From: Gdt2 regulates the transition of Dictyosteliumcells from growth to differentiation
Accelerated aggregation of gdt 2-. (A) Aggregation on non-nutrient agar. (B) Aggregation in submerged culture. Cells were harvested at exponential growth phase, washed, plated at a density of 2 × 105 cells/cm2 and incubated at 22°C. Photographs were taken after 7.5 hours (A) or 8 hours (B). Under both conditions gdt2- mutant cells start to aggregate about 1–1.5 hours earlier than wild type cells.
