that these increases in cyclic amp concentrations mediated at least part of the increased sensitivity of quiescent cells to competence factors was substantiated by the observation that 0.01 to 1 mm monobutrylcyclic amp or 8-bromocyclic amp also caused a concentration-dependent potentiation of competence formation in quiescent cells during a transient exposure to platelet-derived growth factor .
