Figure 3.
Colony and single cell morphology of the wild-type SN152 (WT) and the mutant strains. (A, B) Colony morphology after 2 d of growth on solid SC-Met−/Cys− or SC-Met+/Cys+ medium at 30° were shown. (C, D) Cells from an overnight liquid SC-Met−/Cys− or SC-Met+/Cys+ culture at 30° were examined under microscope. Bar = 100 μm.
