Senataxin plays an essential role with DNA damage response proteins in meiotic recombination and gene silencing. [PDF]

PLoS Genetics, 2013
Senataxin, mutated in the human genetic disorder ataxia with oculomotor apraxia type 2 (AOA2), plays an important role in maintaining genome integrity by coordination of transcription, DNA replication, and the DNA damage response.

Widespread gene conversion in centromere cores. [PDF]

PLoS Biology, 2010
Centromeres are the most dynamic regions of the genome, yet they are typified by little or no crossing over, making it difficult to explain the origin of this diversity.

Meiotic recombination in Arabidopsis is catalysed by DMC1, with RAD51 playing a supporting role. [PDF]

PLoS Genetics, 2013
Recombination establishes the chiasmata that physically link pairs of homologous chromosomes in meiosis, ensuring their balanced segregation at the first meiotic division and generating genetic variation.

Genetic variability in soybean with resistance to cyst nematode and powdery mildew: impact of multi-parent crosses on recombination and genetic diversity [PDF]

Brazilian Journal of Biology
The objective of this study was to analyze the genetic variability generated from two-way, four-way, and eight-way hybridizations in soybean, derived from parental lines contrasting in resistance to cyst nematode and powdery mildew.

Genome-Wide Association Study and Subsequent Exclusion of ATCAY as a Candidate Gene Involved in Equine Neuroaxonal Dystrophy Using Two Animal Models. [PDF]

, 2020
Equine neuroaxonal dystrophy/equine degenerative myeloencephalopathy (eNAD/EDM) is an inherited neurodegenerative disorder of unknown etiology. Clinical signs of neurological deficits develop within the first year of life in vitamin E (vitE) deficient ...

Inversions in the third chromosome of wild races of Drosophila pseudoobscura, and their use in the study of the history of the species [PDF]

, 1936
Genetic studies showed several years ago that the third chromosomes of wild strains of Drosophila pseudoobscura often carry suppressors of crossing-over.

Regulated Proteolysis of MutSγ Controls Meiotic Crossing Over.

Molecules and Cells, 2020
Crossover recombination is essential for accurate chromosome segregation during meiosis. The MutSγ complex, Msh4-Msh5, facilitates crossing over by binding and stabilizing nascent recombination intermediates. We show that these activities are governed by

Comparative gene mapping in Arabidopsis lyrata chromosomes 1 and 2 and the corresponding A. thaliana chromosome 1: recombination rates, rearrangements and centromere location [PDF]

, 2006
To add detail to the genetic map of Arabidopsis lyrata, and compare it with that of A. thaliana, we have developed many additional markers in the A. lyrata linkage groups, LG1 and LG2, corresponding to A. thaliana chromosome 1.

Positive Selection and Functional Divergence at Meiosis Genes That Mediate Crossing Over Across the Drosophila Phylogeny

G3: Genes, Genomes, Genetics, 2019
Meiotic crossing over ensures proper segregation of homologous chromosomes and generates genotypic diversity. Despite these functions, little is known about the genetic factors and population genetic forces involved in the evolution of recombination rate
