Caption: In the unicellular green alga Chlamydomonas reinhardtii bursts of rapid division cycles produce clusters of daughter cells, a process that is controlled by the retinoblastoma (RB) tumor suppressor pathway. The clusters with small cells are from a strain that is missing RB, and the clusters with large cells are missing a protein that is repressed by RB.
