Constitutive endocytosis in characean internodal cells is independent of an intact actin cytoskeleton.
We have investigated constitutive endocytosis in internodal cells of the characean green algae. The endocytic tracer FM1-43 accumulated in distinct plasma membrane domains that are probably enriched in sterol-like substances. Internalization of the dye was active but independent of an intact actin or microtubule cytoskeleton.
