Lineage specific recombination rates and microevolution in Listeria monocytogenes [PDF]

, 2008
Background: The bacterium Listeria monocytogenes is a saprotroph as well as an opportunistic human foodborne pathogen, which has previously been shown to consist of at least two widespread lineages (termed lineages I and II) and an uncommon lineage ...

A high-resolution map of non-crossover events reveals impacts of genetic diversity on mammalian meiotic recombination

Nature Communications, 2018
During meiotic recombination, homologue-templated repair of programmed DNA double-strand breaks (DSBs) produces relatively few crossovers and many difficult-to-detect non-crossovers.

Recombination in enteroviruses is a biphasic replicative process involving the generation of greater-than genome length 'imprecise' intermediates [PDF]

, 2014
Recombination in enteroviruses provides an evolutionary mechanism for acquiring extensive regions of novel sequence, is suggested to have a role in genotype diversity and is known to have been key to the emergence of novel neuropathogenic variants of ...

Refined genetic maps reveal sexual dimorphism in human meiotic recombination at multiple scales

Nature Communications, 2017
In humans, males have lower recombination rates than females over the majority of the genome, but the opposite is usually true near the telomeres. These broad-scale differences have been known for decades, yet little is known about differences at the ...

Mapping of meiotic recombination in human preimplantation blastocysts

G3: Genes, Genomes, Genetics, 2023
Recombination is essential for physical attachments and genetic diversity. The Han Chinese population is the largest ethnic group worldwide, therefore, the construction of a genetic map regarding recombination for the population is essential.

The genetic architecture of genome‐wide recombination rate variation in allopolyploid wheat revealed by nested association mapping

The Plant Journal, 2018
Summary Recombination affects the fate of alleles in populations by imposing constraints on the reshuffling of genetic information. Understanding the genetic basis of these constraints is critical for manipulating the recombination process to improve the

Regional differences in recombination hotspots between two chicken populations [PDF]

, 2010
Background Although several genetic linkage maps of the chicken genome have been published, the resolution of these maps is limited and does not allow the precise identification of recombination hotspots. The availability of more than 3.2 million SNPs in

Targeted recombination of homologous chromosomes using CRISPR‐Cas9

FEBS Open Bio, 2023
CRISPR mutagenesis is an efficient way to disrupt specific target genes in many model organisms. We previously devised a targeted CRISPR recombination method to generate intragenic recombinants of alleles in Drosophila.

Allopolyploidization increases genetic recombination in the ancestral diploid D genome during wheat evolution

Crop Journal, 2022
Genetic recombination produces new allelic combinations, thereby introducing variation for domestication. Allopolyploidization has increased the evolutionary potential of hexaploid common wheat by conferring the advantages of heterosis and gene ...

Linkage disequilibrium and recombination rate estimates in the self-incompatibility region of Arabidopsis lyrata [PDF]

, 2007
Genetic diversity is unusually high at loci in the S-locus region of the self-incompatible species of the flowering plant, Arabidopsis lyrata, not just in the S loci themselves, but also at two nearby loci.
