title: Endocytosis in signalling and development.
abstract: After a long period of neglect, endocytosis in plants is finally coming of age. The constitutive recycling of plasma membrane proteins has been well established in the past few years, and recent studies report the ligand-induced endocytosis of receptors and other plasma membrane proteins. Signalling by ligand-bound receptors from endosomes has not, however, been demonstrated in plants. Although novel markers have been used to map endocytic pathways, the functional compartmentalisation of endosomes is still controversial. It is thus not clear where and how cargo proteins such as receptors are sorted towards either recycling to the plasma membrane or targeting to the vacuole for degradation.
