Endocytosis is crucial for cell polarity and apical membrane recycling in the filamentous fungus Aspergillus oryzae.

ABSTRACT: Establishing the occurrence of endocytosis in filamentous fungi was elusive in the past mainly due to the lack of reliable indicators of endocytosis. Recently, however, it was shown that the fluorescent dye N-(3-triethylammoniumpropyl)-4-(p-diethyl-aminophenyl-hexatrienyl)pyridinium dibromide (FM4-64) and the plasma membrane protein AoUapC (Aspergillus oryzae UapC) fused to enhanced green fluorescent protein (EGFP) were internalized from the plasma membrane by endocytosis. Although the occurrence of endocytosis was clearly demonstrated, its physiological importance in filamentous fungi still remains largely unaddressed. We generated a strain in which A. oryzae end4 (Aoend4), the A. oryzae homolog of Saccharomyces cerevisiae END4/SLA2, was expressed from the Aoend4 locus under the control o
