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.
