Fig. 7. Comparison of the division rate of cells silenced in different actin subfamilies. Only silencing of act4 and act9 affects the division rate, all other subfamilies show no significant difference when compared with the control (empty pPD vector). While silencing of act9 caused delayed growth, cells silenced in act4 stop dividing and start dying at 72 hours. Error bars represent s.e.m. *s.e.m.=0.
