TranscriptomicsRec8 guides canonical Spo11 distribution along yeast meiotic chromosomes
Spo11-mediated DNA double strand breaks (DSBs) that initiate meiotic recombination are temporally and spatially controlled. The meiotic cohesin Rec8 has been implicated in regulating DSB formation, but little is known about the features of their interplay. To shed light on this point, we investigate...

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...

GenomicsMeiotic recombination initiation hotspots in Arabidopsis genes and transposons (SPO11-1-oligonucleotides-seq)
To determine meiotic recombination initiation sites in Arabidopsis thaliana genome we purified and sequenced oligonucleotides (35-45 nt) bound to SPO11-1, meiosis specific transesterase that induces meiotic DSB formation. This reveals that SPO11-1-oligonucleotide hotspots occur at nucleosome deplete...

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...

TranscriptomicsSpo11-oligo mapping in zip3 mutants
Meiotic recombination promotes genetic diversification as well as pairing and segregation of homologous chromosomes, but the double-strand breaks (DSBs) that initiate recombination are dangerous lesions that can cause mutation or meiotic failure. How cells control DSBs to balance between beneficial ...

GenomicsMeiotic recombination cold spots in chromosomal cohesion sites [ChIP-Seq]
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...

GenomicsSpo11-oligo mapping in bas1 and ino4 mutants
Meiotic recombination is initiated by developmentally programmed DNA double-strand breaks (DSBs). In S. cerevisiae, the vast majority of DSBs occur in the nucleosome-depleted regions at gene promoters, where transcription factors (TFs) bind. It has been proposed that TF binding can stimulate DSB for...
