FIG. 3.

Invasive growth of the common S. pombe laboratory strain 972. Cells were grown for 14 days on LNB medium at 27°C (A), 30°C (B) or 37°C (C) and imaged as described in the legend of Fig. 1. Invasive growth (B, bottom frame) occurred under the same conditions as for strain NCYC132, but pseudohyphae were not observed.
