| Research Abstract |
We have examined relationship between the formation and enlargement of plant vacuole and autophagic processes. We have shown that the macroautophagy pathway contributes to the enlargement of pre-existing vacuoles in Arabidopsis root cells. On the other hand, the precursor structure of the central vacuole seems to be formed through an autophagic process that is different from conventional macroautophagy. We have revealed that such a novel autophagic process play a role in the generation of vacuoles in miniprotoplasts, in which the central vacuole has been removed.
