Rsr1p and Bud2p regulate septin Cdc3p localization during YF and HF growth. C. albicans strains MG5398 (WT), DH9237 (rsr1Δ/Δ), and MG7849 (bud2Δ/Δ), all expressing Cdc3-GFP, were grown under HF or YF conditions, and DIC and GFP filter fluorescence microscopies were used to analyze Cdc3-GFP localization. Arrowheads indicate Cdc3-GFP at the necks of the filaments. Scale bars, 10 and 5 μm (HF and YF, respectively). Adobe Photoshop v. 7 was used to process the acquired images.
