Drosophila brca2 is required for mitotic and meiotic DNA repair and efficient activation of the meiotic recombination checkpoint.

PLoS Genetics, 2008
Heterozygous mutations in the tumor suppressor BRCA2 confer a high risk of breast and other cancers in humans. BRCA2 maintains genome stability in part through the regulation of Rad51-dependent homologous recombination. Much about its precise function in

Manipulation of Meiotic Recombination to Hasten Crop Improvement

Biology, 2022
Reciprocal (cross-overs = COs) and non-reciprocal (gene conversion) DNA exchanges between the parental chromosomes (the homologs) during meiotic recombination are, together with mutation, the drivers for the evolution and adaptation of species.

The PHD finger protein Spp1 has distinct functions in the Set1 and the meiotic DSB formation complexes. [PDF]

PLoS Genetics, 2018
Histone H3K4 methylation is a feature of meiotic recombination hotspots shared by many organisms including plants and mammals. Meiotic recombination is initiated by programmed double-strand break (DSB) formation that in budding yeast takes place in gene ...

Shu complex SWS1-SWSAP1 promotes early steps in mouse meiotic recombination

Nature Communications, 2018
Homologous recombination ensures genome integrity during meiotic recombination. Here the authors reveal that factors SWS1 and SWSAP1 are critical for meiotic homologues recombination, particularly in promoting assembly of RAD51 and DMC1 on early ...

Separation of DNA replication from the assembly of break-competent meiotic chromosomes. [PDF]

PLoS Genetics, 2012
The meiotic cell division reduces the chromosome number from diploid to haploid to form gametes for sexual reproduction. Although much progress has been made in understanding meiotic recombination and the two meiotic divisions, the processes leading up ...

High-resolution genotyping and mapping of recombination and gene conversion in the protozoan Theileria parva using whole genome sequencing [PDF]

, 2012
BACKGROUND: Theileria parva is a tick-borne protozoan parasite, which causes East Coast Fever, a disease of cattle in sub-Saharan Africa. Like Plasmodium falciparum, the parasite undergoes a transient diploid life-cycle stage in the gut of the arthropod ...

Expression of the bacterial recA gene impairs genetic recombination and sporulation in a Saccharomyces cerevisiae diploid strain

Genetics and Molecular Biology, 2003
The Escherichia coli RecA protein (RecAp) has been demonstrated to induce mutagenesis in yeast cells, although there is still little information on the role of the RecAp in yeast recombination events.

The conserved AAA ATPase PCH-2 distributes its regulation of meiotic prophase events through multiple meiotic HORMADs in C. elegans.

PLoS Genetics, 2023
During meiotic prophase, the essential events of homolog pairing, synapsis, and recombination are coordinated with meiotic progression to promote fidelity and prevent aneuploidy.

Initiation of Meiotic Recombination in Mammals [PDF]

Genes, 2010
Meiotic recombination is initiated by the induction of programmed DNA double strand breaks (DSBs). DSB repair promotes homologous interactions and pairing and leads to the formation of crossovers (COs), which are required for the proper reductional segregation at the first meiotic division.

Apoptosis in mouse fetal and neonatal oocytes during meiotic prophase one [PDF]

, 2007
Background The vast majority of oocytes formed in the fetal ovary do not survive beyond birth. Possible reasons for their loss include the elimination of non-viable genetic constitutions arising through meiosis, however, the ...
