The cell morphology of the strains carrying the swi3-V5 allele across 24 h after thiamine induction. The figure shows the cells of the (a) swi3-V5 strain SPSC 1097 (b) swi3Δ swi3-V5 strain SPSC 1101 and (c) swi3Δ swi3-V5 rad4-116 strain SPSC 1102 at × 100 magnification stained with DAPI to show the nuclei at the 0 h time point and the 24 h timepoint. An additional time point at 12 h is shown for the SPSC 1102 strain. For SPSC 1097 and SPSC 1101, there was no significant difference between the cells across those 2 time points in terms of cell length, cell shape and nuclear shape. For SPSC 1102, the cells showed two distinct phenotypes, that developed from timepoint 0 to 12 to 24 h, for cells to increase or decrease in length. The nuclei of most of these cells showed irregular nuclear shapes that became more pronounced at the 24-h time point and some cells showed a compacted nucleus. The phenotypical effect of thiamine addition on the swi3-V5 strains across 24 h
