Fig. 3. Developmental phenotype of cadA^– cells. Wild-type and cadA^– cells were developed on agar plates and aggregates were examined under a dissection microscope. KAX3 cells: (A) even splitting of aggregates; (B) finger structures derived from a single aggregate; (C) fruiting bodies. cadA-12 cells: (D) aggregates showing nodule-like structures protruding randomly from the surface (arrows), (E) elongated finger structures still carrying the nodule-like protrusions, often at the apical ends (arrow), and (F) fruiting bodies.
