FIG. 3.
Developmental phenotypes of red mutants. A) Developmental phenotypes of redB::Ω4439, ΔredB, Δ(redCDEF), Δ(redCD), and Δ(redEF) were analyzed in wild-type (DZ2) (DZ4657, DZ4663, DZ4659, DZ4665, or DZ4667, respectively) (A) or ΔespA (DZ4227) (DZ4658, DZ4664, DZ4660, DZ4666, or DZ4668, respectively) (B) backgrounds. Ten microliters of 2 × 109/ml cells was spotted on clone fruiting agar (18) and incubated at 32°C. Pictures were recorded at 24 and 48 h of development. Strains bearing ΔredA or an insertion in redG in the wild-type (DZ4661 or DZ4669, respectively) or ΔespA (DZ4662 or DZ4670, respectively) background behaved essentially as the respective ΔredB mutants with respect to fruiting body formation.
