Expression of multicellular behaviour (rdar morphotype) is a characteristic of wild-type Salmonella typhimurium strains. The key target for the regulation of rdar morphotype expression is the agfD promoter. The regulation of two rdar morphotypes, regulated and semi-constitutive (the latter differs from the former by the insertion of A after position -17), by various environmental conditions was studied using transcriptional fusions to the regulated and semi-constitutive agfD promoters by… CONTINUE READING
