Pioneering meiotic recombination [PDF]
To induce cell type-specific forms of gene regulation, pioneer factors open tightly packed, inaccessible chromatin sites, enabling the molecular machinery to act on functionally significant information encoded in DNA. While previous studies of pioneer factors have revealed their functions in transcriptional regulation, pioneer factors that open ...

The Impressionistic Landscape of Meiotic Recombination [PDF]
Two high-resolution maps of meiotic recombination initiation sites across the genomes of budding yeast and mice illuminate broad similarities in the control of meiotic recombination in these diverse species but also highlight key differences. These studies offer new insights into the relationships between recombination, chromosome structure, and genome

Hybrid Sterility Locus on Chromosome X Controls Meiotic Recombination Rate in Mouse. [PDF]
Meiotic recombination safeguards proper segregation of homologous chromosomes into gametes, affects genetic variation within species, and contributes to meiotic chromosome recognition, pairing and synapsis.

Identification and Expression of TOP3α in Gerbera hybrida
Meiotic recombination and the resulting novel allele combinations are fundamental to plant breeding and the identification of superior hybrids. However, the rate of meiotic crossovers is naturally suppressed below its potential ability, which prevents ...

The molecular machinery of meiotic recombination. [PDF]
Meiotic recombination, a cornerstone of eukaryotic diversity and individual genetic identity, is essential for the creation of physical linkages between homologous chromosomes, facilitating their faithful segregation during meiosis I. This process requires that germ cells generate controlled DNA lesions within their own genome that are subsequently ...

Hotspots for Initiation of Meiotic Recombination [PDF]
Homologous chromosomes must pair and recombine to ensure faithful chromosome segregation during meiosis, a specialized type of cell division that occurs in sexually reproducing eukaryotes. Meiotic recombination initiates by programmed induction of DNA double-strand breaks (DSBs) by the conserved type II topoisomerase-like enzyme SPO11.

Direct and indirect control of the initiation of meiotic recombination by DNA damage checkpoint mechanisms in budding yeast [PDF]
Meiotic recombination plays an essential role in the proper segregation of chromosomes at meiosis I in many sexually reproducing organisms. Meiotic recombination is initiated by the scheduled formation of genome-wide DNA double-strand breaks (DSBs).

Background Meiotic recombination is initiated by Spo11-dependent programmed DNA double-strand breaks (DSBs) that are preferentially concentrated within genomic regions called hotspots; however, the factor(s) that specify the positions of meiotic DSB ...

Targeted Stimulation of Meiotic Recombination [PDF]
Meiotic recombination in Saccharomyces cerevisiae is initiated by programmed DNA double-strand breaks (DSBs), a process that requires the Spo11 protein. DSBs usually occur in intergenic regions that display open chromatin accessibility, but other determinants that control their frequencies and non-random chromosomal distribution remain obscure.

Meiotic recombination ensures accurate homologous chromosome segregation during meiosis and generates novel allelic combinations among gametes. During meiosis, DNA double strand breaks (DSBs) are generated to facilitate recombination.
