Table 1. Cell cycle timing in daughter cells.

Strain	T0 (min)	T1 (min)	T2 (min)	S/G2/M (min)
Wild type	6 ± 2 (50)	19 ± 10 (50)	17 ± 9 (50)	53 ± 8 (50)
CLB3∆db	6 ± 2 (50)	0 ± 1 (50)	18 ± 10 (50)	71 ± 16 (50)

Times are mean ± SD. Number of cells scored in parentheses. We define T₀ as the time from Whi5 entry to cytokinesis (Myo1 ring disappearance) (Figure 2); T₁, time from Myo1 ring disappearance to Whi5 exit; T₂, time from Whi5 exit to bud emergence (Di Talia et al. 2007); S/G2/M, time from Myo1 ring appearance at incipient bud neck to disappearance at cytokinesis. The frame resolution was 3 min.
