FIGURE 1: The F-actin stained with rhodamine-tagged phalloidin in exponentially growing S. cerevisiae (rho+) cells (strain CRY339; Z-stack). Cells were fixed with 3.7 % formaldehyde in the presence of glucose (HCHO-fixed) (Glu+), or after 30 minutes incubation in medium without glucose (Glu-). Bar, 5 µm.
