TranscriptomicsRecombination initiation maps of individual human genomes
DNA double-strand breaks (DSBs) are introduced in meiosis to initiate recombination and to generate crossovers, the reciprocal exchanges of genetic material between parental chromosomes. Here we present the first high-resolution map of meiotic DSBs in individual human genomes. Comparing DSB maps bet...

TranscriptomicsHistone H3 lysine9 acetylation, rather than lysine4 trimethylation, marks meiotic recombination hotspots and promotes recombination initiation in fission yeast
Histone modifications are associated with meiotic recombination hotspots, discrete sites with augmented recombination frequency. For example, trimethylation of histone H3 lysine4 (H3K4me3) marks most hotspots in budding yeast and mouse. Modified histones are known to regulate meiotic recombinatio...

TranscriptomicsMeiotic recombination cold spots in chromosomal cohesion sites [ChIP-chip]
Meiotic chromosome architecture called M-bM-^@M-^\axis-loop structuresM-bM-^@M-^] and histone modifications have been demonstrated to regulate the Spo11-dependent formation of DNA double-strand breaks (DSBs) that trigger meiotic recombination. Using genome-wide chromatin immunoprecipitation (ChIP) a...

GenomicsSupression of genetic recombination in the pseudoautosomal region and at subtelomeres in mice with a hypomorphic spo11 allele
Homologous recombination is the key process that generates genetic diversity and drives evolution. SPO11 protein triggers recombination by introducing DNA double stranded breaks at discreet areas of the genome called recombination hotspots. The hotspot locations are largely determined by the DNA bin...

TranscriptomicsMeiotic DNA double strand breaks in the yeast Saccaromyces cerevisiae
DNA double-strand breaks (DSBs) initiate meiotic recombination. Past DSB-mapping studies have used rad50S or sae2? mutants, which are defective in break processing, to accumulate DSBs, and report large (= 50 kb) “DSB-hot” regions that are separated by “DSB-cold” domains of similar size. Substantial ...

GenomicsGenome-wide mapping of meiotic double-strand breaks by sequencing Spo11 oligos.
The nonrandom distribution of meiotic recombination shapes patterns of inheritance and genome evolution, but chromosomal features governing this distribution are poorly understood. Formation of the DNA double-strand breaks (DSBs) that initiate recombination results in accumulation of Spo11 protei...

TranscriptomicsSeparation of DNA replication from the assembly of break-competent meiotic chromosomes
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 to recombination, including the prolonged pre-m...

TranscriptomicsTranscription profiling of S. cerevisiae mre11, rad50 and spo11 mutants in premeiosis and meiotic prophase
Mre11, together with Rad50 and Xrs2/NBS, plays pivotal roles in homologous recombination, repair of DNA double strand breaks (DSBs), activation of damage-induced checkpoint, and telomere maintenance. Using DNA microarray assays to analyze yeast mutants (mre11delta, rad50delta, and spo11Y135F) defect...

ProteomicsProteomic analysis of the Ade6-M26 meiotic recombination hotspot in the fission yeast schizosaccharomyces pombe
Homologous recombination events during meiosis cluster at specific loci called hotspots. Hotspot activation requires accessible chromatin, DNA sequence motifs DNA sequence-specific binding proteins, but how these proteins create a suitable environment for Rec12 recruitment is unknown. Here, we pur...
