endocytosis and secretory endosomes in plants play crucial roles in polar tip growth, a process in which secretory and endocytic pathways are integrated closely. Plant endocytosis and endosomes are important for auxin-mediated cell-cell communication, gravitropic responses, stomatal movements, cytokinesis and cell wall morphogenesis. There is also evidence that F-actin is essential for endocytosis and that plant-specific myosin VIII is an endocytic motor in plants. Last, recent results indicate that the trans Golgi network in plants should be considered an integral part of the endocytic network.
通过分泌性内体进行的内吞作用和囊泡循环对于多细胞生物中的许多过程至关重要。最近，高等植物为研究这些过程提供了有用的实验模型系统。植物中的内吞作用和分泌性内体在极性顶端生长中起着关键作用，在这个过程中分泌途径和内吞途径紧密整合。植物内吞作用和内体对于生长素介导的细胞间通讯、向重力性反应、气孔运动、胞质分裂和细胞壁形态发生很重要。也有证据表明F-肌动蛋白对于内吞作用至关重要，并且植物特有的肌球蛋白VIII是植物中的一种内吞运动蛋白。最后，最近的结果表明植物中的反式高尔基体网络应被视为内吞网络的一个组成部分。
