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.

A Correlation of Cytological and Genetical Crossing-Over in Zea Mays [PDF]
Proceedings of the National Academy of Sciences, 1931 In this paper, McClintock and Creighton conclusively demonstrated the occurrence of genetic and cytological crossingover, a process assumed but not proven since 1910. In it they took two genetic markers and two cytological markers and demonstrated that when crossing-over occurred, they traveled together.

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 BiologyThe 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.

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

The Correlation of Cytological and Genetical Crossing-Over in Zea Mays. A Corroboration [PDF]
Proceedings of the National Academy of Sciences, 1935 In this article, McClintock and Creighton addressed critics who felt their 1931 paper did not have enough data by corroborating their earlier findings on crossing-over.

Natural genetic transformation generates a population of merodiploids in Streptococcus pneumoniae. [PDF]
PLoS Genetics, 2013 Partial duplication of genetic material is prevalent in eukaryotes and provides potential for evolution of new traits. Prokaryotes, which are generally haploid in nature, can evolve new genes by partial chromosome duplication, known as merodiploidy ...

A high-resolution crossover landscape in Drosophila santomea reveals rapid and concerted evolution of multiple properties of crossing over control. [PDF]
PLoS GenetCrossing over is a fundamental process in sexually reproducing species, ensuring proper chromosome segregation during gamete formation and generating new allelic combinations that enhance adaptation. Despite its essential role, genes involved in crossing
