    Description / Table of Contents: Résumé L'étude de la multiplication initiale des effectifs de T. trifolii, élevés au laboratoire sur pousses de différents pieds de luzerne, a servi de test d'antibiose pour les cultures en plein champ. La distribution de l'antibiose, dans des échantillons importants de plantes appartenant à des cultivars sélectionnés pour leur résistance aux pucerons, a présenté une forme en J, c'est-à-dire que la majorité des plantes était très résistante, quelques unes apparemment sensibles, et un certain nombre intermédiaires entre ces deux extrêmes. Pour un niveau donné d'antibiose, la reproduction, la mortalité et ainsi la distribution initiale en âges dans les populations de pucerons ont été généralement identiques. La multiplication végétative de plantes présentant un gradient de résistance à l'intérieur d'un cultivar et l'utilisation d'un plan de distribution des boutures ont permis l'étude de ce qui semble être l'effet de l'hétérogénéité spatiale sur la résistance des cultures aux attaques de pucerons. La simulation d'une invasion de la culture par les pucerons en plaçant des adulte sur toutes les boutures d'un rang ne pouvait donner une explication de la croissance de la population que si les pucerons se déplacaient le long du rang pour découvrir et exploiter les pieds les plus sensibles. Une distribution par taches, comme on peut l'envisager dans un champ, ne devrait pas gêner les pucerons, car bien que les mouvements d'évasion soient stimulés par les niveaux de résistance élevés (de non-préférence), on peut en déduire que les pucerons se déplaceront sur des plantes très résistantes, eventuellement pour atteindre des plantes moins résistantes placées derriere.
    Notes: Abstract Initial population growth of spotted alfalfa aphid reared on shoots cut from individual lucerne plants, was tested and used as a realistic bioassay of antibiosis. Within cultivars selected for aphid-resistance there was a J-shaped distribution of antibiosis between plants of the crop, the majority being highly resistant, a few apparently susceptible and a proportion partly-resistant. For a given level of antibiosis, reproduction, mortality and thus initial age distribution of aphid populations were generally similar. Vegetative cloning of plants from the range of resistance available in a cultivar has allowed studies of the likely effect of spatial variation of resistance in crops on aphid infestations, using experimental arrays of cut shoots. Simulation of aphid invasion of crops by the placement of adults on all shoots of an array gave results explicable only if the aphids moved through the array to find and breed on the more susceptible plants. A patchy arrangement of these, as might be expected in a field crop, would not hinder the aphids, for although movement off a plant is stimulated by higher resistance (non-preference) levels, it was inferred that aphids will move onto higher resistance plants, eventually to reach lower resistance plants beyond.

    Temporary loss of antibiosis in plants of a lucerne cultivar selected for resistance to spotted alfalfa aphid (1988)

    Notes: Abstract In autumn 1981 there were widespread reports of a reduced level of antibiosis in lucerne crops and field trials where cultivars selected for resistance to the aphid, Therioaphis trifolii f. maculata, had been used. On our field trial, the plot of ‘CUF 101’ lucerne was infested to a level about 40% of that on the aphid-susceptible ‘Hunter River’, compared with an average of about 3% over the two years before and the two years after. An experimental study of possible causes using a bioassay technique on cloned plants representing the spectrum of resistance in CUF 101 indicated that loss of resistance was temporary and occurred apparently randomly among the tests, but that certain treatments increase the frequency of its occurrence. Lowered temperatures and the use of either young regrowth or senescent lucerne, each increased the frequency of loss of resistance. Inundation of lucerne by large numbers of aphids did not affect the expression of resistance directly, but the few progeny that survived to adulthood on partly-resistance lucerne were habituated and were then able to interact with the plants to increase the apparent frequency of breakdown of resistance. Plants which showed the loss of resistance developed aphid populations between 4x ad 25x those when they expressed their normal resistance level. Investigations suggest that the situation in autumn 1981 may have been the result of a prolonged and massive immigration of aphids into lucerne crops, which, on the aphid resistant cultivars allowed surviving aphids to exploit maximally the combined effects of factors causing some loss of resistance.

    Genetic selection of peptide inhibitors of biological pathways (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-07-27
    Description: Genetic selections were used to find peptides that inhibit biological pathways in budding yeast. The peptides were presented inside cells as peptamers, surface loops on a highly expressed and biologically inert carrier protein, a catalytically inactive derivative of staphylococcal nuclease. Peptamers that inhibited the pheromone signaling pathway, transcriptional silencing, and the spindle checkpoint were isolated. Putative targets for the inhibitors were identified by a combination of two-hybrid analysis and genetic dissection of the target pathways. This analysis identified Ydr517w as a component of the spindle checkpoint and reinforced earlier indications that Ste50 has both positive and negative roles in pheromone signaling. Analysis of transcript arrays showed that the peptamers were highly specific in their effects, which suggests that they may be useful reagents in organisms that lack sophisticated genetics as well as for identifying components of existing biological pathways that are potential targets for drug discovery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Norman, T C -- Smith, D L -- Sorger, P K -- Drees, B L -- O'Rourke, S M -- Hughes, T R -- Roberts, C J -- Friend, S H -- Fields, S -- Murray, A W -- P41-RR11823/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1999 Jul 23;285(5427):591-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, University of California, San Francisco, CA 94143-0444, USA. tnorman@microbia.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10417390" target="_blank"〉PubMed〈/a〉

    Persistent site-specific remodeling of a nucleosome array by transient action of the SWI/SNF complex (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-07-26
    Description: The SWI/SNF complex participates in the restructuring of chromatin for transcription. The function of the yeast SWI/SNF complex in the remodeling of a nucleosome array has now been analyzed in vitro. Binding of the purified SWI/SNF complex to a nucleosome array disrupted multiple nucleosomes in an adenosine triphosphate-dependent reaction. However, removal of SWI/SNF left a deoxyribonuclease I-hypersensitive site specifically at a nucleosome that was bound by derivatives of the transcription factor Gal4p. Analysis of individual nucleosomes revealed that the SWI/SNF complex catalyzed eviction of histones from the Gal4-bound nucleosomes. Thus, the transient action of the SWI/SNF complex facilitated irreversible disruption of transcription factor-bound nucleosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Owen-Hughes, T -- Utley, R T -- Cote, J -- Peterson, C L -- Workman, J L -- GM47867/GM/NIGMS NIH HHS/ -- R01 GM049650/GM/NIGMS NIH HHS/ -- R37 GM049650/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1996 Jul 26;273(5274):513-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology and Center for Gene Regulation, Pennsylvania State University, University Park, PA 16802-4500, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662543" target="_blank"〉PubMed〈/a〉

    The neuron-specific protein PGP 9.5 is a ubiquitin carboxyl-terminal hydrolase (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-03
    Description: A complementary DNA (cDNA) for ubiquitin carboxyl-terminal hydrolase isozyme L3 was cloned from human B cells. The cDNA encodes a protein of 230 amino acids with a molecular mass of 26.182 daltons. The human protein is very similar to the bovine homolog, with only three amino acids differing in over 100 residues compared. The amino acid sequence deduced from the cDNA was 54% identical to that of the neuron-specific protein PGP 9.5. Purification of bovine PGP 9.5 confirmed that it is also a ubiquitin carboxyl-terminal hydrolase. These results suggest that a family of such related proteins exists and that their expression is tissue-specific.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilkinson, K D -- Lee, K M -- Deshpande, S -- Duerksen-Hughes, P -- Boss, J M -- Pohl, J -- New York, N.Y. -- Science. 1989 Nov 3;246(4930):670-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Emory University School of Medicine, Atlanta, GA 30322.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2530630" target="_blank"〉PubMed〈/a〉

    A melanocortin 1 receptor allele suggests varying pigmentation among Neanderthals (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-27
    Description: The melanocortin 1 receptor (MC1R) regulates pigmentation in humans and other vertebrates. Variants of MC1R with reduced function are associated with pale skin color and red hair in humans of primarily European origin. We amplified and sequenced a fragment of the MC1R gene (mc1r) from two Neanderthal remains. Both specimens have a mutation that was not found in approximately 3700 modern humans analyzed. Functional analyses show that this variant reduces MC1R activity to a level that alters hair and/or skin pigmentation in humans. The impaired activity of this variant suggests that Neanderthals varied in pigmentation levels, potentially on the scale observed in modern humans. Our data suggest that inactive MC1R variants evolved independently in both modern humans and Neanderthals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lalueza-Fox, Carles -- Rompler, Holger -- Caramelli, David -- Staubert, Claudia -- Catalano, Giulio -- Hughes, David -- Rohland, Nadin -- Pilli, Elena -- Longo, Laura -- Condemi, Silvana -- de la Rasilla, Marco -- Fortea, Javier -- Rosas, Antonio -- Stoneking, Mark -- Schoneberg, Torsten -- Bertranpetit, Jaume -- Hofreiter, Michael -- New York, N.Y. -- Science. 2007 Nov 30;318(5855):1453-5.

    Diversity and complexity in DNA recognition by transcription factors (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-05-16
    Description: Sequence preferences of DNA binding proteins are a primary mechanism by which cells interpret the genome. Despite the central importance of these proteins in physiology, development, and evolution, comprehensive DNA binding specificities have been determined experimentally for only a few proteins. Here, we used microarrays containing all 10-base pair sequences to examine the binding specificities of 104 distinct mouse DNA binding proteins representing 22 structural classes. Our results reveal a complex landscape of binding, with virtually every protein analyzed possessing unique preferences. Roughly half of the proteins each recognized multiple distinctly different sequence motifs, challenging our molecular understanding of how proteins interact with their DNA binding sites. This complexity in DNA recognition may be important in gene regulation and in the evolution of transcriptional regulatory networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2905877/" 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/PMC2905877/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Badis, Gwenael -- Berger, Michael F -- Philippakis, Anthony A -- Talukder, Shaheynoor -- Gehrke, Andrew R -- Jaeger, Savina A -- Chan, Esther T -- Metzler, Genita -- Vedenko, Anastasia -- Chen, Xiaoyu -- Kuznetsov, Hanna -- Wang, Chi-Fong -- Coburn, David -- Newburger, Daniel E -- Morris, Quaid -- Hughes, Timothy R -- Bulyk, Martha L -- R01 HG003985/HG/NHGRI NIH HHS/ -- R01 HG003985-01/HG/NHGRI NIH HHS/ -- R01 HG003985-02/HG/NHGRI NIH HHS/ -- R01 HG003985-03/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1720-3. doi: 10.1126/science.1162327.

    Signatures of adaptation to obligate biotrophy in the Hyaloperonospora arabidopsidis genome (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-12-15
    Description: Many oomycete and fungal plant pathogens are obligate biotrophs, which extract nutrients only from living plant tissue and cannot grow apart from their hosts. Although these pathogens cause substantial crop losses, little is known about the molecular basis or evolution of obligate biotrophy. Here, we report the genome sequence of the oomycete Hyaloperonospora arabidopsidis (Hpa), an obligate biotroph and natural pathogen of Arabidopsis thaliana. In comparison with genomes of related, hemibiotrophic Phytophthora species, the Hpa genome exhibits dramatic reductions in genes encoding (i) RXLR effectors and other secreted pathogenicity proteins, (ii) enzymes for assimilation of inorganic nitrogen and sulfur, and (iii) proteins associated with zoospore formation and motility. These attributes comprise a genomic signature of evolution toward obligate biotrophy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3971456/" 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/PMC3971456/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baxter, Laura -- Tripathy, Sucheta -- Ishaque, Naveed -- Boot, Nico -- Cabral, Adriana -- Kemen, Eric -- Thines, Marco -- Ah-Fong, Audrey -- Anderson, Ryan -- Badejoko, Wole -- Bittner-Eddy, Peter -- Boore, Jeffrey L -- Chibucos, Marcus C -- Coates, Mary -- Dehal, Paramvir -- Delehaunty, Kim -- Dong, Suomeng -- Downton, Polly -- Dumas, Bernard -- Fabro, Georgina -- Fronick, Catrina -- Fuerstenberg, Susan I -- Fulton, Lucinda -- Gaulin, Elodie -- Govers, Francine -- Hughes, Linda -- Humphray, Sean -- Jiang, Rays H Y -- Judelson, Howard -- Kamoun, Sophien -- Kyung, Kim -- Meijer, Harold -- Minx, Patrick -- Morris, Paul -- Nelson, Joanne -- Phuntumart, Vipa -- Qutob, Dinah -- Rehmany, Anne -- Rougon-Cardoso, Alejandra -- Ryden, Peter -- Torto-Alalibo, Trudy -- Studholme, David -- Wang, Yuanchao -- Win, Joe -- Wood, Jo -- Clifton, Sandra W -- Rogers, Jane -- Van den Ackerveken, Guido -- Jones, Jonathan D G -- McDowell, John M -- Beynon, Jim -- Tyler, Brett M -- 079643/Wellcome Trust/United Kingdom -- BB/C509123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E007120/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E024815/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E024882/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F0161901/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G015244/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- EP/F500025/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- T12144/Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1549-51. doi: 10.1126/science.1195203.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Life Sciences, Warwick University, Wellesbourne, CV35 9EF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148394" target="_blank"〉PubMed〈/a〉

    Copy number variation of multiple genes at Rhg1 mediates nematode resistance in soybean (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-10-16
    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.

    Extensive diversity of Ig-superfamily proteins in the immune system of insects (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-08-20
    Description: The extensive somatic diversification of immune receptors is a hallmark of higher vertebrates. However, whether molecular diversity contributes to immune protection in invertebrates is unknown. We present evidence that Drosophila immune-competent cells have the potential to express more than 18,000 isoforms of the immunoglobulin (Ig)-superfamily receptor Down syndrome cell adhesion molecule (Dscam). Secreted protein isoforms of Dscam were detected in the hemolymph, and hemocyte-specific loss of Dscam impaired the efficiency of phagocytic uptake of bacteria, possibly due to reduced bacterial binding. Importantly, the molecular diversity of Dscam transcripts generated through a mechanism of alternative splicing is highly conserved across major insect orders, suggesting an unsuspected molecular complexity of the innate immune system of insects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, Fiona L -- Puttmann-Holgado, Roland -- Thomas, Franziska -- Lamar, David L -- Hughes, Michael -- Kondo, Masahiro -- Rebel, Vivienne I -- Schmucker, Dietmar -- 1RO1-NS46747-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 16;309(5742):1874-8.
