Abstract
Sporulation of Bacillus subtilis can be induced, in the presence of excess ammonia, glucose and phosphate, by many purine derivatives under conditions of partial growth inhibition. Some of the compounds are known inhibitors of purine nucleotide synthesis. For most compounds the effect is counteracted by adenine and guanine. Partial growth inhibition by amethopterin (methotrexate) causes sporulation in the absence of purines but not in their presence. Unable to induce sporulation at any concentration are inhibitors of DNA, RNA, and protein synthesis as well as base or amino acid analogs that are incorporated into these polymers.
