Description: Temporal variations of the frictional resistance on subduction-zone plate boundary faults associated with the stick-slip cycle of large interplate earthquakes are thought to modulate the stress regime and earthquake activity within the subducting oceanic plate. Here we report on two great earthquakes that occurred near the Kuril islands, which shed light on this process and demonstrate the enhanced seismic hazard accompanying triggered faulting. On 15 November 2006, an event of moment magnitude 8.3 ruptured the shallow-dipping plate boundary along which the Pacific plate descends beneath the central Kuril arc. The thrust ruptured a seismic gap that previously had uncertain seismogenic potential, although the earlier occurrence of outer-rise compressional events had suggested the presence of frictional resistance. Within minutes of this large underthrusting event, intraplate extensional earthquakes commenced in the outer rise region seaward of the Kuril trench, and on 13 January 2007, an event of moment magnitude 8.1 ruptured a normal fault extending through the upper portion of the Pacific plate, producing one of the largest recorded shallow extensional earthquakes. This energetic earthquake sequence demonstrates the stress transfer process within the subducting lithosphere, and the distinct rupture characteristics of these great earthquakes illuminate differences in seismogenic properties and seismic hazard of such interplate and intraplate faults.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ammon, Charles J -- Kanamori, Hiroo -- Lay, Thorne -- England -- Nature. 2008 Jan 31;451(7178):561-5. doi: 10.1038/nature06521.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geosciences, The Pennsylvania State University, 440 Deike Building, University Park, Pennsylvania 16802, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18235499" target="_blank"〉PubMed〈/a〉

Description: Great earthquakes (having seismic magnitudes of at least 8) usually involve abrupt sliding of rock masses at a boundary between tectonic plates. Such interplate ruptures produce dynamic and static stress changes that can activate nearby intraplate aftershocks, as is commonly observed in the trench-slope region seaward of a great subduction zone thrust event. The earthquake sequence addressed here involves a rare instance in which a great trench-slope intraplate earthquake triggered extensive interplate faulting, reversing the typical pattern and broadly expanding the seismic and tsunami hazard. On 29 September 2009, within two minutes of the initiation of a normal faulting event with moment magnitude 8.1 in the outer trench-slope at the northern end of the Tonga subduction zone, two major interplate underthrusting subevents (both with moment magnitude 7.8), with total moment equal to a second great earthquake of moment magnitude 8.0, ruptured the nearby subduction zone megathrust. The collective faulting produced tsunami waves with localized regions of about 12 metres run-up that claimed 192 lives in Samoa, American Samoa and Tonga. Overlap of the seismic signals obscured the fact that distinct faults separated by more than 50 km had ruptured with different geometries, with the triggered thrust faulting only being revealed by detailed seismic wave analyses. Extensive interplate and intraplate aftershock activity was activated over a large region of the northern Tonga subduction zone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lay, Thorne -- Ammon, Charles J -- Kanamori, Hiroo -- Rivera, Luis -- Koper, Keith D -- Hutko, Alexander R -- England -- Nature. 2010 Aug 19;466(7309):964-8. doi: 10.1038/nature09214.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Sciences, University of California Santa Cruz, Santa Cruz, California 95064, USA. tlay@ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20725038" target="_blank"〉PubMed〈/a〉

Description: For 10,000 years pigs and humans have shared a close and complex relationship. From domestication to modern breeding practices, humans have shaped the genomes of domestic pigs. Here we present the assembly and analysis of the genome sequence of a female domestic Duroc pig (Sus scrofa) and a comparison with the genomes of wild and domestic pigs from Europe and Asia. Wild pigs emerged in South East Asia and subsequently spread across Eurasia. Our results reveal a deep phylogenetic split between European and Asian wild boars approximately 1 million years ago, and a selective sweep analysis indicates selection on genes involved in RNA processing and regulation. Genes associated with immune response and olfaction exhibit fast evolution. Pigs have the largest repertoire of functional olfactory receptor genes, reflecting the importance of smell in this scavenging animal. The pig genome sequence provides an important resource for further improvements of this important livestock species, and our identification of many putative disease-causing variants extends the potential of the pig as a biomedical model.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3566564/" 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/PMC3566564/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Groenen, Martien A M -- Archibald, Alan L -- Uenishi, Hirohide -- Tuggle, Christopher K -- Takeuchi, Yasuhiro -- Rothschild, Max F -- Rogel-Gaillard, Claire -- Park, Chankyu -- Milan, Denis -- Megens, Hendrik-Jan -- Li, Shengting -- Larkin, Denis M -- Kim, Heebal -- Frantz, Laurent A F -- Caccamo, Mario -- Ahn, Hyeonju -- Aken, Bronwen L -- Anselmo, Anna -- Anthon, Christian -- Auvil, Loretta -- Badaoui, Bouabid -- Beattie, Craig W -- Bendixen, Christian -- Berman, Daniel -- Blecha, Frank -- Blomberg, Jonas -- Bolund, Lars -- Bosse, Mirte -- Botti, Sara -- Bujie, Zhan -- Bystrom, Megan -- Capitanu, Boris -- Carvalho-Silva, Denise -- Chardon, Patrick -- Chen, Celine -- Cheng, Ryan -- Choi, Sang-Haeng -- Chow, William -- Clark, Richard C -- Clee, Christopher -- Crooijmans, Richard P M A -- Dawson, Harry D -- Dehais, Patrice -- De Sapio, Fioravante -- Dibbits, Bert -- Drou, Nizar -- Du, Zhi-Qiang -- Eversole, Kellye -- Fadista, Joao -- Fairley, Susan -- Faraut, Thomas -- Faulkner, Geoffrey J -- Fowler, Katie E -- Fredholm, Merete -- Fritz, Eric -- Gilbert, James G R -- Giuffra, Elisabetta -- Gorodkin, Jan -- Griffin, Darren K -- Harrow, Jennifer L -- Hayward, Alexander -- Howe, Kerstin -- Hu, Zhi-Liang -- Humphray, Sean J -- Hunt, Toby -- Hornshoj, Henrik -- Jeon, Jin-Tae -- Jern, Patric -- Jones, Matthew -- Jurka, Jerzy -- Kanamori, Hiroyuki -- Kapetanovic, Ronan -- Kim, Jaebum -- Kim, Jae-Hwan -- Kim, Kyu-Won -- Kim, Tae-Hun -- Larson, Greger -- Lee, Kyooyeol -- Lee, Kyung-Tai -- Leggett, Richard -- Lewin, Harris A -- Li, Yingrui -- Liu, Wansheng -- Loveland, Jane E -- Lu, Yao -- Lunney, Joan K -- Ma, Jian -- Madsen, Ole -- Mann, Katherine -- Matthews, Lucy -- McLaren, Stuart -- Morozumi, Takeya -- Murtaugh, Michael P -- Narayan, Jitendra -- Nguyen, Dinh Truong -- Ni, Peixiang -- Oh, Song-Jung -- Onteru, Suneel -- Panitz, Frank -- Park, Eung-Woo -- Park, Hong-Seog -- Pascal, Geraldine -- Paudel, Yogesh -- Perez-Enciso, Miguel -- Ramirez-Gonzalez, Ricardo -- Reecy, James M -- Rodriguez-Zas, Sandra -- Rohrer, Gary A -- Rund, Lauretta -- Sang, Yongming -- Schachtschneider, Kyle -- Schraiber, Joshua G -- Schwartz, John -- Scobie, Linda -- Scott, Carol -- Searle, Stephen -- Servin, Bertrand -- Southey, Bruce R -- Sperber, Goran -- Stadler, Peter -- Sweedler, Jonathan V -- Tafer, Hakim -- Thomsen, Bo -- Wali, Rashmi -- Wang, Jian -- Wang, Jun -- White, Simon -- Xu, Xun -- Yerle, Martine -- Zhang, Guojie -- Zhang, Jianguo -- Zhang, Jie -- Zhao, Shuhong -- Rogers, Jane -- Churcher, Carol -- Schook, Lawrence B -- 095908/Wellcome Trust/United Kingdom -- 249894/European Research Council/International -- 5 P41 LM006252/LM/NLM NIH HHS/ -- 5 P41LM006252/LM/NLM NIH HHS/ -- BB/E010520/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E010520/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E010768/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E011640/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G004013/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/H005935/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I025328/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0900950/Medical Research Council/United Kingdom -- P20-RR017686/RR/NCRR NIH HHS/ -- P30 DA018310/DA/NIDA NIH HHS/ -- R13 RR020283A/RR/NCRR NIH HHS/ -- R13 RR032267A/RR/NCRR NIH HHS/ -- R21 DA027548/DA/NIDA NIH HHS/ -- R21 HG006464/HG/NHGRI NIH HHS/ -- T32 AI083196/AI/NIAID NIH HHS/ -- England -- Nature. 2012 Nov 15;491(7424):393-8. doi: 10.1038/nature11622.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Animal Breeding and Genomics Centre, Wageningen University, De Elst 1, 6708 WD, Wageningen, The Netherlands. martien.groenen@wur.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23151582" target="_blank"〉PubMed〈/a〉

Description: The establishment of a complete genomic sequence of silkworm, the model species of Lepidoptera, laid a foundation for its functional genomics. A more complete annotation of the genome will benefit functional and comparative studies and accelerate extensive industrial applications for this insect. To realize these goals, we embarked upon a large-scale full-length cDNA collection from 21 full-length cDNA libraries derived from 14 tissues of the domesticated silkworm and performed full sequencing by primer walking for 11,104 full-length cDNAs. The large average intron size was 1904 bp, resulting from a high accumulation of transposons. Using gene models predicted by GLEAN and published mRNAs, we identified 16,823 gene loci on the silkworm genome assembly. Orthology analysis of 153 species, including 11 insects, revealed that among three Lepidoptera including Monarch and Heliconius butterflies, the 403 largest silkworm-specific genes were composed mainly of protective immunity, hormone-related, and characteristic structural proteins. Analysis of testis-/ovary-specific genes revealed distinctive features of sexual dimorphism, including depletion of ovary-specific genes on the Z chromosome in contrast to an enrichment of testis-specific genes. More than 40% of genes expressed in specific tissues mapped in tissue-specific chromosomal clusters. The newly obtained FL-cDNA sequences enabled us to annotate the genome of this lepidopteran model insect more accurately, enhancing genomic and functional studies of Lepidoptera and comparative analyses with other insect orders, and yielding new insights into the evolution and organization of lepidopteran-specific genes.

Description: Upon wounding or pathogen invasion, leaves of sorghum [ Sorghum bicolor (L.) Moench] plants with the P gene turn purple, whereas leaves with the recessive allele turn brown or tan. This purple phenotype is determined by the production of two 3-deoxyanthocyanidins, apigeninidin and luteolinidin, which are not produced by the tan-phenotype plants. Using map-based cloning in progeny from a cross between purple Nakei-MS3B ( PP ) and tan Greenleaf ( pp ) cultivars, we isolated this gene, which was located in a 27-kb genomic region around the 58.1 Mb position on chromosome 6. Four candidate genes identified in this region were similar to the maize leucoanthocyanidin reductase gene. None of them was expressed before wounding, and only the Sb06g029550 gene was induced in both cultivars after wounding. The Sb06g029550 protein was detected in Nakei-MS3B, but only slightly in Greenleaf, in which it may be unstable because of a Cys252Tyr substitution. A recombinant Sb06g029550 protein had a specific flavanone 4-reductase activity, and converted flavanones (naringenin or eriodictyol) to flavan-4-ols (apiforol or luteoforol) in vitro . Our data indicate that the Sb06g029550 gene is involved in the 3-deoxyanthocyanidin synthesis pathway.

Description: Reproductive barriers are commonly observed in both animals and plants, in which they maintain species integrity and contribute to speciation. This report shows that a combination of loss-of-function alleles at two duplicated loci, DUPLICATED GAMETOPHYTIC STERILITY 1 ( DGS1 ) on chromosome 4 and DGS2 on chromosome 7, causes pollen sterility in hybrid progeny derived from an interspecific cross between cultivated rice, Oryza sativa , and an Asian annual wild rice, O. nivara . Male gametes carrying the DGS1 allele from O. nivara ( DGS1-nivara s ) and the DGS2 allele from O. sativa ( DGS2-T65 s ) were sterile, but female gametes carrying the same genotype were fertile. We isolated the causal gene, which encodes a protein homologous to DNA-dependent RNA polymerase (RNAP) III subunit C4 (RPC4). RPC4 facilitates the transcription of 5S rRNAs and tRNAs. The loss-of-function alleles at DGS1-nivara s and DGS2-T65 s were caused by weak or nonexpression of RPC4 and an absence of RPC4 , respectively. Phylogenetic analysis demonstrated that gene duplication of RPC4 at DGS1 and DGS2 was a recent event that occurred after divergence of the ancestral population of Oryza from other Poaceae or during diversification of AA-genome species.
