Fig. 3. Exocyst components localize to the A. gossypii Spitzenkörper. (A) FM4-64-stained hyphal tips. The arrowhead indicates an FM4-64-stained Spitzenkörper that is observed in some hyphae. (B) Correlation between growth speed and FM4-64-stained Spitzenkörper. Growth speeds of hyphae without accumulation of internal FM4-64 fluorescence in the hyphal tip are plotted on the left side of the graph; growth speeds of hyphae with a Spitzenkörper are plotted on the right side. (C) FM4-64 staining (red in the overlay) of an AgEXO70-GFP and an AgSEC3-YFP hypha (green in the overlay). Overlaps appear yellow. Scale bars: 5 µm.
