| Abstract: | Summary Seven mutations leading to riboflavin overproduction inBacillus subtilis were found to be linked to the markerdnaF133 (145° on theB. subtilis genetic map) by transformation. Cotransfer indexes (42.5%–61.7%) suggest that theribC 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. |
