Figure 3From: Ca2+ regulation in the absence of the iplA gene product in Dictyostelium discoideum In the presence of external Ca2 aggregation is accelerated in iplA - cells. Differentiation of the mutant and the wild type strain was assayed in parallel on agar plates supplemented with 20 mM CaCl2. Aggregate formation occurred earlier in iplA - cells (at t7) than in wild type (starting at t19) in the presence of Ca2+. The full width of the image corresponds to 12.5 mm.Back to article page
