title: [Operon of riboflavin biosynthesis in Bacillus subtilis. VIII. Localization of group ribC markers in relation to the structural gene cluster group].
abstract: Regulatory markers of ribC group were located on the chromosome of Bacillus subtilis by means of genetic transformation using DNA isolated by the phenol-benzoate method of Kelly. Markers of this group controlling the regulation of riboflavin biosynthesis were mapped in the terminal region of the chromosome between phe and lys markers. A maximal value of contransfer index between ribC 1 and lys42 markers was found to be 3.5%.
