Fig. 3. The developing dimA^– mutant phenocopies the dmtA^– mutant. (A,D,G) dimA^– and dmtA^– fingers tend to appear long and thin compared with wild type. (B,E,H) Migratory slugs of both mutants are also long and thin, and have a tendency to break apart (arrowheads). (C,F,I) After 24 hours the wild type has produced fruiting bodies, but both mutants produce fewer normal fruiting bodies, although stalks and spores litter the agar.
