Microautophagy and macropexophagy may occur simultaneously in Hansenula polymorpha.
We subjected methanol-grown cells of wild type Hansenula polymorpha simultaneously to nitrogen depletion and excess glucose conditions. Both treatments induce the degradation of peroxisomes, either selective (via excess glucose) or non-selective (via nitrogen limitation). Our combined data strongly suggest that both processes occur simultaneously under these conditions. The implications of these findings on studies of autophagy and related transport pathways to the vacuole in yeast are discussed.
