(F) In vivo epifluorescence microscopy following neosynthesized alcAp-UapA-GFP in a single hypha at 120, 130, 140, 150, 160 and 170 min, under overexpressing (derepression/ethanol-induction) conditions, as described in Materials and methods. Notice that UapA labels the perinuclear ER rings (white arrows).
