Nettetfurrow ingression were observed. They also found that even in-terphase cells are competent to initiate a cleavage furrow. Together, these pieces of evidence show that local acti-vation of RhoA is sufficient to initiate furrow ingression ir-respective of the position of cell cortex and cell cycle phase (Fig. 1).

Because hof1∆ and cyk3∆ single mutants have relatively mild defects but hof1∆ cyk3∆ double mutants are nearly dead, it has been hypothesized that these proteins contribute to parallel pathways. However, …
