Unequal genetic exchange in Escherichia coli tandem duplications may represent a special pathway of homologous recombination

Unequal genetic exchange in Escherichia coli tandem duplications may represent a special pathway... Heterozygous tandem duplications that appear in Escherichia coli conjugation matings segregate different types of haploid and diploid recombinants formed by unequal crossing over between sister chromosomes. As shown previously, the frequency of segregants in the extended duplication D104 (∼150 kb or more than 3 min of the genetic map) heterozygous for E. coli deo-operon genes (deoA deoB::Tn5/deoC deoD) is not decreased in strains with defective RecBCD and RecF recombination pathways. Analysis of a shorter duplication of this type (∼46 kb) showed that the frequency of segregants in the strain recBC sbcBC recF was similar to that in a strain with undamaged system of recombination. Thus, genetic exchange between direct DNA repeats in tandem duplications may follow a special pathway of homologous recombination, which is independent of the recBC and recF genes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals
