For many plant researchers protein transport to the vacuole is primarily a
question of the mechanisms underlying the recognition of vacuolar proteins
and their segregation in the Golgi apparatus from other products of the
secretory pathway. Autophagy is an alternative process by which proteins
can enter the vacuole. Examples of apparent selective autophagy are seen in
cereal grains depositing storage proteins, and in rubber particle
sequestration. Non-selective autophagy is observed during starvation and in
senescing tissues. Another overlooked aspect of vacuolar protein transport
involves the participation of prevacuolar sorting compartments, some of
which may function as endosomes.Keywords: Autophagy,
endosome, plasmalemmasome, multivesicular body, vacuole
