    Description: Minor histocompatibility (H) antigens can be peptides derived from cellular proteins that are presented on the cell surface by major histocompatibility complex (MHC) class I molecules. This is similar to viral antigens, because in both cases cytotoxic T lymphocytes (CTLs) recognize artificially produced peptides loaded on target cells. Naturally processed minor H peptides were found to be similar to those artificial CTL-epitopes, as far as size and hydrophobicity is concerned. The peptides studied were isolated from a transfectant that expressed a model CTL-defined antigen, beta-galactosidase, from male cells that express H-Y, which has been known operationally since 1955, and from cells that express H-4, known since 1961.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rotzschke, O -- Falk, K -- Wallny, H J -- Faath, S -- Rammensee, H G -- New York, N.Y. -- Science. 1990 Jul 20;249(4966):283-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Biologie, Abteilung Immungenetik, Tubingen, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1695760" target="_blank"〉PubMed〈/a〉

    Description: Malignant hyperthermia (MH) causes neurological, liver, and kidney damage and death in humans and major economic losses in the swine industry. A single point mutation in the porcine gene for the skeletal muscle ryanodine receptor (ryr1) was found to be correlated with MH in five major breeds of lean, heavily muscled swine. Haplotyping suggests that the mutation in all five breeds has a common origin. Assuming that this is the causal mutation for MH, the development of a noninvasive diagnostic test will provide the basis for elimination of the MH gene or its controlled inclusion in swine breeding programs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fujii, J -- Otsu, K -- Zorzato, F -- de Leon, S -- Khanna, V K -- Weiler, J E -- O'Brien, P J -- MacLennan, D H -- New York, N.Y. -- Science. 1991 Jul 26;253(5018):448-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Banting and Best Department of Medical Research, University of Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1862346" target="_blank"〉PubMed〈/a〉

    Description: The traditional view that Old World fruit bats (Megachiroptera) and insect bats (Microchiroptera) are closely related has been challenged by claims that Megachiroptera are the sister group to flying lemurs (Dermoptera) or Primates. We found that the specialized muscles of the rostral part of the wing in Microchiroptera and Megachiroptera receive double innervation by both the facial nerve and cervical spinal nerves, suggesting that bats are monophyletic. Innervation by the facial nerve also occurs in Dermoptera and suggests that bats and Dermoptera share a common ancestor that had wings.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thewissen, J G -- Babcock, S K -- New York, N.Y. -- Science. 1991 Feb 22;251(4996):934-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Anthropology and Anatomy, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2000493" target="_blank"〉PubMed〈/a〉

    Description: Competition between larval populations of the native North American treehole mosquito Aedes triseriatus and Aedes albopictus, recently introduced from Asia to North America, was assessed by comparing per capita growth rate estimates for experimental cohorts of larvae developing under a variety of initial density combinations in fluid obtained from tires or from treeholes. Estimates of carrying capacities and competition coefficients indicate that competition between the two species will result in stable coexistence in treehole communities but local extinction of A. triseriatus in tire habitats.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Livdahl, T P -- Willey, M S -- R15AI27940/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 12;253(5016):189-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Clark University, Worcester, MA 01610.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1853204" target="_blank"〉PubMed〈/a〉

    Description: The dinitroaniline herbicide trifluralin (alpha, alpha, alpha-trifluoro-2,6-dinitro-N, N-dipropyl-p-toluidine), at micromolar concentrations, selectively inhibited both proliferation and differentiation of the parasitic protozoan Leishmania mexicana amazonensis. In vitro, radioactive trifluralin showed specific binding to leishmania tubulin but not to mammalian tubulin. Because herbicides such as trifluralin are economical and are considered safe for man and domesticated animals, they may serve as useful sources of potential antiparasitic agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, M M -- Fong, D -- AI 21364/AI/NIAID NIH HHS/ -- CA 49359/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1990 Aug 24;249(4971):924-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Rutgers, State University of New Jersey, Piscataway 08855.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2392684" target="_blank"〉PubMed〈/a〉

    Description: Female birds that do not normally sing possess brain nuclei associated with song production in males. To determine whether one song nucleus, the caudal nucleus of the ventral hyperstriatum (HVc), acts in conspecific song perception, courtship responses of female canaries to canary and white-crowned sparrow songs were compared before and after HVc lesions. Bilateral lesions of a portion of the HVc resulted in copulation solicitations to heterospecific song as well as conspecific song. Control females continued to respond only to conspecific song. This suggests that the HVc is critical for conspecific song perception in females. Because female canaries do not normally sing, neurons in female HVc must develop response selectivity by a mechanism different from that proposed for male birds in the motor theory of song perception.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brenowitz, E A -- DC 00487/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 1991 Jan 18;251(4991):303-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Washington, Seattle 98195.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1987645" target="_blank"〉PubMed〈/a〉

    Description: Variations in the absorption spectra of cone photopigments over the spectral range of about 530 to 562 nanometers are a principal cause of individual differences in human color vision and of differences in color vision within and across other primates. To study the molecular basis of these variations, nucleotide sequences were determined for eight primate photopigment genes. The spectral peaks of the pigments specified by these genes spanned the range from 530 to 562 nanometers. Comparisons of the deduced amino acid sequences of these eight pigments suggest that three amino acid substitutions produce the approximately 30-nanometer difference in spectral peaks of the pigments underlying human red-green color vision, and red shifts of specific magnitudes are produced by replacement of nonpolar with hydroxyl-bearing amino acids at each of the three critical positions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Neitz, M -- Neitz, J -- Jacobs, G H -- EY-02052/EY/NEI NIH HHS/ -- EY-07200/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 17;252(5008):971-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of California, Santa Barbara 93106.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1903559" target="_blank"〉PubMed〈/a〉

    Description: Conus venoms contain a remarkable diversity of pharmacologically active small peptides. Their targets are ion channels and receptors in the neuromuscular system. The venom of Conus geographus contains high-affinity peptides that act on voltage-sensitive calcium channels, sodium channels, N-methyl-D-aspartate (NMDA) receptors, acetylcholine receptors, and vasopressin receptors; many more peptides with still uncharacterized receptor targets are present in this venom. It now seems that the Conus species (approximately 500 in number) will each use a distinctive assortment of peptides and that the pharmacological diversity in Conus venoms may be ultimately comparable to that of plant alkaloids or secondary metabolites of microorganisms. The cone snails may generate this diverse spectrum of venom peptides by a "fold-lock-cut" synthetic pathway. These peptides are specific enough to discriminate effectively between closely related receptor subtypes and can be used for structure-function correlations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olivera, B M -- Rivier, J -- Clark, C -- Ramilo, C A -- Corpuz, G P -- Abogadie, F C -- Mena, E E -- Woodward, S R -- Hillyard, D R -- Cruz, L J -- GM 22737/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Jul 20;249(4966):257-63.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Utah, Salt Lake City 84112.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2165278" target="_blank"〉PubMed〈/a〉

    Description: Human immunodeficiency virus (HIV) frequently causes neurological dysfunction and is abundantly expressed in the central nervous system (CNS) of acquired immunodeficiency syndrome (AIDS) patients with HIV encephalitis or myelopathy. The virus is found mostly in cells of the monocyte-macrophage lineage within the CNS, but the possibility of infection of other glial cells has been raised. Therefore, the effects of different HIV-1 and HIV-2 strains were studied in primary cultures of adult human brain containing microglial cells, the resident CNS macrophages, and astrocytes. These cultures could be productively infected with macrophage-adapted HIV-1 isolates but not with T lymphocyte-adapted HIV-1 isolates or two HIV-2 isolates. As determined with a triple-label procedure, primary astrocytes did not express HIV gag antigens and remained normal throughout the 3-week course of infection. In contrast, virus replicated in neighboring microglial cells, often leading to their cell fusion and death. The death of microglial cells, which normally serve immune functions in the CNS, may be a key factor in the pathogenesis of AIDS encephalitis or myelopathy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watkins, B A -- Dorn, H H -- Kelly, W B -- Armstrong, R C -- Potts, B J -- Michaels, F -- Kufta, C V -- Dubois-Dalcq, M -- New York, N.Y. -- Science. 1990 Aug 3;249(4968):549-53.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Viral and Molecular Pathogenesis, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2200125" target="_blank"〉PubMed〈/a〉

These song cycles, which are altered by mutations in the clock gene period, exhibit a species-specific variation that facilitates mating. We have used chimeric period gene constructs from Drosophila melanogaster and Drosophila simulans in germline transformation experiments to map the genetic control of their song rhythm difference to a small segment of the amino acid encoding information within this gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wheeler, D A -- Kyriacou, C P -- Greenacre, M L -- Yu, Q -- Rutila, J E -- Rosbash, M -- Hall, J C -- GM-21473/GM/NIGMS NIH HHS/ -- GM-33205/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Mar 1;251(4997):1082-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Brandeis University, Waltham, MA 02254.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1900131" target="_blank"〉PubMed〈/a〉

    Description: In order to identify genes specific for the sensory neurons of Aplysia, a miniaturized differential screening method based on the polymerase chain reaction and applicable to small amounts of tissue was used. One messenger RNA was isolated that is expressed in every mechanoreceptor sensory cluster of the Aplysia central nervous system. This messenger RNA encodes a peptide that seems to function as an inhibitory cotransmitter. The peptide selectively inhibits certain postsynaptic cells but not others and thereby allows the sensory neurons to achieve target-specific synaptic actions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brunet, J F -- Shapiro, E -- Foster, S A -- Kandel, E R -- Iino, Y -- New York, N.Y. -- Science. 1991 May 10;252(5007):856-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, New York, NY.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1840700" target="_blank"〉PubMed〈/a〉

    Description: Attine ants engage in a quadripartite symbiosis with fungi they cultivate for food, specialized garden parasites, and parasite-inhibiting bacteria. Molecular phylogenetic evidence supports an ancient host-pathogen association between the ant-cultivar mutualism and the garden parasite. Here we show that ants rear the antibiotic-producing bacteria in elaborate cuticular crypts, supported by unique exocrine glands, and that these structures have been highly modified across the ants' evolutionary history. This specialized structural evolution, together with the absence of these bacteria and modifications in other ant genera that do not grow fungus, indicate that the bacteria have an ancient and coevolved association with the ants, their fungal cultivar, and the garden parasite.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Currie, Cameron R -- Poulsen, Michael -- Mendenhall, John -- Boomsma, Jacobus J -- Billen, Johan -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):81-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bacteriology, University of Wisconsin at Madison, Madison, WI 53706, USA. currie@bact.wisc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400148" target="_blank"〉PubMed〈/a〉

    Description: In flowering plants, signaling between the male pollen tube and the synergid cells of the female gametophyte is required for fertilization. In the Arabidopsis thaliana mutant feronia (fer), fertilization is impaired; the pollen tube fails to arrest and thus continues to grow inside the female gametophyte. FER encodes a synergid-expressed, plasma membrane-localized receptor-like kinase. We found that the FER protein accumulates asymmetrically in the synergid membrane at the filiform apparatus. Interspecific crosses using pollen from Arabidopsis lyrata and Cardamine flexuosa on A. thaliana stigmas resulted in a fer-like phenotype that correlates with sequence divergence in the extracellular domain of FER. Our findings show that the female control of pollen tube reception is based on a FER-dependent signaling pathway, which may play a role in reproductive isolation barriers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Escobar-Restrepo, Juan-Miguel -- Huck, Norbert -- Kessler, Sharon -- Gagliardini, Valeria -- Gheyselinck, Jacqueline -- Yang, Wei-Cai -- Grossniklaus, Ueli -- New York, N.Y. -- Science. 2007 Aug 3;317(5838):656-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Plant Biology and Zurich-Basel Plant Science Center, University of Zurich, Zollikerstrasse 107, CH-8008 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17673660" target="_blank"〉PubMed〈/a〉

    Description: Morphological variation within species is a raw material subject to natural selection. However, temporal change in morphological diversity has usually been studied in terms of variation among rather than within species. The distribution of polymorphic traits in cladistic character-taxon matrices reveals that the frequency and extent of morphological variation in 982 trilobite species are greatest early in the evolution of the group: Stratigraphically old and/or phylogenetically basal taxa are significantly more variable than younger and/or more derived taxa. Through its influence on evolutionary tempo, high intraspecific variation may have played a major role in the pronounced Cambrian diversification of trilobites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Webster, Mark -- New York, N.Y. -- Science. 2007 Jul 27;317(5837):499-502.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of the Geophysical Sciences, University of Chicago, 5734 South Ellis Avenue, Chicago, IL 60637, USA. mwebster@geosci.uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17656721" target="_blank"〉PubMed〈/a〉

    Description: Humans are capable of making inferences about other individuals' intentions and goals by evaluating their actions in relation to the constraints imposed by the environment. This capacity enables humans to go beyond the surface appearance of behavior to draw inferences about an individual's mental states. Presently unclear is whether this capacity is uniquely human or is shared with other animals. We show that cotton-top tamarins, rhesus macaques, and chimpanzees all make spontaneous inferences about a human experimenter's goal by attending to the environmental constraints that guide rational action. These findings rule out simple associative accounts of action perception and show that our capacity to infer rational, goal-directed action likely arose at least as far back as the New World monkeys, some 40 million years ago.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wood, Justin N -- Glynn, David D -- Phillips, Brenda C -- Hauser, Marc D -- CM-5-P40RR003640-13/CM/NCI NIH HHS/ -- F31MH075298/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 7;317(5843):1402-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Harvard University, Cambridge, MA 02138, USA. jwood@wjh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17823353" target="_blank"〉PubMed〈/a〉

    Description: The forces that maintain genetic diversity among individuals and diversity among species are usually studied separately. Nevertheless, diversity at one of these levels may depend on the diversity at the other. We have combined observations of natural populations, quantitative genetics, and field experiments to show that genetic variation in the concentration of an allelopathic secondary compound in Brassica nigra is necessary for the coexistence of B. nigra and its competitor species. In addition, the diversity of competing species was required for the maintenance of genetic variation in the trait within B. nigra. Thus, conservation of species diversity may also necessitate maintenance of the processes that sustain the genetic diversity of each individual species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lankau, Richard A -- Strauss, Sharon Y -- New York, N.Y. -- Science. 2007 Sep 14;317(5844):1561-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Evolution and Ecology, University of California- Davis, One Shields Avenue, Davis, CA 95616, USA. ralankau@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17872447" target="_blank"〉PubMed〈/a〉

    Description: Prions are lethal mammalian pathogens composed of aggregated conformational isomers of a host-encoded glycoprotein and which appear to lack nucleic acids. Their unique biology, allied with the public-health risks posed by prion zoonoses such as bovine spongiform encephalopathy, has focused much attention on the molecular basis of prion propagation and the "species barrier" that controls cross-species transmission. Both are intimately linked to understanding how multiple prion "strains" are encoded by a protein-only agent. The underlying mechanisms are clearly of much wider importance, and analogous protein-based inheritance mechanisms are recognized in yeast and fungi. Recent advances suggest that prions themselves are not directly neurotoxic, but rather their propagation involves production of toxic species, which may be uncoupled from infectivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Collinge, John -- Clarke, Anthony R -- MC_U123160656/Medical Research Council/United Kingdom -- MC_U123192748/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 Nov 9;318(5852):930-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MRC Prion Unit, Department of Neurodegenerative Disease, UCL Institute of Neurology, London WC1N 3BG, UK. j.collinge@prion.ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17991853" target="_blank"〉PubMed〈/a〉

    Description: The rhesus macaque (Macaca mulatta) is an abundant primate species that diverged from the ancestors of Homo sapiens about 25 million years ago. Because they are genetically and physiologically similar to humans, rhesus monkeys are the most widely used nonhuman primate in basic and applied biomedical research. We determined the genome sequence of an Indian-origin Macaca mulatta female and compared the data with chimpanzees and humans to reveal the structure of ancestral primate genomes and to identify evidence for positive selection and lineage-specific expansions and contractions of gene families. A comparison of sequences from individual animals was used to investigate their underlying genetic diversity. The complete description of the macaque genome blueprint enhances the utility of this animal model for biomedical research and improves our understanding of the basic biology of the species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rhesus Macaque Genome Sequencing and Analysis Consortium -- Gibbs, Richard A -- Rogers, Jeffrey -- Katze, Michael G -- Bumgarner, Roger -- Weinstock, George M -- Mardis, Elaine R -- Remington, Karin A -- Strausberg, Robert L -- Venter, J Craig -- Wilson, Richard K -- Batzer, Mark A -- Bustamante, Carlos D -- Eichler, Evan E -- Hahn, Matthew W -- Hardison, Ross C -- Makova, Kateryna D -- Miller, Webb -- Milosavljevic, Aleksandar -- Palermo, Robert E -- Siepel, Adam -- Sikela, James M -- Attaway, Tony -- Bell, Stephanie -- Bernard, Kelly E -- Buhay, Christian J -- Chandrabose, Mimi N -- Dao, Marvin -- Davis, Clay -- Delehaunty, Kimberly D -- Ding, Yan -- Dinh, Huyen H -- Dugan-Rocha, Shannon -- Fulton, Lucinda A -- Gabisi, Ramatu Ayiesha -- Garner, Toni T -- Godfrey, Jennifer -- Hawes, Alicia C -- Hernandez, Judith -- Hines, Sandra -- Holder, Michael -- Hume, Jennifer -- Jhangiani, Shalini N -- Joshi, Vandita -- Khan, Ziad Mohid -- Kirkness, Ewen F -- Cree, Andrew -- Fowler, R Gerald -- Lee, Sandra -- Lewis, Lora R -- Li, Zhangwan -- Liu, Yih-Shin -- Moore, Stephanie M -- Muzny, Donna -- Nazareth, Lynne V -- Ngo, Dinh Ngoc -- Okwuonu, Geoffrey O -- Pai, Grace -- Parker, David -- Paul, Heidie A -- Pfannkoch, Cynthia -- Pohl, Craig S -- Rogers, Yu-Hui -- Ruiz, San Juana -- Sabo, Aniko -- Santibanez, Jireh -- Schneider, Brian W -- Smith, Scott M -- Sodergren, Erica -- Svatek, Amanda F -- Utterback, Teresa R -- Vattathil, Selina -- Warren, Wesley -- White, Courtney Sherell -- Chinwalla, Asif T -- Feng, Yucheng -- Halpern, Aaron L -- Hillier, Ladeana W -- Huang, Xiaoqiu -- Minx, Pat -- Nelson, Joanne O -- Pepin, Kymberlie H -- Qin, Xiang -- Sutton, Granger G -- Venter, Eli -- Walenz, Brian P -- Wallis, John W -- Worley, Kim C -- Yang, Shiaw-Pyng -- Jones, Steven M -- Marra, Marco A -- Rocchi, Mariano -- Schein, Jacqueline E -- Baertsch, Robert -- Clarke, Laura -- Csuros, Miklos -- Glasscock, Jarret -- Harris, R Alan -- Havlak, Paul -- Jackson, Andrew R -- Jiang, Huaiyang -- Liu, Yue -- Messina, David N -- Shen, Yufeng -- Song, Henry Xing-Zhi -- Wylie, Todd -- Zhang, Lan -- Birney, Ewan -- Han, Kyudong -- Konkel, Miriam K -- Lee, Jungnam -- Smit, Arian F A -- Ullmer, Brygg -- Wang, Hui -- Xing, Jinchuan -- Burhans, Richard -- Cheng, Ze -- Karro, John E -- Ma, Jian -- Raney, Brian -- She, Xinwei -- Cox, Michael J -- Demuth, Jeffery P -- Dumas, Laura J -- Han, Sang-Gook -- Hopkins, Janet -- Karimpour-Fard, Anis -- Kim, Young H -- Pollack, Jonathan R -- Vinar, Tomas -- Addo-Quaye, Charles -- Degenhardt, Jeremiah -- Denby, Alexandra -- Hubisz, Melissa J -- Indap, Amit -- Kosiol, Carolin -- Lahn, Bruce T -- Lawson, Heather A -- Marklein, Alison -- Nielsen, Rasmus -- Vallender, Eric J -- Clark, Andrew G -- Ferguson, Betsy -- Hernandez, Ryan D -- Hirani, Kashif -- Kehrer-Sawatzki, Hildegard -- Kolb, Jessica -- Patil, Shobha -- Pu, Ling-Ling -- Ren, Yanru -- Smith, David Glenn -- Wheeler, David A -- Schenck, Ian -- Ball, Edward V -- Chen, Rui -- Cooper, David N -- Giardine, Belinda -- Hsu, Fan -- Kent, W James -- Lesk, Arthur -- Nelson, David L -- O'brien, William E -- Prufer, Kay -- Stenson, Peter D -- Wallace, James C -- Ke, Hui -- Liu, Xiao-Ming -- Wang, Peng -- Xiang, Andy Peng -- Yang, Fan -- Barber, Galt P -- Haussler, David -- Karolchik, Donna -- Kern, Andy D -- Kuhn, Robert M -- Smith, Kayla E -- Zwieg, Ann S -- 062023/Wellcome Trust/United Kingdom -- R01 HG002939/HG/NHGRI NIH HHS/ -- U54 HG003068/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):222-34.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genome Sequencing Center, Baylor College of Medicine, Houston, TX 77030, USA. agibbs@bcm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431167" target="_blank"〉PubMed〈/a〉

    Description: Because bacterial recombination involves the occasional transfer of small DNA fragments between strains, different sets of niche-specific genes may be maintained in populations that freely recombine at other loci. Therefore, genetic isolation may be established at different times for different chromosomal regions during speciation as recombination at niche-specific genes is curtailed. To test this model, we separated sequence divergence into rate and time components, revealing that different regions of the Escherichia coli and Salmonella enterica chromosomes diverged over a approximately 70-million-year period. Genetic isolation first occurred at regions carrying species-specific genes, indicating that physiological distinctiveness between the nascent Escherichia and Salmonella lineages was maintained for tens of millions of years before the complete genetic isolation of their chromosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Retchless, Adam C -- Lawrence, Jeffrey G -- GM078092/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Aug 24;317(5841):1093-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Pittsburgh, Pittsburgh, PA 15260, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17717188" target="_blank"〉PubMed〈/a〉

    Description: Knowledge of the rhesus macaque genome sequence enables reconstruction of the ancestral state of the human genome before the divergence of chimpanzees. However, the draft quality of nonhuman primate genome assemblies challenges the ability of current methods to detect insertions, deletions, and copy-number variations between humans, chimpanzees, and rhesus macaques and hinders the identification of evolutionary changes between these species. Because of the abundance of segmental duplications, genome comparisons require the integration of genomic assemblies and data from large-insert clones, linkage maps, and radiation hybrid maps. With genomic triangulation, an integrative method that reconstructs ancestral states and the structural evolution of genomes, we identified 130 human-specific breakpoints in genome structure due to rearrangements at an intermediate scale (10 kilobases to 4 megabases), including 64 insertions affecting 58 genes. Comparison with a human structural polymorphism database indicates that many of the rearrangements are polymorphic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harris, R A -- Rogers, J -- Milosavljevic, A -- R01 004009-1/PHS HHS/ -- R01 02583-01/PHS HHS/ -- R24-RR015383/RR/NCRR NIH HHS/ -- U01 RR 18464/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):235-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Human Genetics, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431168" target="_blank"〉PubMed〈/a〉

    Description: Humans have many cognitive skills not possessed by their nearest primate relatives. The cultural intelligence hypothesis argues that this is mainly due to a species-specific set of social-cognitive skills, emerging early in ontogeny, for participating and exchanging knowledge in cultural groups. We tested this hypothesis by giving a comprehensive battery of cognitive tests to large numbers of two of humans' closest primate relatives, chimpanzees and orangutans, as well as to 2.5-year-old human children before literacy and schooling. Supporting the cultural intelligence hypothesis and contradicting the hypothesis that humans simply have more "general intelligence," we found that the children and chimpanzees had very similar cognitive skills for dealing with the physical world but that the children had more sophisticated cognitive skills than either of the ape species for dealing with the social world.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herrmann, Esther -- Call, Josep -- Hernandez-Lloreda, Maraa Victoria -- Hare, Brian -- Tomasello, Michael -- New York, N.Y. -- Science. 2007 Sep 7;317(5843):1360-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Evolutionary Anthropology, Leipzig, D-04103, Germany. eherrman@eva.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17823346" target="_blank"〉PubMed〈/a〉

    Description: The bacterium Proteus mirabilis is capable of movement on solid surfaces by a type of motility called swarming. Boundaries form between swarming colonies of different P. mirabilis strains but not between colonies of a single strain. A fundamental requirement for boundary formation is the ability to discriminate between self and nonself. We have isolated mutants that form boundaries with their parent.

    Description: Carbon dioxide (CO2) elicits different olfactory behaviors across species. In Drosophila, neurons that detect CO2 are located in the antenna, form connections in a ventral glomerulus in the antennal lobe, and mediate avoidance. By contrast, in the mosquito these neurons are in the maxillary palps (MPs), connect to medial sites, and promote attraction. We found in Drosophila that loss of a microRNA, miR-279, leads to formation of CO2 neurons in the MPs. miR-279 acts through down-regulation of the transcription factor Nerfin-1. The ectopic neurons are hybrid cells. They express CO2 receptors and form connections characteristic of CO2 neurons, while exhibiting wiring and receptor characteristics of MP olfactory receptor neurons (ORNs). We propose that this hybrid ORN reveals a cellular intermediate in the evolution of species-specific behaviors elicited by CO2.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2714168/" 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/PMC2714168/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cayirlioglu, Pelin -- Kadow, Ilona Grunwald -- Zhan, Xiaoli -- Okamura, Katsutomo -- Suh, Greg S B -- Gunning, Dorian -- Lai, Eric C -- Zipursky, S Lawrence -- DC006485/DC/NIDCD NIH HHS/ -- R01 GM083300/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1256-60. doi: 10.1126/science.1149483.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, Howard Hughes Medical Institute, David Geffen School of Medicine, University of California, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18309086" target="_blank"〉PubMed〈/a〉

    Description: Studies suggest that populations of different species do not decline equally after habitat loss. However, empirical tests have been confined to fine spatiotemporal scales and have rarely included plants. Using data from 89,365 forest survey plots covering peninsular Spain, we explored, for each of 34 common tree species, the relationship between probability of occurrence and the local cover of remaining forest. Twenty-four species showed a significant negative response to forest loss, so that decreased forest cover had a negative effect on tree diversity, but the responses of individual species were highly variable. Animal-dispersed species were less vulnerable to forest loss, with six showing positive responses to decreased forest cover. The results imply that plant-animal interactions help prevent the collapse of forest communities that suffer habitat destruction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Montoya, Daniel -- Zavala, Miguel A -- Rodriguez, Miguel A -- Purves, Drew W -- New York, N.Y. -- Science. 2008 Jun 13;320(5882):1502-4. doi: 10.1126/science.1158404.

    Description: The spike protein (S) of SARS coronavirus (SARS-CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction. The crystal structure at 2.9 angstrom resolution of the RBD bound with the peptidase domain of human ACE2 shows that the RBD presents a gently concave surface, which cradles the N-terminal lobe of the peptidase. The atomic details at the interface between the two proteins clarify the importance of residue changes that facilitate efficient cross-species infection and human-to-human transmission. The structure of the RBD suggests ways to make truncated disulfide-stabilized RBD variants for use in the design of coronavirus vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Fang -- Li, Wenhui -- Farzan, Michael -- Harrison, Stephen C -- AI061601/AI/NIAID NIH HHS/ -- CA13202/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 16;309(5742):1864-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry and Molecular Pharmacology, Harvard Medical School and Laboratory of Molecular Medicine, 320 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16166518" target="_blank"〉PubMed〈/a〉

    Description: Obligate Acacia ant plants house mutualistic ants as a defense mechanism and provide them with extrafloral nectar (EFN). Ant/plant mutualisms are widespread, but little is known about the biochemical basis of their species specificity. Despite its importance in these and other plant/animal interactions, little attention has been paid to the control of the chemical composition of nectar. We found high invertase (sucrose-cleaving) activity in Acacia EFN, which thus contained no sucrose. Sucrose, a disaccharide common in other EFNs, usually attracts nonsymbiotic ants. The EFN of the ant acacias was therefore unattractive to such ants. The Pseudomyrmex ants that are specialized to live on Acacia had almost no invertase activity in their digestive tracts and preferred sucrose-free EFN. Our results demonstrate postsecretory regulation of the carbohydrate composition of nectar.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heil, M -- Rattke, J -- Boland, W -- New York, N.Y. -- Science. 2005 Apr 22;308(5721):560-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioorganic Chemistry, Max-Planck-Institute for Chemical Ecology, Hans-Knoll-Strasse 8, D-07745 Jena, Germany.

    Description: Infection of mice with an attenuated Creutzfeldt-Jakob disease agent (SY-CJD) interferes with superinfection by a more virulent human-derived CJD agent (FU-CJD) and does not require pathological prion protein (PrPres). Using a rapid coculture system, we found that a neural cell line free of immune system cells similarly supported substantial CJD agent interference without PrPres. In addition, SY-CJD prevented superinfection by sheep-derived Chandler (Ch) and 22L scrapie agents. However, only 22L and not Ch prevented FU-CJD infection, even though both scrapie strains provoked abundant PrPres. This relationship between particular strains of sheep- and human-derived agents is likely to affect their prevalence and epidemic spread.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nishida, Noriuki -- Katamine, Shigeru -- Manuelidis, Laura -- NS12674/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2005 Oct 21;310(5747):493-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Yale Medical School, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16239476" target="_blank"〉PubMed〈/a〉

    Description: Theileria annulata and T. parva are closely related protozoan parasites that cause lymphoproliferative diseases of cattle. We sequenced the genome of T. annulata and compared it with that of T. parva to understand the mechanisms underlying transformation and tropism. Despite high conservation of gene sequences and synteny, the analysis reveals unequally expanded gene families and species-specific genes. We also identify divergent families of putative secreted polypeptides that may reduce immune recognition, candidate regulators of host-cell transformation, and a Theileria-specific protein domain [frequently associated in Theileria (FAINT)] present in a large number of secreted proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pain, Arnab -- Renauld, Hubert -- Berriman, Matthew -- Murphy, Lee -- Yeats, Corin A -- Weir, William -- Kerhornou, Arnaud -- Aslett, Martin -- Bishop, Richard -- Bouchier, Christiane -- Cochet, Madeleine -- Coulson, Richard M R -- Cronin, Ann -- de Villiers, Etienne P -- Fraser, Audrey -- Fosker, Nigel -- Gardner, Malcolm -- Goble, Arlette -- Griffiths-Jones, Sam -- Harris, David E -- Katzer, Frank -- Larke, Natasha -- Lord, Angela -- Maser, Pascal -- McKellar, Sue -- Mooney, Paul -- Morton, Fraser -- Nene, Vishvanath -- O'Neil, Susan -- Price, Claire -- Quail, Michael A -- Rabbinowitsch, Ester -- Rawlings, Neil D -- Rutter, Simon -- Saunders, David -- Seeger, Kathy -- Shah, Trushar -- Squares, Robert -- Squares, Steven -- Tivey, Adrian -- Walker, Alan R -- Woodward, John -- Dobbelaere, Dirk A E -- Langsley, Gordon -- Rajandream, Marie-Adele -- McKeever, Declan -- Shiels, Brian -- Tait, Andrew -- Barrell, Bart -- Hall, Neil -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 1;309(5731):131-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SA, UK. ap2@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15994557" target="_blank"〉PubMed〈/a〉

    Description: Plants, like animals, use signal transduction pathways based on heterotrimeric guanine nucleotide-binding proteins (G proteins) to regulate many aspects of development and cell signaling. Some components of G protein signaling are highly conserved between plants and animals and some are not.

    Description: Life-history theory attempts to provide evolutionary explanations for variations in the ways in which animal species live their lives. Recent analyses have suggested that the dimensionless ratios of several key life-history parameters are the same for different species, even across distant taxa. However, we show here that previous analyses may have given a false picture and created an illusion of invariants, which do not necessarily exist; essentially, this is because life-history variables have been regressed against themselves. The following question arises from our analysis: How do we identify an invariant?〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nee, Sean -- Colegrave, Nick -- West, Stuart A -- Grafen, Alan -- New York, N.Y. -- Science. 2005 Aug 19;309(5738):1236-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Evolutionary Biology, School of Biological Sciences, University of Edinburgh, West Mains Road, Edinburgh, EH9 3JT, UK. sean.nee@ed.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16109879" target="_blank"〉PubMed〈/a〉

    Description: The determination of the chimpanzee genome sequence provides a means to study both structural and functional aspects of the evolution of the human genome. Here we compare humans and chimpanzees with respect to differences in expression levels and protein-coding sequences for genes active in brain, heart, liver, kidney, and testis. We find that the patterns of differences in gene expression and gene sequences are markedly similar. In particular, there is a gradation of selective constraints among the tissues so that the brain shows the least differences between the species whereas liver shows the most. Furthermore, expression levels as well as amino acid sequences of genes active in more tissues have diverged less between the species than have genes active in fewer tissues. In general, these patterns are consistent with a model of neutral evolution with negative selection. However, for X-chromosomal genes expressed in testis, patterns suggestive of positive selection on sequence changes as well as expression changes are seen. Furthermore, although genes expressed in the brain have changed less than have genes expressed in other tissues, in agreement with previous work we find that genes active in brain have accumulated more changes on the human than on the chimpanzee lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Khaitovich, Philipp -- Hellmann, Ines -- Enard, Wolfgang -- Nowick, Katja -- Leinweber, Marcus -- Franz, Henriette -- Weiss, Gunter -- Lachmann, Michael -- Paabo, Svante -- New York, N.Y. -- Science. 2005 Sep 16;309(5742):1850-4.

    Description: Thousands of mammalian messenger RNAs are under selective pressure to maintain 7-nucleotide sites matching microRNAs (miRNAs). We found that these conserved targets are often highly expressed at developmental stages before miRNA expression and that their levels tend to fall as the miRNA that targets them begins to accumulate. Nonconserved sites, which outnumber the conserved sites 10 to 1, also mediate repression. As a consequence, genes preferentially expressed at the same time and place as a miRNA have evolved to selectively avoid sites matching the miRNA. This phenomenon of selective avoidance extends to thousands of genes and enables spatial and temporal specificities of miRNAs to be revealed by finding tissues and developmental stages in which messages with corresponding sites are expressed at lower levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Farh, Kyle Kai-How -- Grimson, Andrew -- Jan, Calvin -- Lewis, Benjamin P -- Johnston, Wendy K -- Lim, Lee P -- Burge, Christopher B -- Bartel, David P -- New York, N.Y. -- Science. 2005 Dec 16;310(5755):1817-21.

    Description: A major suspected bias in the fossil record of skeletonized groups is variation in preservability owing to differences in shell composition. However, despite extensive changes in shell composition over the 500-million-year history of marine bivalves, genus duration and shell composition show few significant relationships, and of those, virtually all are contrary to bias from preferential loss of highly reactive shell types. Distortion of large-scale temporal patterns in marine bivalves owing to preservability is thus apparently weak or randomly distributed, which increases the likelihood that observed patterns in this and other shelled groups carry a strong biological signal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kidwell, Susan M -- New York, N.Y. -- Science. 2005 Feb 11;307(5711):914-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geophysical Sciences, University of Chicago, 5734 South Ellis Avenue, Chicago, IL 60637, USA. skidwell@uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15705849" target="_blank"〉PubMed〈/a〉

    Description: We have reconstructed the events that led to the evolution of a key physiological innovation underpinning the large adaptive radiation of fishes, namely their unique ability to secrete molecular oxygen (O2). We show that O2 secretion into the swimbladder evolved some 100 million years after another O2-secreting system in the eye. We unravel the likely sequence in which the functional components of both systems evolved. These components include ocular and swimbladder countercurrent exchangers, the Bohr and Root effects, the buffering power and surface histidine content of hemoglobins, and red blood cell Na+/H+ exchange activity. Our synthesis reveals the dynamics of gains and losses of these multiple traits over time, accounting for part of the huge diversity of form and function in living fishes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berenbrink, Michael -- Koldkjaer, Pia -- Kepp, Oliver -- Cossins, Andrew R -- New York, N.Y. -- Science. 2005 Mar 18;307(5716):1752-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, University of Liverpool, Crown Street, Liverpool L69 7ZB, UK. michaelb@liv.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15774753" target="_blank"〉PubMed〈/a〉

    Description: Previous genome comparisons have suggested that one important trend in vertebrate evolution has been a sharp rise in intron abundance. By using genomic data and expressed sequence tags from the marine annelid Platynereis dumerilii, we provide direct evidence that about two-thirds of human introns predate the bilaterian radiation but were lost from insect and nematode genomes to a large extent. A comparison of coding exon sequences confirms the ancestral nature of Platynereis and human genes. Thus, the urbilaterian ancestor had complex, intron-rich genes that have been retained in Platynereis and human.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raible, Florian -- Tessmar-Raible, Kristin -- Osoegawa, Kazutoyo -- Wincker, Patrick -- Jubin, Claire -- Balavoine, Guillaume -- Ferrier, David -- Benes, Vladimir -- de Jong, Pieter -- Weissenbach, Jean -- Bork, Peer -- Arendt, Detlev -- BBS/B/12067/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2005 Nov 25;310(5752):1325-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Developmental Unit, European Molecular Biological Laboratory (EMBL), Meyerhofstrasse 1, D-69117 Heidelberg, Germany. raible@embl.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16311335" target="_blank"〉PubMed〈/a〉

    Description: A comparison of gene content and genome architecture of Trypanosoma brucei, Trypanosoma cruzi, and Leishmania major, three related pathogens with different life cycles and disease pathology, revealed a conserved core proteome of about 6200 genes in large syntenic polycistronic gene clusters. Many species-specific genes, especially large surface antigen families, occur at nonsyntenic chromosome-internal and subtelomeric regions. Retroelements, structural RNAs, and gene family expansion are often associated with syntenic discontinuities that-along with gene divergence, acquisition and loss, and rearrangement within the syntenic regions-have shaped the genomes of each parasite. Contrary to recent reports, our analyses reveal no evidence that these species are descended from an ancestor that contained a photosynthetic endosymbiont.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉El-Sayed, Najib M -- Myler, Peter J -- Blandin, Gaelle -- Berriman, Matthew -- Crabtree, Jonathan -- Aggarwal, Gautam -- Caler, Elisabet -- Renauld, Hubert -- Worthey, Elizabeth A -- Hertz-Fowler, Christiane -- Ghedin, Elodie -- Peacock, Christopher -- Bartholomeu, Daniella C -- Haas, Brian J -- Tran, Anh-Nhi -- Wortman, Jennifer R -- Alsmark, U Cecilia M -- Angiuoli, Samuel -- Anupama, Atashi -- Badger, Jonathan -- Bringaud, Frederic -- Cadag, Eithon -- Carlton, Jane M -- Cerqueira, Gustavo C -- Creasy, Todd -- Delcher, Arthur L -- Djikeng, Appolinaire -- Embley, T Martin -- Hauser, Christopher -- Ivens, Alasdair C -- Kummerfeld, Sarah K -- Pereira-Leal, Jose B -- Nilsson, Daniel -- Peterson, Jeremy -- Salzberg, Steven L -- Shallom, Joshua -- Silva, Joana C -- Sundaram, Jaideep -- Westenberger, Scott -- White, Owen -- Melville, Sara E -- Donelson, John E -- Andersson, Bjorn -- Stuart, Kenneth D -- Hall, Neil -- AI045039/AI/NIAID NIH HHS/ -- AI45038/AI/NIAID NIH HHS/ -- AI45061/AI/NIAID NIH HHS/ -- R01 AI043062/AI/NIAID NIH HHS/ -- U01 AI040599/AI/NIAID NIH HHS/ -- U01 AI043062/AI/NIAID NIH HHS/ -- U01 AI045038/AI/NIAID NIH HHS/ -- U01 AI045039/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 15;309(5733):404-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, 9712 Medical Center Drive, Rockville, MD 20850, USA. nelsayed@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16020724" target="_blank"〉PubMed〈/a〉

    Description: Molecular and antigenic analyses of three influenza viruses isolated from outbreaks of severe respiratory disease in racing greyhounds revealed that they are closely related to H3N8 equine influenza virus. Phylogenetic analysis indicated that the canine influenza virus genomes form a monophyletic group, consistent with a single interspecies virus transfer. Molecular changes in the hemagglutinin suggested adaptive evolution in the new host. The etiologic role of this virus in respiratory disease was supported by the temporal association of rising antibody titers with disease and by experimental inoculation studies. The geographic expansion of the infection and its persistence for several years indicate efficient transmission of canine influenza virus among greyhounds. Evidence of infection in pet dogs suggests that this infection may also become enzootic in this population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crawford, P C -- Dubovi, Edward J -- Castleman, William L -- Stephenson, Iain -- Gibbs, E P J -- Chen, Limei -- Smith, Catherine -- Hill, Richard C -- Ferro, Pamela -- Pompey, Justine -- Bright, Rick A -- Medina, Marie-Jo -- Johnson, Calvin M -- Olsen, Christopher W -- Cox, Nancy J -- Klimov, Alexander I -- Katz, Jacqueline M -- Donis, Ruben O -- New York, N.Y. -- Science. 2005 Oct 21;310(5747):482-5.

    Description: With the use of synthetic biology, we reduced the Escherichia coli K-12 genome by making planned, precise deletions. The multiple-deletion series (MDS) strains, with genome reductions up to 15%, were designed by identifying nonessential genes and sequences for elimination, including recombinogenic or mobile DNA and cryptic virulence genes, while preserving good growth profiles and protein production. Genome reduction also led to unanticipated beneficial properties: high electroporation efficiency and accurate propagation of recombinant genes and plasmids that were unstable in other strains.

    Description: Most emerging infectious diseases in humans originate from animal reservoirs; to contain and eradicate these diseases we need to understand how and why some pathogens become capable of crossing host species barriers. Influenza virus illustrates the interaction of factors that limit the transmission and subsequent establishment of an infection in a novel host species. Influenza species barriers can be categorized into virus-host interactions occurring within individuals and host-host interactions, either within or between species, that affect transmission between individuals. Viral evolution can help surmount species barriers, principally by affecting virus-host interactions; however, evolving the capability for sustained transmission in a new host species represents a major adaptive challenge because the number of mutations required is often large.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuiken, Thijs -- Holmes, Edward C -- McCauley, John -- Rimmelzwaan, Guus F -- Williams, Catherine S -- Grenfell, Bryan T -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):394-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Virology, Erasmus Medical Center, 3015 GE Rotterdam, Netherlands. t.kuiken@erasmusmc.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16627737" target="_blank"〉PubMed〈/a〉

    Description: An 852-base pair region of the cytochrome-b gene was sequenced for the brood parasitic cowbirds and 20 additional taxa of the New World blackbirds (Icterinae). The goal of the study was to determine (i) whether interspecific brood parasitism is multiply derived within the assemblage and (ii) the nature of the evolutionary transformation between various forms of interspecific brood parasitism. Cladistic analysis of the sequence data indicates that brood parasitism evolved a single time within the Icterinae. The primitive form of interspecific brood parasitism in this assemblage is host-specificity, with host-generality representing the derived condition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lanyon, S M -- New York, N.Y. -- Science. 1992 Jan 3;255(5040):77-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, Field Museum of Natural History, Chicago, IL 60605-2496.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1553533" target="_blank"〉PubMed〈/a〉

    Description: In Caenorhabditis, the vulva is formed in the central body region from three of six equivalent cells and is induced by the gonad. In some nematodes, however, the vulva is located in the posterior body region. Vulval development has been analyzed in three such genera. The same precursor cells give rise to the vulva in Caenorhabditis and in the posterior vulva species, but in the latter the cells first migrate posteriorly. In two such species, the vulva is not induced by the gonad, but instead relies on intrinsic properties of precursor cells. Thus, evolution of organ position involves changes in induction and competence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sommer, R J -- Sternberg, P W -- New York, N.Y. -- Science. 1994 Jul 1;265(5168):114-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8016644" target="_blank"〉PubMed〈/a〉

    Description: Although sexual isolation is one of the most important causes of speciation, its genetic basis is largely unknown. Here evidence is presented that suggests that sexual isolation between two closely related species of Drosophila is largely caused by differences in female cuticular hydrocarbons. This difference maps to only one of the three major chromosomes, implying that reproductive isolation might have a fairly simple genetic basis. The effect of the hydrocarbons on courtship may help explain the ubiquitous asymmetry of sexual isolation between many pairs of Drosophila species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coyne, J A -- Crittenden, A P -- Mah, K -- GM 38462/GM/NIGMS NIH HHS/ -- GM 50355/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 2;265(5177):1461-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8073292" target="_blank"〉PubMed〈/a〉

    Description: The origin of new genes includes both the initial molecular events and subsequent population dynamics. A processed Drosophila alcohol dehydrogenase (Adh) gene, previously thought to be a pseudogene, provided an opportunity to examine the two phases of the origin of a new gene. The sequence of the processed Adh messenger RNA became part of a new functional gene by capturing several upstream exons and introns of an unrelated gene. This novel chimeric gene, jingwei, differs from its parent Adh gene in both its pattern of expression and rate of molecular evolution. Natural selection participated in the origin and subsequent evolution of this gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Long, M -- Langley, C H -- New York, N.Y. -- Science. 1993 Apr 2;260(5104):91-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Genetics, University of California, Davis 95616.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7682012" target="_blank"〉PubMed〈/a〉

    Description: An RNA polymerase II transcription system was resolved and reconstituted from extracts of Schizosaccharomyces pombe. Exchange with components of a Saccharomyces cerevisiae system was undertaken to reveal the factor or factors responsible for the difference in location of the transcription start site, about 30 base pairs and 40 to 120 base pairs downstream of the TATA box in S. pombe and S. cerevisiae, respectively. Two components, counterparts of human transcription factor IIF (TFIIF) and TFIIH, could be exchanged individually between systems without effect on the start site. Three components, counterparts of human TFIIB, TFIIE, and RNA polymerase II, could not be exchanged individually but could be swapped in the pairs TFIIE-TFIIH and TFIIB-RNA polymerase II, which demonstrates that there are functional interactions between these components. Moreover, exchange of the latter pair shifted the starting position, which shows that TFIIB and RNA polymerase II are solely responsible for determining the start site of transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Y -- Flanagan, P M -- Tschochner, H -- Kornberg, R D -- GM36659/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Feb 11;263(5148):805-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Stanford University, School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303296" target="_blank"〉PubMed〈/a〉

    Description: The glycosylphosphatidylinositol (GPI) anchor is a membrane attachment structure of many proteins and occurs in a wide variety of eukaryotes from yeasts to mammals. The structure of the core of the GPI anchor is conserved in protozoa and mammals and so is its biosynthetic pathway. A complementary DNA encoding a human protein termed PIG-A (phosphatidylinositol glycan-class A) was cloned. PIG-A was necessary for synthesis of N-acetylglucosaminyl-phosphatidylinositol, the very early intermediate in GPI-anchor biosynthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miyata, T -- Takeda, J -- Iida, Y -- Yamada, N -- Inoue, N -- Takahashi, M -- Maeda, K -- Kitani, T -- Kinoshita, T -- New York, N.Y. -- Science. 1993 Feb 26;259(5099):1318-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunoregulation, Osaka University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7680492" target="_blank"〉PubMed〈/a〉

    Description: The hemagglutinin (HA) structure at 2.9 angstrom resolution, from a highly pathogenic Vietnamese H5N1 influenza virus, is more related to the 1918 and other human H1 HAs than to a 1997 duck H5 HA. Glycan microarray analysis of this Viet04 HA reveals an avian alpha2-3 sialic acid receptor binding preference. Introduction of mutations that can convert H1 serotype HAs to human alpha2-6 receptor specificity only enhanced or reduced affinity for avian-type receptors. However, mutations that can convert avian H2 and H3 HAs to human receptor specificity, when inserted onto the Viet04 H5 HA framework, permitted binding to a natural human alpha2-6 glycan, which suggests a path for this H5N1 virus to gain a foothold in the human population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, James -- Blixt, Ola -- Tumpey, Terrence M -- Taubenberger, Jeffery K -- Paulson, James C -- Wilson, Ian A -- AI058113/AI/NIAID NIH HHS/ -- AI42266/AI/NIAID NIH HHS/ -- CA55896/CA/NCI NIH HHS/ -- GM060938/GM/NIGMS NIH HHS/ -- GM062116/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):404-10.

    Description: Gamete recognition proteins can evolve at astonishing rates and lie at the heart of reproductive isolation and speciation in diverse taxa. However, the source of selection driving this evolution remains unknown. We report on how the sperm bindin genotype influences reproductive success under natural conditions. An interaction between genotype frequency and spawning density determines how sperm bindin genotype influences reproductive success. Common genotypes are selected under sperm-limited conditions, whereas rare genotypes are selected under conditions of intense sperm competition and sexual conflict. Variation in the evolutionary rates of bindin may reflect historic differences in sperm availability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levitan, Don R -- Ferrell, David L -- New York, N.Y. -- Science. 2006 Apr 14;312(5771):267-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Science, Florida State University, Tallahassee, Florida 32306-1100, USA. levitan@bio.fsu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16614223" target="_blank"〉PubMed〈/a〉

    Description: Highly pathogenic avian influenza virus (H5N1) may cause severe lower respiratory tract (LRT) disease in humans. However, the LRT cells to which the virus attaches are unknown for both humans and other mammals. We show here that H5N1 virus attached predominantly to type II pneumocytes, alveolar macrophages, and nonciliated bronchiolar cells in the human LRT, and this pattern was most closely mirrored in cat and ferret tissues. These findings may explain, at least in part, the localization and severity of H5N1 viral pneumonia in humans. They also identify the cat and the ferret as suitable experimental animals based on this criterion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Riel, Debby -- Munster, Vincent J -- de Wit, Emmie -- Rimmelzwaan, Guus F -- Fouchier, Ron A M -- Osterhaus, Ab D M E -- Kuiken, Thijs -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):399.

    Description: Mosquitoes are vectors of parasitic and viral diseases of immense importance for public health. The acquisition of the genome sequence of the yellow fever and Dengue vector, Aedes aegypti (Aa), has enabled a comparative phylogenomic analysis of the insect immune repertoire: in Aa, the malaria vector Anopheles gambiae (Ag), and the fruit fly Drosophila melanogaster (Dm). Analysis of immune signaling pathways and response modules reveals both conservative and rapidly evolving features associated with different functional gene categories and particular aspects of immune reactions. These dynamics reflect in part continuous readjustment between accommodation and rejection of pathogens and suggest how innate immunity may have evolved.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2042107/" 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/PMC2042107/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Waterhouse, Robert M -- Kriventseva, Evgenia V -- Meister, Stephan -- Xi, Zhiyong -- Alvarez, Kanwal S -- Bartholomay, Lyric C -- Barillas-Mury, Carolina -- Bian, Guowu -- Blandin, Stephanie -- Christensen, Bruce M -- Dong, Yuemei -- Jiang, Haobo -- Kanost, Michael R -- Koutsos, Anastasios C -- Levashina, Elena A -- Li, Jianyong -- Ligoxygakis, Petros -- Maccallum, Robert M -- Mayhew, George F -- Mendes, Antonio -- Michel, Kristin -- Osta, Mike A -- Paskewitz, Susan -- Shin, Sang Woon -- Vlachou, Dina -- Wang, Lihui -- Wei, Weiqi -- Zheng, Liangbiao -- Zou, Zhen -- Severson, David W -- Raikhel, Alexander S -- Kafatos, Fotis C -- Dimopoulos, George -- Zdobnov, Evgeny M -- Christophides, George K -- 1 R01 AI059492-01A1/AI/NIAID NIH HHS/ -- 5 R01 AI61576-2/AI/NIAID NIH HHS/ -- G0300170/Medical Research Council/United Kingdom -- GM41247/GM/NIGMS NIH HHS/ -- GR077229MA/Wellcome Trust/United Kingdom -- P01 AI044220-06A1/AI/NIAID NIH HHS/ -- R01 AI037083/AI/NIAID NIH HHS/ -- R01 GM058634/GM/NIGMS NIH HHS/ -- R01 GM058634-09/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Jun 22;316(5832):1738-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cell and Molecular Biology, Faculty of Natural Sciences, Imperial College London, London SW7 2AZ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17588928" target="_blank"〉PubMed〈/a〉

    Description: Mating with another species (hybridization) is often maladaptive. Consequently, females typically avoid heterospecifics as mates. Contrary to these expectations, female spadefoot toads were more likely to choose heterospecific males when exposed to environmental conditions that favor hybridization. Indeed, those females with phenotypic characteristics for which hybridization is most favorable were most likely to switch from choosing conspecifics to heterospecifics. Moreover, environmentally dependent mate choice has evolved only in populations and species that risk engaging in, and can potentially benefit from, hybridization. Thus, when the benefits of mate choice vary, females may radically alter their mate selection in response to their own phenotype and their environment, even to the point of choosing males of other species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfennig, Karin S -- New York, N.Y. -- Science. 2007 Nov 9;318(5852):965-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Campus Box 3280, Coker Hall, University of North Carolina, Chapel Hill, NC 27599, USA. kpfennig@email.unc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17991861" target="_blank"〉PubMed〈/a〉

    Description: We present a draft sequence of the genome of Aedes aegypti, the primary vector for yellow fever and dengue fever, which at approximately 1376 million base pairs is about 5 times the size of the genome of the malaria vector Anopheles gambiae. Nearly 50% of the Ae. aegypti genome consists of transposable elements. These contribute to a factor of approximately 4 to 6 increase in average gene length and in sizes of intergenic regions relative to An. gambiae and Drosophila melanogaster. Nonetheless, chromosomal synteny is generally maintained among all three insects, although conservation of orthologous gene order is higher (by a factor of approximately 2) between the mosquito species than between either of them and the fruit fly. An increase in genes encoding odorant binding, cytochrome P450, and cuticle domains relative to An. gambiae suggests that members of these protein families underpin some of the biological differences between the two mosquito species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2868357/" 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/PMC2868357/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nene, Vishvanath -- Wortman, Jennifer R -- Lawson, Daniel -- Haas, Brian -- Kodira, Chinnappa -- Tu, Zhijian Jake -- Loftus, Brendan -- Xi, Zhiyong -- Megy, Karyn -- Grabherr, Manfred -- Ren, Quinghu -- Zdobnov, Evgeny M -- Lobo, Neil F -- Campbell, Kathryn S -- Brown, Susan E -- Bonaldo, Maria F -- Zhu, Jingsong -- Sinkins, Steven P -- Hogenkamp, David G -- Amedeo, Paolo -- Arensburger, Peter -- Atkinson, Peter W -- Bidwell, Shelby -- Biedler, Jim -- Birney, Ewan -- Bruggner, Robert V -- Costas, Javier -- Coy, Monique R -- Crabtree, Jonathan -- Crawford, Matt -- Debruyn, Becky -- Decaprio, David -- Eiglmeier, Karin -- Eisenstadt, Eric -- El-Dorry, Hamza -- Gelbart, William M -- Gomes, Suely L -- Hammond, Martin -- Hannick, Linda I -- Hogan, James R -- Holmes, Michael H -- Jaffe, David -- Johnston, J Spencer -- Kennedy, Ryan C -- Koo, Hean -- Kravitz, Saul -- Kriventseva, Evgenia V -- Kulp, David -- Labutti, Kurt -- Lee, Eduardo -- Li, Song -- Lovin, Diane D -- Mao, Chunhong -- Mauceli, Evan -- Menck, Carlos F M -- Miller, Jason R -- Montgomery, Philip -- Mori, Akio -- Nascimento, Ana L -- Naveira, Horacio F -- Nusbaum, Chad -- O'leary, Sinead -- Orvis, Joshua -- Pertea, Mihaela -- Quesneville, Hadi -- Reidenbach, Kyanne R -- Rogers, Yu-Hui -- Roth, Charles W -- Schneider, Jennifer R -- Schatz, Michael -- Shumway, Martin -- Stanke, Mario -- Stinson, Eric O -- Tubio, Jose M C -- Vanzee, Janice P -- Verjovski-Almeida, Sergio -- Werner, Doreen -- White, Owen -- Wyder, Stefan -- Zeng, Qiandong -- Zhao, Qi -- Zhao, Yongmei -- Hill, Catherine A -- Raikhel, Alexander S -- Soares, Marcelo B -- Knudson, Dennis L -- Lee, Norman H -- Galagan, James -- Salzberg, Steven L -- Paulsen, Ian T -- Dimopoulos, George -- Collins, Frank H -- Birren, Bruce -- Fraser-Liggett, Claire M -- Severson, David W -- 079059/Wellcome Trust/United Kingdom -- 5 R01 AI61576-2/AI/NIAID NIH HHS/ -- R01 AI059492/AI/NIAID NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-08/LM/NLM NIH HHS/ -- R37 AI024716/AI/NIAID NIH HHS/ -- UO1 AI50936/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Jun 22;316(5832):1718-23.

    Description: The conservation status of 845 zooxanthellate reef-building coral species was assessed by using International Union for Conservation of Nature Red List Criteria. Of the 704 species that could be assigned conservation status, 32.8% are in categories with elevated risk of extinction. Declines in abundance are associated with bleaching and diseases driven by elevated sea surface temperatures, with extinction risk further exacerbated by local-scale anthropogenic disturbances. The proportion of corals threatened with extinction has increased dramatically in recent decades and exceeds that of most terrestrial groups. The Caribbean has the largest proportion of corals in high extinction risk categories, whereas the Coral Triangle (western Pacific) has the highest proportion of species in all categories of elevated extinction risk. Our results emphasize the widespread plight of coral reefs and the urgent need to enact conservation measures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carpenter, Kent E -- Abrar, Muhammad -- Aeby, Greta -- Aronson, Richard B -- Banks, Stuart -- Bruckner, Andrew -- Chiriboga, Angel -- Cortes, Jorge -- Delbeek, J Charles -- Devantier, Lyndon -- Edgar, Graham J -- Edwards, Alasdair J -- Fenner, Douglas -- Guzman, Hector M -- Hoeksema, Bert W -- Hodgson, Gregor -- Johan, Ofri -- Licuanan, Wilfredo Y -- Livingstone, Suzanne R -- Lovell, Edward R -- Moore, Jennifer A -- Obura, David O -- Ochavillo, Domingo -- Polidoro, Beth A -- Precht, William F -- Quibilan, Miledel C -- Reboton, Clarissa -- Richards, Zoe T -- Rogers, Alex D -- Sanciangco, Jonnell -- Sheppard, Anne -- Sheppard, Charles -- Smith, Jennifer -- Stuart, Simon -- Turak, Emre -- Veron, John E N -- Wallace, Carden -- Weil, Ernesto -- Wood, Elizabeth -- New York, N.Y. -- Science. 2008 Jul 25;321(5888):560-3. doi: 10.1126/science.1159196.

    Description: Homologous sets of transcription factors direct conserved tissue-specific gene expression, yet transcription factor-binding events diverge rapidly between closely related species. We used hepatocytes from an aneuploid mouse strain carrying human chromosome 21 to determine, on a chromosomal scale, whether interspecies differences in transcriptional regulation are primarily directed by human genetic sequence or mouse nuclear environment. Virtually all transcription factor-binding locations, landmarks of transcription initiation, and the resulting gene expression observed in human hepatocytes were recapitulated across the entire human chromosome 21 in the mouse hepatocyte nucleus. Thus, in homologous tissues, genetic sequence is largely responsible for directing transcriptional programs; interspecies differences in epigenetic machinery, cellular environment, and transcription factors themselves play secondary roles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3717767/" 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/PMC3717767/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, Michael D -- Barbosa-Morais, Nuno L -- Schmidt, Dominic -- Conboy, Caitlin M -- Vanes, Lesley -- Tybulewicz, Victor L J -- Fisher, Elizabeth M C -- Tavare, Simon -- Odom, Duncan T -- 080174/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- G0601056/Medical Research Council/United Kingdom -- MC_U117527252/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Oct 17;322(5900):434-8. doi: 10.1126/science.1160930.

    Description: The diversity of tropical herbivorous insects has been explained as a direct function of plant species diversity. Testing that explanation, we reared 2857 flies from flowers and seeds of 24 species of plants from 34 neotropical sites. Samples yielded 52 morphologically similar species of flies and documented highly conserved patterns of specificity to host taxa and host parts. Widespread species of plants can support 13 species of flies. Within single populations of plants, we typically found one or more fly species specific to female flowers and multiple specialists on male flowers. We suggest that neotropical herbivorous insect diversity is not simply a function of plant taxonomic and architectural diversity, but also reflects the geographic distribution of hosts and the age and area of the neotropics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Condon, Marty A -- Scheffer, Sonja J -- Lewis, Matthew L -- Swensen, Susan M -- New York, N.Y. -- Science. 2008 May 16;320(5878):928-31. doi: 10.1126/science.1155832.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Cornell College, Mount Vernon, IA 52314, USA. mcondon@cornellcollege.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18487192" target="_blank"〉PubMed〈/a〉

    Description: Influenza virus evades prevailing natural and vaccine-induced immunity by accumulating antigenic change in the haemagglutinin surface protein. Linking amino acid substitutions in haemagglutinin epitopes to epidemiology has been problematic because of the scarcity of data connecting these scales. We use experiments on equine influenza virus to address this issue, quantifying how key parameters of viral establishment and shedding increase the probability of transmission with genetic distance between previously immunizing virus and challenge virus. Qualitatively similar patterns emerge from analyses based on antigenic distance and from a published human influenza study. Combination of the equine data and epidemiological models allows us to calculate the effective reproductive number of transmission as a function of relevant genetic change in the virus, illuminating the probability of influenza epidemics as a function of immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3800096/" 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/PMC3800096/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Park, Andrew W -- Daly, Janet M -- Lewis, Nicola S -- Smith, Derek J -- Wood, James L N -- Grenfell, Bryan T -- DP1-OD000490-01/OD/NIH HHS/ -- R01 GM083983/GM/NIGMS NIH HHS/ -- R01 GM083983-03/GM/NIGMS NIH HHS/ -- R01GM083983-02/GM/NIGMS NIH HHS/ -- R24 HD047879/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 30;326(5953):726-8. doi: 10.1126/science.1175980.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Odum School of Ecology, University of Georgia, Athens, GA 30602, USA. awpark@uga.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19900931" target="_blank"〉PubMed〈/a〉

    Description: Ichthyostega and Acanthostega are the earliest tetrapods known from multiple near-complete skeletons, with Acanthostega generally considered the more primitive. New material indicates differing ontogenetic trajectories for their forelimbs: In Ichthyostega, the pattern of muscle attachment processes on small humeri (upper arm bones) resembles that in "fish" members of the tetrapod stem group such as Tiktaalik, whereas large humeri approach (but fail to attain) the tetrapod crown-group condition; in Acanthostega, both small and large humeri exhibit the crown-group pattern. We infer that Ichthyostega underwent greater locomotory terrestrialization during ontogeny. The newly recognized primitive characteristics also suggest that Ichthyostega could be phylogenetically more basal than Acanthostega.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Callier, Viviane -- Clack, Jennifer A -- Ahlberg, Per E -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):364-7. doi: 10.1126/science.1167542.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University Museum of Zoology Cambridge, Downing Street, Cambridge CB2 3EJ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19372425" target="_blank"〉PubMed〈/a〉

The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.〈br /〉〈br /〉〈a

    Description: Kraft et al. (Reports, 24 October 2008, p. 580) used a variety of metrics describing the distribution of functional traits within a tropical forest community to demonstrate simultaneous environmental filtering and niche differentiation. We discuss how these results could have arisen from sampling design and statistical assumptions, suggesting alternative approaches that could better resolve these questions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lake, Jeffrey K -- Ostling, Annette -- New York, N.Y. -- Science. 2009 May 22;324(5930):1015; author reply 1015. doi: 10.1126/science.1169721.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Michigan, Kraus Natural Sciences Building, 830 North University, Ann Arbor, MI 48109, USA. lakejk@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19460986" target="_blank"〉PubMed〈/a〉

    Description: Genetic changes contributing to phenotypic differences within or between species have been identified for a handful of traits, but the relationship between alleles underlying intraspecific polymorphism and interspecific divergence is largely unknown. We found that noncoding changes in the tan gene, as well as changes linked to the ebony gene, contribute to pigmentation divergence between closely related Drosophila species. Moreover, we found that alleles linked to tan and ebony fixed in one Drosophila species also contribute to variation within another species, and that multiple genotypes underlie similar phenotypes even within the same population. These alleles appear to predate speciation, which suggests that standing genetic variation present in the common ancestor gave rise to both intraspecific polymorphism and interspecific divergence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wittkopp, Patricia J -- Stewart, Emma E -- Arnold, Lisa L -- Neidert, Adam H -- Haerum, Belinda K -- Thompson, Elizabeth M -- Akhras, Saleh -- Smith-Winberry, Gabriel -- Shefner, Laura -- New York, N.Y. -- Science. 2009 Oct 23;326(5952):540-4. doi: 10.1126/science.1176980.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA. wittkopp@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19900891" target="_blank"〉PubMed〈/a〉

    Description: The highly fragmented and distorted skull of the adult skeleton ARA-VP-6/500 includes most of the dentition and preserves substantial parts of the face, vault, and base. Anatomical comparisons and micro-computed tomography-based analysis of this and other remains reveal pre-Australopithecus hominid craniofacial morphology and structure. The Ardipithecus ramidus skull exhibits a small endocranial capacity (300 to 350 cubic centimeters), small cranial size relative to body size, considerable midfacial projection, and a lack of modern African ape-like extreme lower facial prognathism. Its short posterior cranial base differs from that of both Pan troglodytes and P. paniscus. Ar. ramidus lacks the broad, anteriorly situated zygomaxillary facial skeleton developed in later Australopithecus. This combination of features is apparently shared by Sahelanthropus, showing that the Mio-Pliocene hominid cranium differed substantially from those of both extant apes and Australopithecus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suwa, Gen -- Asfaw, Berhane -- Kono, Reiko T -- Kubo, Daisuke -- Lovejoy, C Owen -- White, Tim D -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):68e1-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University Museum, University of Tokyo, Hongo, Bunkyo-ku, Tokyo, 113-0033, Japan. suwa@um.u-tokyo.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810194" target="_blank"〉PubMed〈/a〉

The basic model assumptions of the three-quarter power scaling for resting metabolism and constancy of the mass-specific maintenance metabolism need to be reassessed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Makarieva, Anastassia M -- Gorshkov, Victor G -- Li, Bai-Lian -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1206; author reply 1206. doi: 10.1126/science.1171303.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Theoretical Physics Division, Petersburg Nuclear Physics Institute, Gatchina, St. Petersburg, Russia. elba@peterlink.ru〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19729641" target="_blank"〉PubMed〈/a〉

    Description: Proximate neural mechanisms that influence preferences for groups of a given size are almost wholly unknown. In the highly gregarious zebra finch (Estrildidae: Taeniopygia guttata), blockade of nonapeptide receptors by an oxytocin (OT) antagonist significantly reduced time spent with large groups and familiar social partners independent of time spent in social contact. Opposing effects were produced by central infusions of mesotocin (MT, avian homolog of OT). Most drug effects appeared to be female-specific. Across five estrildid finch species, species-typical group size correlates with nonapeptide receptor distributions in the lateral septum, and sociality in female zebra finches was reduced by OT antagonist infusions into the septum but not a control area. We propose that titration of sociality by MT represents a phylogenetically deep framework for the evolution of OT's female-specific roles in pair bonding and maternal functions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2862247/" 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/PMC2862247/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goodson, James L -- Schrock, Sara E -- Klatt, James D -- Kabelik, David -- Kingsbury, Marcy A -- MH062656/MH/NIMH NIH HHS/ -- R01 MH062656/MH/NIMH NIH HHS/ -- R01 MH062656-10/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):862-6. doi: 10.1126/science.1174929.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Indiana University, Bloomington, IN 47405, USA. jlgoodso@indiana.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19679811" target="_blank"〉PubMed〈/a〉

    Description: Species that are habitat specialists make up much of biodiversity, but the evolutionary factors that limit their distributions have rarely been considered. We show that in Drosophila, narrow and wide ranges of desiccation and cold resistance are closely associated with the distributions of specialist and generalist species, respectively. Furthermore, our data show that narrowly distributed tropical species consistently have low means and low genetic variation for these traits as compared with those of widely distributed species after phylogenetic correction. These results are unrelated to levels of neutral variation. Thus, specialist species may simply lack genetic variation in key traits, limiting their ability to adapt to conditions beyond their current range. We predict that such species are likely to be constrained in their evolutionary responses to future climate changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kellermann, Vanessa -- van Heerwaarden, Belinda -- Sgro, Carla M -- Hoffmann, Ary A -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1244-6. doi: 10.1126/science.1175443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Environmental Stress and Adaptation Research, Department of Genetics, University of Melbourne, Parkville, Melbourne 3010, Australia. vanessa.kellermann@biology.au.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19729654" target="_blank"〉PubMed〈/a〉

    Description: During evolution, novel phenotypes emerge through changes in gene expression, but the genetic basis is poorly understood. We compared the allele-specific expression of two yeast species and their hybrid, which allowed us to distinguish changes in regulatory sequences of the gene itself (cis) from changes in upstream regulatory factors (trans). Expression divergence between species was generally due to changes in cis. Divergence in trans reflected a differential response to the environment and explained the tendency of certain genes to diverge rapidly. Hybrid-specific expression, deviating from the parental range, occurred through novel cis-trans interactions or, more often, through modified trans regulation associated with environmental sensing. These results provide insights on the regulatory changes in cis and trans during the divergence of species and upon hybridization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tirosh, Itay -- Reikhav, Sharon -- Levy, Avraham A -- Barkai, Naama -- New York, N.Y. -- Science. 2009 May 1;324(5927):659-62. doi: 10.1126/science.1169766.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, Weizmann Institute of Science, Rehovot, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19407207" target="_blank"〉PubMed〈/a〉

    Description: Amphibians of the family Bufonidae contain high levels of skin compounds that both inhibit Na+- and K+-dependent adenosinetriphosphatase and antagonize the binding of ouabain to the enzyme. In species of Bufo and Atelopus, these compounds are relatively nonpolar bufodienolides, whereas Dendrophryniscus and Melanophryniscus contain more polar compounds of unknown structure. Skin extracts from 30 of 48 species of frogs representing an additional eight families contained relatively low levels of compounds that inhibit binding of ouabain to Na+,K+-adenosinetriphosphatase. The widespread occurrence of low levels of inhibitory compounds is consonant with the role for these compounds as physiological regulators of Na+,K+-adenosinetriphosphatase in amphibian skin; high levels in the Bufonidae probably also serve as a defense against some predators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Flier, J -- Edwards, M W -- Daly, J W -- Myers, C W -- New York, N.Y. -- Science. 1980 May 2;208(4443):503-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6245447" target="_blank"〉PubMed〈/a〉

    Description: Analysis of extracts of the bloodstream forms of Trypanosoma brucei showed that both DNA polymerase-alpha and DNA polymerase-beta activities were present. The detection of DNA polymerase-beta in T. brucei demonstrates the presence of this enzyme in unicellular organisms. DNA polymerase-beta is present also in Leishmania mexicana. The DNA polymerases in T. brucei are immunologically distinct from the host enzymes.

    Description: The indirect method of immunofluorescence was used to demonstrate the presence of amelogenins in the enameloid of teeth and dermal denticles of Chondrichthyes; in the enameloid of Teleostei and Amphibia; and in the enamel of Reptilia. Nonmammalian amelogenins are formed in the ectodermal cells of tooth organs and chemically are so similar to mammalian amelogenins that they interact with antiserum prepared from bovine enamel matrix.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herold, R C -- Graver, H T -- Christner, P -- New York, N.Y. -- Science. 1980 Mar 21;207(4437):1357-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6986656" target="_blank"〉PubMed〈/a〉
