    Role of the guanosine triphosphatase Rac2 in T helper 1 cell differentiation (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-06-24
    Description: T helper 1 (TH1) cells mediate cellular immunity, whereas TH2 cells potentiate antiparasite and humoral immunity. We used a complementary DNA subtraction method, representational display analysis, to show that the small guanosine triphosphatase Rac2 is expressed selectively in murine TH1 cells. Rac induces the interferon-gamma (IFN-gamma) promoter through cooperative activation of the nuclear factor kappa B and p38 mitogen-activated protein kinase pathways. Tetracycline-regulated transgenic mice expressing constitutively active Rac2 in T cells exhibited enhanced IFN-gamma production. Dominant-negative Rac inhibited IFN-gamma production in murine T cells. Moreover, T cells from Rac2-/- mice showed decreased IFN-gamma production under TH1 conditions in vitro. Thus, Rac2 activates TH1-specific signaling and IFN-gamma gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, B -- Yu, H -- Zheng, W -- Voll, R -- Na, S -- Roberts, A W -- Williams, D A -- Davis, R J -- Ghosh, S -- Flavell, R A -- New York, N.Y. -- Science. 2000 Jun 23;288(5474):2219-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Immunobiology and Howard Hughes Medical Institute, Yale University School of Medicine, 310 Cedar Street, New Haven, CT 06520-8011, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10864872" target="_blank"〉PubMed〈/a〉

    Lower-crustal intrusion on the North Atlantic continental margin (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-03-28
    Description: When continents break apart, the rifting is sometimes accompanied by the production of large volumes of molten rock. The total melt volume, however, is uncertain, because only part of it has erupted at the surface. Furthermore, the cause of the magmatism is still disputed-specifically, whether or not it is due to increased mantle temperatures. We recorded deep-penetration normal-incidence and wide-angle seismic profiles across the Faroe and Hatton Bank volcanic margins in the northeast Atlantic. Here we show that near the Faroe Islands, for every 1 km along strike, 360-400 km(3) of basalt is extruded, while 540-600 km(3) is intruded into the continent-ocean transition. We find that lower-crustal intrusions are focused mainly into a narrow zone approximately 50 km wide on the transition, although extruded basalts flow more than 100 km from the rift. Seismic profiles show that the melt is intruded into the lower crust as sills, which cross-cut the continental fabric, rather than as an 'underplate' of 100 per cent melt, as has often been assumed. Evidence from the measured seismic velocities and from igneous thicknesses are consistent with the dominant control on melt production being increased mantle temperatures, with no requirement for either significant active small-scale mantle convection under the rift or the presence of fertile mantle at the time of continental break-up, as has previously been suggested for the North Atlantic Ocean.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, R S -- Smith, L K -- Roberts, A W -- Christie, P A F -- Kusznir, N J -- iSIMM Team -- Roberts, A M -- Healy, D -- Spitzer, R -- Chappell, A -- Eccles, J D -- Fletcher, R -- Hurst, N -- Lunnon, Z -- Parkin, C J -- Tymms, V J -- England -- Nature. 2008 Mar 27;452(7186):460-4. doi: 10.1038/nature06687.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bullard Laboratories, University of Cambridge, Madingley Road, Cambridge CB3 0EZ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18368115" target="_blank"〉PubMed〈/a〉

    The Selaginella genome identifies genetic changes associated with the evolution of vascular plants (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-05-10
    Description: Vascular plants appeared ~410 million years ago, then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported. By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Selaginella differs in posttranscriptional gene regulation, including small RNA regulation of repetitive elements, an absence of the trans-acting small interfering RNA pathway, and extensive RNA editing of organellar genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3166216/" 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/PMC3166216/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banks, Jo Ann -- Nishiyama, Tomoaki -- Hasebe, Mitsuyasu -- Bowman, John L -- Gribskov, Michael -- dePamphilis, Claude -- Albert, Victor A -- Aono, Naoki -- Aoyama, Tsuyoshi -- Ambrose, Barbara A -- Ashton, Neil W -- Axtell, Michael J -- Barker, Elizabeth -- Barker, Michael S -- Bennetzen, Jeffrey L -- Bonawitz, Nicholas D -- Chapple, Clint -- Cheng, Chaoyang -- Correa, Luiz Gustavo Guedes -- Dacre, Michael -- DeBarry, Jeremy -- Dreyer, Ingo -- Elias, Marek -- Engstrom, Eric M -- Estelle, Mark -- Feng, Liang -- Finet, Cedric -- Floyd, Sandra K -- Frommer, Wolf B -- Fujita, Tomomichi -- Gramzow, Lydia -- Gutensohn, Michael -- Harholt, Jesper -- Hattori, Mitsuru -- Heyl, Alexander -- Hirai, Tadayoshi -- Hiwatashi, Yuji -- Ishikawa, Masaki -- Iwata, Mineko -- Karol, Kenneth G -- Koehler, Barbara -- Kolukisaoglu, Uener -- Kubo, Minoru -- Kurata, Tetsuya -- Lalonde, Sylvie -- Li, Kejie -- Li, Ying -- Litt, Amy -- Lyons, Eric -- Manning, Gerard -- Maruyama, Takeshi -- Michael, Todd P -- Mikami, Koji -- Miyazaki, Saori -- Morinaga, Shin-ichi -- Murata, Takashi -- Mueller-Roeber, Bernd -- Nelson, David R -- Obara, Mari -- Oguri, Yasuko -- Olmstead, Richard G -- Onodera, Naoko -- Petersen, Bent Larsen -- Pils, Birgit -- Prigge, Michael -- Rensing, Stefan A -- Riano-Pachon, Diego Mauricio -- Roberts, Alison W -- Sato, Yoshikatsu -- Scheller, Henrik Vibe -- Schulz, Burkhard -- Schulz, Christian -- Shakirov, Eugene V -- Shibagaki, Nakako -- Shinohara, Naoki -- Shippen, Dorothy E -- Sorensen, Iben -- Sotooka, Ryo -- Sugimoto, Nagisa -- Sugita, Mamoru -- Sumikawa, Naomi -- Tanurdzic, Milos -- Theissen, Gunter -- Ulvskov, Peter -- Wakazuki, Sachiko -- Weng, Jing-Ke -- Willats, William W G T -- Wipf, Daniel -- Wolf, Paul G -- Yang, Lixing -- Zimmer, Andreas D -- Zhu, Qihui -- Mitros, Therese -- Hellsten, Uffe -- Loque, Dominique -- Otillar, Robert -- Salamov, Asaf -- Schmutz, Jeremy -- Shapiro, Harris -- Lindquist, Erika -- Lucas, Susan -- Rokhsar, Daniel -- Grigoriev, Igor V -- GM065383/GM/NIGMS NIH HHS/ -- GM84051/GM/NIGMS NIH HHS/ -- HG004164/HG/NHGRI NIH HHS/ -- R01 GM043644/GM/NIGMS NIH HHS/ -- R01 GM084051/GM/NIGMS NIH HHS/ -- R01 GM084051-01A1/GM/NIGMS NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-02/HG/NHGRI NIH HHS/ -- R01 HG004164-03/HG/NHGRI NIH HHS/ -- R01 HG004164-04/HG/NHGRI NIH HHS/ -- T32 GM007757/GM/NIGMS NIH HHS/ -- T32-HG00035/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2011 May 20;332(6032):960-3. doi: 10.1126/science.1203810.

    Repeated polyploidization of Gossypium genomes and the evolution of spinnable cotton fibres (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-12-22
    Description: Polyploidy often confers emergent properties, such as the higher fibre productivity and quality of tetraploid cottons than diploid cottons bred for the same environments. Here we show that an abrupt five- to sixfold ploidy increase approximately 60 million years (Myr) ago, and allopolyploidy reuniting divergent Gossypium genomes approximately 1-2 Myr ago, conferred about 30-36-fold duplication of ancestral angiosperm (flowering plant) genes in elite cottons (Gossypium hirsutum and Gossypium barbadense), genetic complexity equalled only by Brassica among sequenced angiosperms. Nascent fibre evolution, before allopolyploidy, is elucidated by comparison of spinnable-fibred Gossypium herbaceum A and non-spinnable Gossypium longicalyx F genomes to one another and the outgroup D genome of non-spinnable Gossypium raimondii. The sequence of a G. hirsutum A(t)D(t) (in which 't' indicates tetraploid) cultivar reveals many non-reciprocal DNA exchanges between subgenomes that may have contributed to phenotypic innovation and/or other emergent properties such as ecological adaptation by polyploids. Most DNA-level novelty in G. hirsutum recombines alleles from the D-genome progenitor native to its New World habitat and the Old World A-genome progenitor in which spinnable fibre evolved. Coordinated expression changes in proximal groups of functionally distinct genes, including a nuclear mitochondrial DNA block, may account for clusters of cotton-fibre quantitative trait loci affecting diverse traits. Opportunities abound for dissecting emergent properties of other polyploids, particularly angiosperms, by comparison to diploid progenitors and outgroups.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paterson, Andrew H -- Wendel, Jonathan F -- Gundlach, Heidrun -- Guo, Hui -- Jenkins, Jerry -- Jin, Dianchuan -- Llewellyn, Danny -- Showmaker, Kurtis C -- Shu, Shengqiang -- Udall, Joshua -- Yoo, Mi-jeong -- Byers, Robert -- Chen, Wei -- Doron-Faigenboim, Adi -- Duke, Mary V -- Gong, Lei -- Grimwood, Jane -- Grover, Corrinne -- Grupp, Kara -- Hu, Guanjing -- Lee, Tae-ho -- Li, Jingping -- Lin, Lifeng -- Liu, Tao -- Marler, Barry S -- Page, Justin T -- Roberts, Alison W -- Romanel, Elisson -- Sanders, William S -- Szadkowski, Emmanuel -- Tan, Xu -- Tang, Haibao -- Xu, Chunming -- Wang, Jinpeng -- Wang, Zining -- Zhang, Dong -- Zhang, Lan -- Ashrafi, Hamid -- Bedon, Frank -- Bowers, John E -- Brubaker, Curt L -- Chee, Peng W -- Das, Sayan -- Gingle, Alan R -- Haigler, Candace H -- Harker, David -- Hoffmann, Lucia V -- Hovav, Ran -- Jones, Donald C -- Lemke, Cornelia -- Mansoor, Shahid -- ur Rahman, Mehboob -- Rainville, Lisa N -- Rambani, Aditi -- Reddy, Umesh K -- Rong, Jun-kang -- Saranga, Yehoshua -- Scheffler, Brian E -- Scheffler, Jodi A -- Stelly, David M -- Triplett, Barbara A -- Van Deynze, Allen -- Vaslin, Maite F S -- Waghmare, Vijay N -- Walford, Sally A -- Wright, Robert J -- Zaki, Essam A -- Zhang, Tianzhen -- Dennis, Elizabeth S -- Mayer, Klaus F X -- Peterson, Daniel G -- Rokhsar, Daniel S -- Wang, Xiyin -- Schmutz, Jeremy -- England -- Nature. 2012 Dec 20;492(7429):423-7. doi: 10.1038/nature11798.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Genome Mapping Laboratory, University of Georgia, Athens, Georgia 30602, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23257886" target="_blank"〉PubMed〈/a〉

    Cellulose microfibril structure: inspirations from plant diversity (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-03-24
    Description: Cellulose microfibrils are synthesized at the plasma membrane by cellulose synthase catalytic subunits that associate to form cellulose synthesis complexes. Variation in the organization of these complexes underlies the variation in cellulose microfibril structure among diverse organisms. However, little is known about how the catalytic subunits interact to form complexes with different morphologies. We are using an evolutionary approach to investigate the roles of different catalytic subunit isoforms in organisms that have rosette-type cellulose synthesis complexes.

    Verification of velocity-resistivity relationships derived from structural joint inversion with borehole data (2013)
    Wiley
    Details
    Publication Date: 2013-06-27
    Description: [1]  We present results of three-dimensional joint inversion of seismic, magnetotelluric and gravity data over a marine salt dome. Such structures are difficult to image with a single method and our results demonstrate how combining different techniques can yield improved results. More importantly, we examine the reliability of velocity-conductivity relationships derived from structure-coupled joint inversion approaches. Comparison with a seismic reflection section shows that our models match the upper limit of the salt. Furthermore, velocity and resistivity logs from a borehole drilled into the salt dome's flank match, within error, those recovered by the inversion. The good match suggests that the difference in length scale does not have a significant effect in this case. This provides a strong incentive to incorporate borehole data into the joint inversion in the future and substantiates approaches that use the relationships derived from joint inversion models for lithological classification.

    Determination of natural responses of mechanical systems using correlation techniques (1975)

    Notes: Abstract The natural responses of linear systems may be found by observation of the system's response to a known stimulus. In such tests, the observations required ore the response as a function of time when the stimulus is deterministic in form. In practical situations, the application of this method is often hampered by the presence in the response of extraneous noise and the necessity of using large-amplitude excitations. The difficulties of the method outlined may be avoided by using random stimuli and cross correlations to obtain a statistical estimate of the natural modes. This paper describes one application in which the critical speeds and relative deflection amplitudes of a machine shaft-rotor system were found with the system either stationary or running at some arbitrary speed.
