DOI: 10.1038/s41598-018-23508-x
Abstract: Several evolutionary mechanisms alter the fate of mutations and genes within populations based on their exhibited functional effects. To understand the underlying mechanisms involved in the evolution of the cellular stress response, a very conserved… read more here.

DOI: 10.1093/hmg/ddac144
Abstract: The human MSY ampliconic region is mainly composed of large duplicated sequences that are organized in eight palindromes (termed P1-P8), and may undergo arm-to-arm gene conversion. Although the importance of these elements is widely recognised,… read more here.

Strong suppression of gene conversion with increasing DNA double-strand break load delimited by 53BP1 and RAD52

DOI: 10.1093/nar/gkz1167
Abstract: Abstract In vertebrates, genomic DNA double-strand breaks (DSBs) are removed by non-homologous end-joining processes: classical non-homologous end-joining (c-NHEJ) and alternative end-joining (alt-EJ); or by homology-dependent processes: gene-conversion (GC) and single-strand annealing (SSA). Surprisingly, these repair… read more here.

DOI: 10.1111/mec.14921
Abstract: Chromosomal inversions shape recombination landscapes, and species differing by inversions may exhibit reduced gene flow in these regions of the genome. Though single crossovers within inversions are not usually recovered from inversion heterozygotes, the recombination… read more here.

DOI: 10.1186/s12864-021-07776-y
Abstract: Background Duplicated gene pairs produced by ancient polyploidy maintain high sequence similarity over a long period of time and may result from illegitimate recombination between homeologous chromosomes. The genomes of Asian cultivated rice Oryza sativa… read more here.

DOI: 10.1534/genetics.120.303335
Abstract: Reduction of fitness due to deleterious mutations imposes a limit to adaptive evolution. By characterizing features that influence this genetic load we may better understand constraints on responses to both natural and human-mediated selection. Here,… read more here.

DOI: 10.3389/fevo.2018.00203
Abstract: It is well established that GC content varies across the genome in many species and that GC biased gene conversion, one form of meiotic recombination, is likely to contribute to this heterogeneity. Bird genomes provide… read more here.
