Developmental phenotypes without or with extracellular cAMP stimuli. Cells were harvested from shaking cultures and allowed to develop on nonnutrient DB agar before or after the treatment with exogenous cAMP pulses at 6-min intervals for 5 h. The terminal developmental phenotypes, 36 h after harvesting, of cells without the treatment (1, wild type; 2, gβ⁻; 3, SN1; 4, SN2; 5, SN3; 6, SN4; 7, SN5) and with the treatment (8, wild type; 9, gβ⁻; 10, SN1; 11, SN2; 12, SN3; 13, SN4; 14, SN5) are shown.
