    Description: The rhg1-b allele of soybean is widely used for resistance against soybean cyst nematode (SCN), the most economically damaging pathogen of soybeans in the United States. Gene silencing showed that genes in a 31-kilobase segment at rhg1-b, encoding an amino acid transporter, an alpha-SNAP protein, and a WI12 (wound-inducible domain) protein, each contribute to resistance. There is one copy of the 31-kilobase segment per haploid genome in susceptible varieties, but 10 tandem copies are present in an rhg1-b haplotype. Overexpression of the individual genes in roots was ineffective, but overexpression of the genes together conferred enhanced SCN resistance. Hence, SCN resistance mediated by the soybean quantitative trait locus Rhg1 is conferred by copy number variation that increases the expression of a set of dissimilar genes in a repeated multigene segment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cook, David E -- Lee, Tong Geon -- Guo, Xiaoli -- Melito, Sara -- Wang, Kai -- Bayless, Adam M -- Wang, Jianping -- Hughes, Teresa J -- Willis, David K -- Clemente, Thomas E -- Diers, Brian W -- Jiang, Jiming -- Hudson, Matthew E -- Bent, Andrew F -- New York, N.Y. -- Science. 2012 Nov 30;338(6111):1206-9. doi: 10.1126/science.1228746.

    Description: Gut microbial communities represent one source of human genetic and metabolic diversity. To examine how gut microbiomes differ among human populations, here we characterize bacterial species in fecal samples from 531 individuals, plus the gene content of 110 of them. The cohort encompassed healthy children and adults from the Amazonas of Venezuela, rural Malawi and US metropolitan areas and included mono- and dizygotic twins. Shared features of the functional maturation of the gut microbiome were identified during the first three years of life in all three populations, including age-associated changes in the genes involved in vitamin biosynthesis and metabolism. Pronounced differences in bacterial assemblages and functional gene repertoires were noted between US residents and those in the other two countries. These distinctive features are evident in early infancy as well as adulthood. Our findings underscore the need to consider the microbiome when evaluating human development, nutritional needs, physiological variations and the impact of westernization.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3376388/" 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/PMC3376388/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yatsunenko, Tanya -- Rey, Federico E -- Manary, Mark J -- Trehan, Indi -- Dominguez-Bello, Maria Gloria -- Contreras, Monica -- Magris, Magda -- Hidalgo, Glida -- Baldassano, Robert N -- Anokhin, Andrey P -- Heath, Andrew C -- Warner, Barbara -- Reeder, Jens -- Kuczynski, Justin -- Caporaso, J Gregory -- Lozupone, Catherine A -- Lauber, Christian -- Clemente, Jose Carlos -- Knights, Dan -- Knight, Rob -- Gordon, Jeffrey I -- DK078669/DK/NIDDK NIH HHS/ -- K01 DK090285/DK/NIDDK NIH HHS/ -- K05 AA017688/AA/NIAAA NIH HHS/ -- P01 DK078669/DK/NIDDK NIH HHS/ -- P01 DK078669-05/DK/NIDDK NIH HHS/ -- T32 HD049338-06/HD/NICHD NIH HHS/ -- T32-HD049338/HD/NICHD NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 May 9;486(7402):222-7. doi: 10.1038/nature11053.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genome Sciences and Systems Biology, Washington University School of Medicine, St Louis, Missouri 63108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22699611" target="_blank"〉PubMed〈/a〉

    Description: Author(s): Giuseppe Clemente and Massimo D’Elia We propose a new method to characterize the different phases observed in the nonperturbative numerical approach to quantum gravity known as causal dynamical triangulations. The method is based on the analysis of the eigenvalues and the eigenvectors of the Laplace-Beltrami operator computed on the tr... [Phys. Rev. D 97, 124022] Published Tue Jun 12, 2018

    Description: A low-error 16S ribosomal RNA amplicon sequencing method, in combination with whole-genome sequencing of 〉500 cultured isolates, was used to characterize bacterial strain composition in the fecal microbiota of 37 U.S. adults sampled for up to 5 years. Microbiota stability followed a power-law function, which when extrapolated suggests that most strains in an individual are residents for decades. Shared strains were recovered from family members but not from unrelated individuals. Sampling of individuals who consumed a monotonous liquid diet for up to 32 weeks indicated that changes in strain composition were better predicted by changes in weight than by differences in sampling interval. This combination of stability and responsiveness to physiologic change confirms the potential of the gut microbiota as a diagnostic tool and therapeutic target.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3791589/" 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/PMC3791589/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faith, Jeremiah J -- Guruge, Janaki L -- Charbonneau, Mark -- Subramanian, Sathish -- Seedorf, Henning -- Goodman, Andrew L -- Clemente, Jose C -- Knight, Rob -- Heath, Andrew C -- Leibel, Rudolph L -- Rosenbaum, Michael -- Gordon, Jeffrey I -- DK078669/DK/NIDDK NIH HHS/ -- DK30292/DK/NIDDK NIH HHS/ -- DK64774/DK/NIDDK NIH HHS/ -- DK70977/DK/NIDDK NIH HHS/ -- K05 AA017688/AA/NIAAA NIH HHS/ -- P01 DK078669/DK/NIDDK NIH HHS/ -- P30 DK026687/DK/NIDDK NIH HHS/ -- P60 DK020541/DK/NIDDK NIH HHS/ -- R01 DK064773/DK/NIDDK NIH HHS/ -- R01 DK070977/DK/NIDDK NIH HHS/ -- R37 DK030292/DK/NIDDK NIH HHS/ -- UL1TR000040/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Jul 5;341(6141):1237439. doi: 10.1126/science.1237439.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genome Sciences and Systems Biology, Washington University School of Medicine, St. Louis, MO 63108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23828941" target="_blank"〉PubMed〈/a〉
