Electron microscopy. Electron microscopy of pex11 pex25 RHO1^ts cells that produce P_AOX PEX25-mCherry. Cells were grown on glycerol/methanol/ammoniumsulphate for 5 h at permissive (35°C) and restrictive temperatures (44°C). Cross sections of the tubular-like structures are shown in B (overview of cell) and D (high magnification of B to show the tubular structure). (C) A longitudinal section through these tubular structures. Bar, 500 nm.
