Abstract
Induction of Myxococcus xanthus fruiting by a number of different purine-containing compounds, including cyclic adenosine 3',5'-monophosphate, is defective in a mutant resistant to 2,6-diaminopurine. Furthermore, the purine-induced fruiting of wild-type cultures is uniquely blocked by a low concentration of added glycine. These results imply that different purine-containing compounds induce fruiting through a single mechanism involving nutritional imbalance.
