Figure 1:Fluorescence microscopy of stained P. cinnamomi mycelium at different locations. A) Each mycelium presents more than one individualized nucleous nuclei when stained with DAPI (1 mg/ml); B) A lack of division septa and actin cytoskeleton is observed in a cell wall stained with Calcofluor white (50 mg/ml) ; C) Actin distribution appears more concentrated at the hyphae extremities and adjacent to the plasma membrane when actin cytoskeleton was stained with Rhodamin-Phalloidin (0.1 μg/ml).
