Fig. 3. Septin rings mark the site where sec3
cells start to lose apical tip growth under hyphal-induction conditions. (A) Cdc3p-GFP localization in wild-type (WYL38) yeast and hyphal cells. (B) Cdc3p-GFP localization in sec3
cells (WYL44) grown under yeast growth (left panel) or hyphal-induction conditions (center and right panels). An aliquot of cells at 3 hours of induction was also stained with Calcofluor White to visualize the cell wall (right panel). Bars, 5 µm.
