Abstract
A flaD (sinR) null mutation depressed sigD-lacZ expression only two- t o fourfold, whereas a flaD1 point mutation depressed it almost complet ely. Introduction of pHYSigD, a sigma(D)-overproducing plasmid, correc ted the filamentous phenotype common to both sinR mutants; autolysin s ynthesis was restored partially and completely in the flaD1 and flaD ( sinR) null strains, respectively. Flagellin synthesis and motility wer e not restored at all in either strain.
