Genome-wide recombination variation in biparental segregating and reciprocal backcross populations provides information for introgression breeding in Brassica napus

open access: yesCrop Journal, 2023
Variation in patterns of recombination in plant genomes provides information about species evolution, genetic diversity and crop improvement. We investigated meiotic crossovers generated in biparental segregating and reciprocal backcross populations of ...

Eukaryotes arose after genetic recombination [PDF]

open access: yesArchive of Oncology, 2006
Division of ancestral prokaryotic pragenome into two circular double-stranded DNA molecules by genetic recombination, is a base for future separate evolution of nuclear and mitochondrial gene compartment.

Genetic variants in REC8, RNF212, and PRDM9 influence male recombination in cattle. [PDF]

open access: yesPLoS Genetics, 2012
We use >250,000 cross-over events identified in >10,000 bovine sperm cells to perform an extensive characterization of meiotic recombination in male cattle.

SUMOylation of Rad52-Rad59 synergistically change the outcome of mitotic recombination [PDF]

open access: yes, 2016
Homologous recombination (HR) is essential for maintenance of genome stability through double-strand break (DSB) repair, but at the same time HR can lead to loss of heterozygosity and uncontrolled recombination can be genotoxic.

Recombination and Genetic Diversity

open access: yesTrends in Computational and Applied Mathematics, 2012
In this paper we present a spatial stochastic model for genetic recombination, that answers if diversity is preserved in an infinite population of recombinating individuals distributed spatially.

Genetic variation in recombination rate in the pig

open access: yesGenetics Selection Evolution, 2021
Background Meiotic recombination results in the exchange of genetic material between homologous chromosomes. Recombination rate varies between different parts of the genome, between individuals, and is influenced by genetics.

Variation and genetic control of individual recombination rates in Norwegian Red dairy cattle

open access: yesJournal of Dairy Science, 2023
: Meiotic recombination is an important evolutionary mechanism that breaks up linkages between loci and creates novel haplotypes for selection to act upon.

The effects of recombination rate on the distribution and abundance of transposable elements [PDF]

open access: yes, 2008
Transposable elements (TEs) often accumulate in regions of the genome with suppressed recombination. But it is unclear whether this pattern reflects a reduction in the efficacy of selection against deleterious insertions or a relaxation of ectopic ...

Multilocus sequence analysis of xanthomonads causing bacterial spot of tomato and pepper plants reveals strains generated by recombination among species and recent global spread of Xanthomonas gardneri [PDF]

open access: yes, 2015
Four Xanthomonas species are known to cause bacterial spot of tomato and pepper, but the global distribution and genetic diversity of these species are not well understood.
