Fig 1.

Positive and negative regulators of Rsr1 localize at tips of GTs and mature hyphae. Shown are representative images of strains expressing YFP-tagged versions of Rsr1 (12345) (A), Bud5 (12343) (B), and Bud2 (10055) (C). The arrows indicate enrichment of YFP-tagged proteins at septa. (C) The arrowhead denotes enrichment of YFP-Bud2 at the inner curve of a nonlinear GT; the asterisks indicate subapical enrichment of YFP-Bud2. Scale bars, 5 μm. The upper images are enlargements of the boxed areas in the lower images.
