    Comparison of fine-scale recombination rates in humans and chimpanzees (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-02-12
    Description: We compared fine-scale recombination rates at orthologous loci in humans and chimpanzees by analyzing polymorphism data in both species. Strong statistical evidence for hotspots of recombination was obtained in both species. Despite approximately 99% identity at the level of DNA sequence, however, recombination hotspots were found rarely (if at all) at the same positions in the two species, and no correlation was observed in estimates of fine-scale recombination rates. Thus, local patterns of recombination rate have evolved rapidly, in a manner disproportionate to the change in DNA sequence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winckler, Wendy -- Myers, Simon R -- Richter, Daniel J -- Onofrio, Robert C -- McDonald, Gavin J -- Bontrop, Ronald E -- McVean, Gilean A T -- Gabriel, Stacey B -- Reich, David -- Donnelly, Peter -- Altshuler, David -- New York, N.Y. -- Science. 2005 Apr 1;308(5718):107-11.

    The fine-scale structure of recombination rate variation in the human genome (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-24
    Description: The nature and scale of recombination rate variation are largely unknown for most species. In humans, pedigree analysis has documented variation at the chromosomal level, and sperm studies have identified specific hotspots in which crossing-over events cluster. To address whether this picture is representative of the genome as a whole, we have developed and validated a method for estimating recombination rates from patterns of genetic variation. From extensive single-nucleotide polymorphism surveys in European and African populations, we find evidence for extreme local rate variation spanning four orders in magnitude, in which 50% of all recombination events take place in less than 10% of the sequence. We demonstrate that recombination hotspots are a ubiquitous feature of the human genome, occurring on average every 200 kilobases or less, but recombination occurs preferentially outside genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McVean, Gilean A T -- Myers, Simon R -- Hunt, Sarah -- Deloukas, Panos -- Bentley, David R -- Donnelly, Peter -- New York, N.Y. -- Science. 2004 Apr 23;304(5670):581-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Statistics, University of Oxford, Oxford OX1 3TG, UK. mcvean@stats.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15105499" target="_blank"〉PubMed〈/a〉

    The landscape of recombination in African Americans (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-07-22
    Description: Recombination, together with mutation, gives rise to genetic variation in populations. Here we leverage the recent mixture of people of African and European ancestry in the Americas to build a genetic map measuring the probability of crossing over at each position in the genome, based on about 2.1 million crossovers in 30,000 unrelated African Americans. At intervals of more than three megabases it is nearly identical to a map built in Europeans. At finer scales it differs significantly, and we identify about 2,500 recombination hotspots that are active in people of West African ancestry but nearly inactive in Europeans. The probability of a crossover at these hotspots is almost fully controlled by the alleles an individual carries at PRDM9 (P value 〈 10(-245)). We identify a 17-base-pair DNA sequence motif that is enriched in these hotspots, and is an excellent match to the predicted binding target of PRDM9 alleles common in West Africans and rare in Europeans. Sites of this motif are predicted to be risk loci for disease-causing genomic rearrangements in individuals carrying these alleles. More generally, this map provides a resource for research in human genetic variation and evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154982/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154982/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hinch, Anjali G -- Tandon, Arti -- Patterson, Nick -- Song, Yunli -- Rohland, Nadin -- Palmer, Cameron D -- Chen, Gary K -- Wang, Kai -- Buxbaum, Sarah G -- Akylbekova, Ermeg L -- Aldrich, Melinda C -- Ambrosone, Christine B -- Amos, Christopher -- Bandera, Elisa V -- Berndt, Sonja I -- Bernstein, Leslie -- Blot, William J -- Bock, Cathryn H -- Boerwinkle, Eric -- Cai, Qiuyin -- Caporaso, Neil -- Casey, Graham -- Cupples, L Adrienne -- Deming, Sandra L -- Diver, W Ryan -- Divers, Jasmin -- Fornage, Myriam -- Gillanders, Elizabeth M -- Glessner, Joseph -- Harris, Curtis C -- Hu, Jennifer J -- Ingles, Sue A -- Isaacs, William -- John, Esther M -- Kao, W H Linda -- Keating, Brendan -- Kittles, Rick A -- Kolonel, Laurence N -- Larkin, Emma -- Le Marchand, Loic -- McNeill, Lorna H -- Millikan, Robert C -- Murphy, Adam -- Musani, Solomon -- Neslund-Dudas, Christine -- Nyante, Sarah -- Papanicolaou, George J -- Press, Michael F -- Psaty, Bruce M -- Reiner, Alex P -- Rich, Stephen S -- Rodriguez-Gil, Jorge L -- Rotter, Jerome I -- Rybicki, Benjamin A -- Schwartz, Ann G -- Signorello, Lisa B -- Spitz, Margaret -- Strom, Sara S -- Thun, Michael J -- Tucker, Margaret A -- Wang, Zhaoming -- Wiencke, John K -- Witte, John S -- Wrensch, Margaret -- Wu, Xifeng -- Yamamura, Yuko -- Zanetti, Krista A -- Zheng, Wei -- Ziegler, Regina G -- Zhu, Xiaofeng -- Redline, Susan -- Hirschhorn, Joel N -- Henderson, Brian E -- Taylor, Herman A Jr -- Price, Alkes L -- Hakonarson, Hakon -- Chanock, Stephen J -- Haiman, Christopher A -- Wilson, James G -- Reich, David -- Myers, Simon R -- 090532/Wellcome Trust/United Kingdom -- CA060691/CA/NCI NIH HHS/ -- CA092447/CA/NCI NIH HHS/ -- CA100374/CA/NCI NIH HHS/ -- CA100598/CA/NCI NIH HHS/ -- CA1116460/CA/NCI NIH HHS/ -- CA1116460S1/CA/NCI NIH HHS/ -- CA121197/CA/NCI NIH HHS/ -- CA121197S2/CA/NCI NIH HHS/ -- CA127219/CA/NCI NIH HHS/ -- CA1326792/CA/NCI NIH HHS/ -- CA140388/CA/NCI NIH HHS/ -- CA141716/CA/NCI NIH HHS/ -- CA148085/CA/NCI NIH HHS/ -- CA148127/CA/NCI NIH HHS/ -- CA22453/CA/NCI NIH HHS/ -- CA54281/CA/NCI NIH HHS/ -- CA55769/CA/NCI NIH HHS/ -- CA58223/CA/NCI NIH HHS/ -- CA63464/CA/NCI NIH HHS/ -- CA68485/CA/NCI NIH HHS/ -- CA68578/CA/NCI NIH HHS/ -- CA77305/CA/NCI NIH HHS/ -- CA87895/CA/NCI NIH HHS/ -- CA88164/CA/NCI NIH HHS/ -- ES007784/ES/NIEHS NIH HHS/ -- ES011126/ES/NIEHS NIH HHS/ -- ES06717/ES/NIEHS NIH HHS/ -- ES10126/ES/NIEHS NIH HHS/ -- GM08016/GM/NIGMS NIH HHS/ -- GM091332/GM/NIGMS NIH HHS/ -- HD33175/HD/NICHD NIH HHS/ -- HG004726/HG/NHGRI NIH HHS/ -- HHSN268200960009C/PHS HHS/ -- HL084107/HL/NHLBI NIH HHS/ -- N01-HC-65226/HC/NHLBI NIH HHS/ -- P30 ES010126/ES/NIEHS NIH HHS/ -- R01 CA052689/CA/NCI NIH HHS/ -- R01 CA092447/CA/NCI NIH HHS/ -- R01 HG006399/HG/NHGRI NIH HHS/ -- R01 HL084107-04/HL/NHLBI NIH HHS/ -- R01-CA73629/CA/NCI NIH HHS/ -- U01 HG004168/HG/NHGRI NIH HHS/ -- U01 HG004168-03/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2011 Jul 20;476(7359):170-5. doi: 10.1038/nature10336.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Human Genetics, Oxford University, Roosevelt Drive, Oxford OX3 7BN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21775986" target="_blank"〉PubMed〈/a〉

    Re-engineering the zinc fingers of PRDM9 reverses hybrid sterility in mice (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-02-04
    Description: The DNA-binding protein PRDM9 directs positioning of the double-strand breaks (DSBs) that initiate meiotic recombination in mice and humans. Prdm9 is the only mammalian speciation gene yet identified and is responsible for sterility phenotypes in male hybrids of certain mouse subspecies. To investigate PRDM9 binding and its role in fertility and meiotic recombination, we humanized the DNA-binding domain of PRDM9 in C57BL/6 mice. This change repositions DSB hotspots and completely restores fertility in male hybrids. Here we show that alteration of one Prdm9 allele impacts the behaviour of DSBs controlled by the other allele at chromosome-wide scales. These effects correlate strongly with the degree to which each PRDM9 variant binds both homologues at the DSB sites it controls. Furthermore, higher genome-wide levels of such 'symmetric' PRDM9 binding associate with increasing fertility measures, and comparisons of individual hotspots suggest binding symmetry plays a downstream role in the recombination process. These findings reveal that subspecies-specific degradation of PRDM9 binding sites by meiotic drive, which steadily increases asymmetric PRDM9 binding, has impacts beyond simply changing hotspot positions, and strongly support a direct involvement in hybrid infertility. Because such meiotic drive occurs across mammals, PRDM9 may play a wider, yet transient, role in the early stages of speciation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4756437/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4756437/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davies, Benjamin -- Hatton, Edouard -- Altemose, Nicolas -- Hussin, Julie G -- Pratto, Florencia -- Zhang, Gang -- Hinch, Anjali Gupta -- Moralli, Daniela -- Biggs, Daniel -- Diaz, Rebeca -- Preece, Chris -- Li, Ran -- Bitoun, Emmanuelle -- Brick, Kevin -- Green, Catherine M -- Camerini-Otero, R Daniel -- Myers, Simon R -- Donnelly, Peter -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 095552/Z/11/Z/Wellcome Trust/United Kingdom -- 098387/Z/12/Z/Wellcome Trust/United Kingdom -- Intramural NIH HHS/ -- England -- Nature. 2016 Feb 11;530(7589):171-6. doi: 10.1038/nature16931.

    Relative Surface-wave Amplitude and Phase Anomalies from the Democratic People's Republic Korea Announced Nuclear Tests (2017)
    Wiley
    Details
    Publication Date: 2017-08-31
    Description: We performed relative locations of six event-pairs based on surface-wave (SW) and body-wave (BW) differential travel-times of the 2016-09-09, 2016-01-06, 2013-02-12, and 2009-05-25 announced North Korea nuclear explosions. The SW relative locations for the 2009-05-25 and 2013-02-12 events were inconsistent with the BWs when paired with other events and only the 2016-01-06/2016-09-09 pair was consistent. Apparent SW phase shift is investigated with respect to the BW relative locations. The pairs formed with the 2009-05-25 and 2013-02-12 events, beneath the southeast slope of Mount Mant'ap, have the largest phase shifts and amplitude ratio deviations, whereas the least deviation was from the 2016-01-06 and 2016-09-09 event-pair beneath the mountain peak. Regional moment tensors (MTs) predict the amplitude ratios but do not resolve the relative phase. We find MTs with 10% difference in isotropic and rotated +CLVD can fit both relative phase and amplitude ratios. SW relative locations of highly isotropic and correlated explosion clusters can be affected by topography and small differences in MT.
