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.
