ABSTRACT
Spore formation of 15 rifampin-resistant (Rifr) mutants of Bacillus subtilis strain 168 was examined. As a pleiotropic effect of a Rifr mutation, glutamate synthase activity was lost in these mutants. Twelve of the 15 mutants examined formed as many spores as the parent, but the remaining 3 formed significantly fewer (1%) spores. One of the latter mutants characterized further (RF301) was blocked in its sporulation process at stage 0. Thus, it was concluded that a certain modification of ribonucleic acid polymerase may affect specifically the gene expression of glutamate synthase and also the sporulation process at the initial stage.
