Escherichia coli mutM suppresses illegitimate recombination induced by oxidative stress.
DNA damage by oxidative stress is one of the causes of mutagenesis. However, whether or not DNA damage induces illegitimate recombination has not been determined. To study the effect of oxidative stress on illegitimate recombination, we examined the frequency of lambdabio transducing phage in the presence of hydrogen peroxide and found that this reagent enhances illegitimate recombination. To c...
متن کاملStress-induced intrachromosomal recombination in plant somatic cells.
Levels of induced homologous recombination between chromosomal repeats in plant somatic cells were examined. Transgenic plants of Nicotiana tabacum hemi- or homozygous for pairs of deletion derivatives of the neomycin phosphotransferase (nptII) marker gene integrated at a single genomic locus were produced. Homologous recombination within the overlapping parts of the nptII gene restored the fun...
متن کاملRecombination induced hypergraphs: A new approach to mutation-recombination isomorphism
Natural selection acts on genetic variation that comes from two principal sources: mutation and recombination. Because of the inherent differences between mutation and recombination, it is often assumed that they are qualitatively different ways to explore the genotype space. In this paper a new way of constructing recombination spaces is introduced and the topological features of the resulting...
متن کاملGenetic Recombination in Dna-induced Transformation
HE science of genetics has undergone a tremendous development as a result T of the discovery of novel systems of exchange of genetic material. The first new system to be discovered was that of DNA-induced bacterial transformation (AVERY, MACLEOD and MCCARTY 1944) , yet as a purely genetic tool this system has been little used, in spite of possessing unique experimental possibilities. The presen...
متن کاملMating-induced recombination in fruit flies.
In traditional deterministic models the conditions for the evolution of sex and sexual behavior are limited because their benefits are context dependent. In novel and adverse environments both multiple mating and recombination can help generate gene combinations that allow for rapid adaptation. Mating frequency often increases in conditions in which recombination might be beneficial; therefore,...
