  • Published 2003
Using a direct enrichment and screening procedure, mutants of Escherichia coli have been isolated in which recombination frequencies for several intragenic Hfr X Fcrosses are significantly higher (twofold to sixfold) than in the parental strains. These hyper-recombination mutations comprised five new m u t S and one new mutLallele. Together with other known mutalleles, they were analyzed for effects on intragenic recombination using several types of crosses. Hyperrecombination was found for… CONTINUE READING
