Illustration of cytokinetic key events in different cell cycle phases in budding yeast cells. The septin ring assembles at the cell periphery during G1-phase. A dynamic myosin ring (red dotted ring) forms during G1-S-phase in a septin dependent manner. The septin hour-glass like ring splits into two rings during mitotic exit and sandwiches a stable actomyosin-ring (red ring). c, centrosome; ch, chromosomes; m, microtubules; n, nucleus.
