Disruption of redA impairs development at mound stage. (A) Exponentially growing AX4 wild type cells and the mutants redA^- and redA-KO were starved on filter pads and photographed at the indicated times (h) after starvation. (B) AX4 fruiting bodies and redA^- yellow mounds after 48 hours starvation on filter pads are shown at lower (left) and at 5× higher magnification (right).
