Abstract
The sul gene of B/rw (Witkin) and 26 independently isolated sul mutants were examined for their suppression of radiation sensitivity. The suppressed lon gene was demonstrated by transducing it into a K12 proC recipient. The sul gene of B/rw and all but one of the B/r mutants was found to be linked to a gene controlling azide resistance. Transduction data established the order of markers as leu azi mutT sul. One B/r mutant was found not transducible with azide resistance, sul mutations were found to suppress the capsular polysaccharide production of lon strains.Keywords
