title: Genetic mapping of regulatory mutations of Bacillus subtilis riboflavin operon.
abstract: Seven mutations leading to riboflavin overproduction in Bacillus subtilis were found to be linked to the marker dnaF133 (145 degrees on the B. subtilis genetic map) by transformation. Cotransfer indexes (42.5%-61.7%) suggest that the ribC mutations are alleles of the same locus. Results of transduction and transformation crosses suggest the following order of markers:pyrD26-ts-6-dnaF133-ribC-recA1.
