Actin at the zone of cell–cell contact visualized by scanning confocal microscopy in fus1Δ and fus1Δ for3Δ. (Related to Fig. 2.) Images of homothallic h90 fus1Δ GFP-CHD (left) and h90 fus1Δfor3Δ GFP-CHD (right) cells obtained by laser-scanning confocal microscopy (LSM 710; Carl Zeiss). Time interval is 2 s. The video is sped up sevenfold. Long dynamic, unfocalized actin cables are observed in fus1Δ. No actin cables were observed in fus1Δ for3Δ. Contrast was adjusted to optimize cable visualization. Bar, 1 µm.
