Traffic to the endocytic compartment of plants Academic Article uri icon

abstract

  • The endocytic pathway of plants has been identified and partially characterized using nonspecific membrane-bound and fluid phase probes . The function of endocytosis in plants is, however, unknown. We shall describe how ultrastructural histochemistry, immunocytochemical analyses and fluorescence imaging have been used to explore the physiology and function of the endocytic pathway in plant protoplasts and whole cells.Cationized ferritin (CF) can be used as a marker of plasma membrane uptake in plant protoplasts. Several different organelles become labeled upon exposure of protoplasts to CF: clathrin-coated vesicles (CV), the partially coated reticulum (PCR), the Golgi complex (GC), the multivesicular body (MVB), and the vacuole (V). These organelles also participate in the pathways of secretion and delivery of protein to the lysosome (vacuole). What are the sites of overlap/divergence among the secretory, endocytic and lysosomal pathways in these cells?
