To elucidate the mechanism of StlA-induced aggregation in P. violaceum, we analyzed the phenotype of P. violaceum stlA- (Pv-stlA-) mutants in more detail. Unlike our previous results, the mutant cells did not exhibit proper chemotaxis toward glorin. Defective aggregation was not restored by glorin pulses, 8Br-cAMP, or deletion of the homologue of PufA that is a translational repressor of protein kinase A, whereas mutant cells grown in the presence of 4-methyl-5-pentylbenzene-1,3-diol (MPBD), the putative Pv-StlA product, aggregated normally without it after starvation.
