    Genome streamlining in a cosmopolitan oceanic bacterium (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-08-20
    Beschreibung: The SAR11 clade consists of very small, heterotrophic marine alpha-proteobacteria that are found throughout the oceans, where they account for about 25% of all microbial cells. Pelagibacter ubique, the first cultured member of this clade, has the smallest genome and encodes the smallest number of predicted open reading frames known for a free-living microorganism. In contrast to parasitic bacteria and archaea with small genomes, P. ubique has complete biosynthetic pathways for all 20 amino acids and all but a few cofactors. P. ubique has no pseudogenes, introns, transposons, extrachromosomal elements, or inteins; few paralogs; and the shortest intergenic spacers yet observed for any cell.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giovannoni, Stephen J -- Tripp, H James -- Givan, Scott -- Podar, Mircea -- Vergin, Kevin L -- Baptista, Damon -- Bibbs, Lisa -- Eads, Jonathan -- Richardson, Toby H -- Noordewier, Michiel -- Rappe, Michael S -- Short, Jay M -- Carrington, James C -- Mathur, Eric J -- New York, N.Y. -- Science. 2005 Aug 19;309(5738):1242-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Oregon State University, Corvallis, OR 97331, USA. steve.giovannoni@oregonstate.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16109880" target="_blank"〉PubMed〈/a〉

    The molecular requirements for cytokinesis (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-03-19
    Beschreibung: After anaphase onset, animal cells build an actomyosin contractile ring that constricts the plasma membrane to generate two daughter cells connected by a cytoplasmic bridge. The bridge is ultimately severed to complete cytokinesis. Myriad techniques have been used to identify proteins that participate in cytokinesis in vertebrates, insects, and nematodes. A conserved core of about 20 proteins are individually involved with cytokinesis in most animal cells. These components are found in the contractile ring, on the central spindle, within the RhoA pathway, and on vesicles that expand the membrane and sever the bridge. Cytokinesis involves additional proteins, but they, or their requirement in cytokinesis, are not conserved among animal cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Glotzer, Michael -- New York, N.Y. -- Science. 2005 Mar 18;307(5716):1735-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute of Molecular Pathology, Dr. BohrGasse 7, A-1030 Vienna, Austria. mglotzer@imp.univie.ac.at〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15774750" target="_blank"〉PubMed〈/a〉

    SLC24A5, a putative cation exchanger, affects pigmentation in zebrafish and humans (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-12-17
    Beschreibung: Lighter variations of pigmentation in humans are associated with diminished number, size, and density of melanosomes, the pigmented organelles of melanocytes. Here we show that zebrafish golden mutants share these melanosomal changes and that golden encodes a putative cation exchanger slc24a5 (nckx5) that localizes to an intracellular membrane, likely the melanosome or its precursor. The human ortholog is highly similar in sequence and functional in zebrafish. The evolutionarily conserved ancestral allele of a human coding polymorphism predominates in African and East Asian populations. In contrast, the variant allele is nearly fixed in European populations, is associated with a substantial reduction in regional heterozygosity, and correlates with lighter skin pigmentation in admixed populations, suggesting a key role for the SLC24A5 gene in human pigmentation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamason, Rebecca L -- Mohideen, Manzoor-Ali P K -- Mest, Jason R -- Wong, Andrew C -- Norton, Heather L -- Aros, Michele C -- Jurynec, Michael J -- Mao, Xianyun -- Humphreville, Vanessa R -- Humbert, Jasper E -- Sinha, Soniya -- Moore, Jessica L -- Jagadeeswaran, Pudur -- Zhao, Wei -- Ning, Gang -- Makalowska, Izabela -- McKeigue, Paul M -- O'donnell, David -- Kittles, Rick -- Parra, Esteban J -- Mangini, Nancy J -- Grunwald, David J -- Shriver, Mark D -- Canfield, Victor A -- Cheng, Keith C -- CA73935/CA/NCI NIH HHS/ -- EY11308/EY/NEI NIH HHS/ -- HD37572/HD/NICHD NIH HHS/ -- HD40179/HD/NICHD NIH HHS/ -- HG002154/HG/NHGRI NIH HHS/ -- HL077910/HL/NHLBI NIH HHS/ -- RR017441/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2005 Dec 16;310(5755):1782-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jake Gittlen Cancer Research Foundation, Department of Pathology, The Pennsylvania State University College of Medicine, Hershey, PA 17033, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16357253" target="_blank"〉PubMed〈/a〉

    Multiple causes of high extinction risk in large mammal species (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-07-23
    Beschreibung: Many large animal species have a high risk of extinction. This is usually thought to result simply from the way that species traits associated with vulnerability, such as low reproductive rates, scale with body size. In a broad-scale analysis of extinction risk in mammals, we find two additional patterns in the size selectivity of extinction risk. First, impacts of both intrinsic and environmental factors increase sharply above a threshold body mass around 3 kilograms. Second, whereas extinction risk in smaller species is driven by environmental factors, in larger species it is driven by a combination of environmental factors and intrinsic traits. Thus, the disadvantages of large size are greater than generally recognized, and future loss of large mammal biodiversity could be far more rapid than expected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cardillo, Marcel -- Mace, Georgina M -- Jones, Kate E -- Bielby, Jon -- Bininda-Emonds, Olaf R P -- Sechrest, Wes -- Orme, C David L -- Purvis, Andy -- New York, N.Y. -- Science. 2005 Aug 19;309(5738):1239-41.

    How obesity causes diabetes: not a tall tale (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-01-22
    Beschreibung: The epidemic of obesity-associated diabetes is a major crisis in modern societies, in which food is plentiful and exercise is optional. The biological basis of this problem has been explored from evolutionary and mechanistic perspectives. Evolutionary theories, focusing on the potential survival advantages of "thrifty" genes that are now maladaptive, are of great interest but are inherently speculative and difficult to prove. Mechanistic studies have revealed numerous fat-derived molecules and a link to inflammation that, together, are hypothesized to underlie the obesity-diabetes connection and thereby represent prospective targets for therapeutic intervention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lazar, Mitchell A -- New York, N.Y. -- Science. 2005 Jan 21;307(5708):373-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Endocrinology, Diabetes, and Metabolism, Department of Medicine, and The Penn Diabetes Center, University of Pennsylvania School of Medicine, Philadelphia, PA 19104-6149, USA. lazar@mail.med.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15662001" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 2005-02-19
    Beschreibung: We describe several fossils referable to Gomphos elkema from deposits close to the Paleocene-Eocene boundary at Tsagan Khushu, Mongolia. Gomphos shares a suite of cranioskeletal characters with extant rabbits, hares, and pikas but retains a primitive dentition and jaw compared to its modern relatives. Phylogenetic analysis supports the position of Gomphos as a stem lagomorph and excludes Cretaceous taxa from the crown radiation of placental mammals. Our results support the hypothesis that rodents and lagomorphs radiated during the Cenozoic and diverged from other placental mammals close to the Cretaceous-Tertiary boundary.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Asher, Robert J -- Meng, Jin -- Wible, John R -- McKenna, Malcolm C -- Rougier, Guillermo W -- Dashzeveg, Demberlyn -- Novacek, Michael J -- New York, N.Y. -- Science. 2005 Feb 18;307(5712):1091-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Museum fur Naturkunde, Humboldt Universitat, Invalidenstrasse 43, 10115 Berlin, Germany. robert.asher@museum.hu-berlin.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15718468" target="_blank"〉PubMed〈/a〉

    A human-specific gene in microglia (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-09-10
    Beschreibung: Recent studies have shown multiple differences between humans and apes in sialic acid (Sia) biology, including Siglecs (Sia-recognizing-Ig-superfamily lectins). Comparisons with the chimpanzee genome indicate that human SIGLEC11 emerged through human-specific gene conversion by an adjacent pseudogene. Conversion involved 5 cent untranslated sequences and the Sia-recognition domain. This human protein shows reduced binding relative to the ancestral form but recognizes oligosialic acids, which are enriched in the brain. SIGLEC11 is expressed in human but not in chimpanzee brain microglia. Further studies will determine if this event was related to the evolution of Homo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hayakawa, Toshiyuki -- Angata, Takashi -- Lewis, Amanda L -- Mikkelsen, Tarjei S -- Varki, Nissi M -- Varki, Ajit -- R01GM32373/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 9;309(5741):1693.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Glycobiology Research and Training Center, University of California at San Diego, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16151003" target="_blank"〉PubMed〈/a〉

    Postsecretory hydrolysis of nectar sucrose and specialization in ant/plant mutualism (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-04-23
    Beschreibung: 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.

    Marine fish egg hydration is aquaporin-mediated (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-02-01
    Beschreibung: The positive buoyancy of marine fish eggs in sea water, allowed by hydration of the oocyte, is critical for their survival and dispersion in the ocean. We isolated an aquaporin, SaAQP1o, that belongs to a unique subfamily of aquaporin-1-like channels specifically evolved in teleosts and mainly expressed in the ovary. We further show that hormone-induced fish oocyte hydration is a highly controlled process based on the interplay between protein hydrolysis and the translocation of SaAQP1o to the plasma membrane, indicating a specialized physiological role for this aquaporin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fabra, Mercedes -- Raldua, Demetrio -- Power, Deborah M -- Deen, Peter M T -- Cerda, Joan -- New York, N.Y. -- Science. 2005 Jan 28;307(5709):545.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center of Aquaculture-Institut de Recerca i Tecnologia Agroalimentaries, Tarragona, Spain, and Reference Center in Aquaculture, Barcelona, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15681377" target="_blank"〉PubMed〈/a〉

    Selection on heritable phenotypic plasticity in a wild bird population (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-10-15
    Beschreibung: Theoretical and laboratory research suggests that phenotypic plasticity can evolve under selection. However, evidence for its evolutionary potential from the wild is lacking. We present evidence from a Dutch population of great tits (Parus major) for variation in individual plasticity in the timing of reproduction, and we show that this variation is heritable. Selection favoring highly plastic individuals has intensified over a 32-year period. This temporal trend is concurrent with climate change causing a mismatch between the breeding times of the birds and their caterpillar prey. Continued selection on plasticity can act to alleviate this mismatch.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nussey, Daniel H -- Postma, Erik -- Gienapp, Phillip -- Visser, Marcel E -- New York, N.Y. -- Science. 2005 Oct 14;310(5746):304-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Netherlands Institute of Ecology (NIOO-KNAW), Post Office Box 40, 6666 ZG Heteren, Netherlands. d.h.nussey@sms.ed.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16224020" target="_blank"〉PubMed〈/a〉

    Horsfield's hawk-cuckoo nestlings simulate multiple gapes for begging (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-04-30
    Beschreibung: Nestlings of some brood parasitic birds evict hosts' eggs and young soon after hatching, thereby avoiding discrimination by hosts while monopolizing parental care. Eviction carries a cost, however, because lone parasitic nestlings attract a reduced provisioning rate. Here we describe a form of visual signaling used by the evicting Horsfield's hawk-cuckoo (Cuculus fugax) to obtain sufficient food. The chick displays a gape-colored patch on the wing to the host parents as they deliver food, simulating the gaping display of more than one nestling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanaka, Keita D -- Ueda, Keisuke -- New York, N.Y. -- Science. 2005 Apr 29;308(5722):653.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Life Sciences, Rikkyo University, 3-34-1 Nishi-Ikebukuro, Toshima, 171-8501 Tokyo, Japan. keita@zaf.att.ne.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15860618" target="_blank"〉PubMed〈/a〉

    A homolog of Drosophila grainy head is essential for epidermal integrity in mice (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-04-16
    Beschreibung: The Drosophila cuticle is essential for maintaining the surface barrier defenses of the fly. Integral to cuticle resilience is the transcription factor grainy head, which regulates production of the enzyme required for covalent cross-linking of the cuticular structural components. We report that formation and maintenance of the epidermal barrier in mice are dependent on a mammalian homolog of grainy head, Grainy head-like 3. Mice lacking this factor display defective skin barrier function and deficient wound repair, accompanied by reduced expression of transglutaminase 1, the key enzyme involved in cross-linking the structural components of the superficial epidermis. These findings suggest that the functional mechanisms involving protein cross-linking that maintain the epidermal barrier and induce tissue repair are conserved across 700 million years of evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ting, Stephen B -- Caddy, Jacinta -- Hislop, Nikki -- Wilanowski, Tomasz -- Auden, Alana -- Zhao, Lin-Lin -- Ellis, Sarah -- Kaur, Pritinder -- Uchida, Yoshikazu -- Holleran, Walter M -- Elias, Peter M -- Cunningham, John M -- Jane, Stephen M -- P01 HL53749-03/HL/NHLBI NIH HHS/ -- P01-AR39448/AR/NIAMS NIH HHS/ -- P30 CA 21765/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2005 Apr 15;308(5720):411-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rotary Bone Marrow Research Laboratories, c/o Royal Melbourne Hospital Post Office, Grattan Street, Parkville, Victoria, Australia 3050.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15831758" target="_blank"〉PubMed〈/a〉

    Beschreibung: The unicellular conifer tracheid should have greater flow resistance per length (resistivity) than the multicellular angiosperm vessel, because its high-resistance end-walls are closer together. However, tracheids and vessels had comparable resistivities for the same diameter, despite tracheids being over 10 times shorter. End-wall pits of tracheids averaged 59 times lower flow resistance on an area basis than vessel pits, owing to the unique torus-margo structure of the conifer pit membrane. The evolution of this membrane was as hydraulically important as that of vessels. Without their specialized pits, conifers would have 38 times the flow resistance, making conifer-dominated ecosystems improbable in an angiosperm world.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pittermann, Jarmila -- Sperry, John S -- Hacke, Uwe G -- Wheeler, James K -- Sikkema, Elzard H -- New York, N.Y. -- Science. 2005 Dec 23;310(5756):1924.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Utah, 257S 1400E, Salt Lake City, UT 84112, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16373568" target="_blank"〉PubMed〈/a〉

    Noise in gene expression: origins, consequences, and control (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-09-24
    Beschreibung: Genetically identical cells and organisms exhibit remarkable diversity even when they have identical histories of environmental exposure. Noise, or variation, in the process of gene expression may contribute to this phenotypic variability. Recent studies suggest that this noise has multiple sources, including the stochastic or inherently random nature of the biochemical reactions of gene expression. In this review, we summarize noise terminology and comment on recent investigations into the sources, consequences, and control of noise in gene expression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1360161/" 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/PMC1360161/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raser, Jonathan M -- O'Shea, Erin K -- GM51377/GM/NIGMS NIH HHS/ -- R01 GM051377/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 23;309(5743):2010-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Scientist Training Program, University of California-San Francisco, 600 16th Street, GH-S472D, San Francisco, CA 94143-2240, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16179466" target="_blank"〉PubMed〈/a〉

    The effects of artificial selection on the maize genome (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-05-28
    Beschreibung: Domestication promotes rapid phenotypic evolution through artificial selection. We investigated the genetic history by which the wild grass teosinte (Zea mays ssp. parviglumis) was domesticated into modern maize (Z. mays ssp. mays). Analysis of single-nucleotide polymorphisms in 774 genes indicates that 2 to 4% of these genes experienced artificial selection. The remaining genes retain evidence of a population bottleneck associated with domestication. Candidate selected genes with putative function in plant growth are clustered near quantitative trait loci that contribute to phenotypic differences between maize and teosinte. If we assume that our sample of genes is representative, approximately 1200 genes throughout the maize genome have been affected by artificial selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wright, Stephen I -- Bi, Irie Vroh -- Schroeder, Steve G -- Yamasaki, Masanori -- Doebley, John F -- McMullen, Michael D -- Gaut, Brandon S -- New York, N.Y. -- Science. 2005 May 27;308(5726):1310-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of California, Irvine, CA 92697, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15919994" target="_blank"〉PubMed〈/a〉

    Publikationsdatum: 2005-03-26
    Beschreibung: The distal human intestine represents an anaerobic bioreactor programmed with an enormous population of bacteria, dominated by relatively few divisions that are highly diverse at the strain/subspecies level. This microbiota and its collective genomes (microbiome) provide us with genetic and metabolic attributes we have not been required to evolve on our own, including the ability to harvest otherwise inaccessible nutrients. New studies are revealing how the gut microbiota has coevolved with us and how it manipulates and complements our biology in ways that are mutually beneficial. We are also starting to understand how certain keystone members of the microbiota operate to maintain the stability and functional adaptability of this microbial organ.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Backhed, Fredrik -- Ley, Ruth E -- Sonnenburg, Justin L -- Peterson, Daniel A -- Gordon, Jeffrey I -- New York, N.Y. -- Science. 2005 Mar 25;307(5717):1915-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genome Sciences, Washington University School of Medicine, St. Louis, MO 63108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15790844" target="_blank"〉PubMed〈/a〉

    The selective cause of an ancient adaptation (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-01-18
    Beschreibung: Phylogenetic analysis reveals that the use of nicotinamide adenine dinucleotide phosphate (NADP) by prokaryotic isocitrate dehydrogenase (IDH) arose around the time eukaryotic mitochondria first appeared, about 3.5 billion years ago. We replaced the wild-type gene that encodes the NADP-dependent IDH of Escherichia coli with an engineered gene that possesses the ancestral NAD-dependent phenotype. The engineered enzyme is disfavored during competition for acetate. The selection intensifies in genetic backgrounds where other sources of reduced NADP have been removed. A survey of sequenced prokaryotic genomes reveals that those genomes that encode isocitrate lyase, which is essential for growth on acetate, always have an NADP-dependent IDH. Those with only an NAD-dependent IDH never have isocitrate lyase. Hence, the NADP dependence of prokaryotic IDH is an ancient adaptation to anabolic demand for reduced NADP during growth on acetate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhu, Guoping -- Golding, G Brian -- Dean, Antony M -- GM060611/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Feb 25;307(5713):1279-82.

    A molecular phylogeny for bats illuminates biogeography and the fossil record (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-02-01
    Beschreibung: Bats make up more than 20% of extant mammals, yet their evolutionary history is largely unknown because of a limited fossil record and conflicting or incomplete phylogenies. Here, we present a highly resolved molecular phylogeny for all extant bat families. Our results support the hypothesis that megabats are nested among four major microbat lineages, which originated in the early Eocene [52 to 50 million years ago (Mya)], coincident with a significant global rise in temperature, increase in plant diversity and abundance, and the zenith of Tertiary insect diversity. Our data suggest that bats originated in Laurasia, possibly in North America, and that three of the major microbat lineages are Laurasian in origin, whereas the fourth is Gondwanan. Combining principles of ghost lineage analysis with molecular divergence dates, we estimate that the bat fossil record underestimates (unrepresented basal branch length, UBBL) first occurrences by, on average, 73% and that the sum of missing fossil history is 61%.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teeling, Emma C -- Springer, Mark S -- Madsen, Ole -- Bates, Paul -- O'brien, Stephen J -- Murphy, William J -- N01-CO-12400/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 2005 Jan 28;307(5709):580-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genomic Diversity, Basic Research Program, SAIC-Frederick, Inc., National Cancer Institute, Frederick, MD 21702, USA. emma.teeling@ucd.ie〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15681385" target="_blank"〉PubMed〈/a〉

    Beschreibung: The ivory-billed woodpecker (Campephilus principalis), long suspected to be extinct, has been rediscovered in the Big Woods region of eastern Arkansas. Visual encounters during 2004 and 2005, and analysis of a video clip from April 2004, confirm the existence of at least one male. Acoustic signatures consistent with Campephilus display drums also have been heard from the region. Extensive efforts to find birds away from the primary encounter site remain unsuccessful, but potential habitat for a thinly distributed source population is vast (over 220,000 hectares).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fitzpatrick, John W -- Lammertink, Martjan -- Luneau, M David Jr -- Gallagher, Tim W -- Harrison, Bobby R -- Sparling, Gene M -- Rosenberg, Kenneth V -- Rohrbaugh, Ronald W -- Swarthout, Elliott C H -- Wrege, Peter H -- Swarthout, Sara Barker -- Dantzker, Marc S -- Charif, Russell A -- Barksdale, Timothy R -- Remsen, J V Jr -- Simon, Scott D -- Zollner, Douglas -- New York, N.Y. -- Science. 2005 Jun 3;308(5727):1460-2.

    The role of social groups in the persistence of learned fear (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-07-30
    Beschreibung: Classical fear conditioning investigates how animals learn to associate environmental stimuli with an aversive event. We examined how the mechanisms of fear conditioning apply when humans learn to associate social ingroup and outgroup members with a fearful event, with the goal of advancing our understanding of basic learning theory and social group interaction. Primates more readily associate stimuli from certain fear-relevant natural categories, such as snakes, with a negative outcome relative to stimuli from fear-irrelevant categories, such as birds. We assessed whether this bias in fear conditioning extends to social groups defined by race. Our results indicate that individuals from a racial group other than one's own are more readily associated with an aversive stimulus than individuals of one's own race, among both white and black Americans. This prepared fear response might be reduced by close, positive interracial contact.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsson, Andreas -- Ebert, Jeffrey P -- Banaji, Mahzarin R -- Phelps, Elizabeth A -- 1RO1MH57672/MH/NIMH NIH HHS/ -- 5R01MH068447/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2005 Jul 29;309(5735):785-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, New York University, 6 Washington Place, New York, NY 10003, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16051800" target="_blank"〉PubMed〈/a〉

    Courting bird sings with stridulating wing feathers (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-07-30
    Beschreibung: In birds and other vertebrates, most acoustic signals are produced pneumatically by moving air through a vocal apparatus. Here we describe a unique mechanism used to produce a tonal acoustic signal in vertebrates. Video recordings of the courtship displays of male Club-winged Manakins, Machaeropterus deliciosus, reveal that males produce sustained harmonic tones through interactions among oscillating secondary wing feathers. This mechanism of sound production shows morphological and mechanistic convergence with arthropod stridulation. Intersexual selection for production of a nonvocal courtship song has led to major morphological, functional, and likely physiological modifications in the wing of this flying bird.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bostwick, Kimberly S -- Prum, Richard O -- New York, N.Y. -- Science. 2005 Jul 29;309(5735):736.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Cornell University, Ithaca, NY 14850, USA. ksb6@cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16051789" target="_blank"〉PubMed〈/a〉

    A cost of long-term memory in Drosophila (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-05-21
    Beschreibung: Two distinct forms of consolidated associative memory are known in Drosophila: long-term memory and so-called anesthesia-resistant memory. Long-term memory is more stable, but unlike anesthesia-resistant memory, its formation requires protein synthesis. We show that flies induced to form long-term memory become more susceptible to extreme stress (such as desiccation). In contrast, induction of anesthesia-resistant memory had no detectable effect on desiccation resistance. This finding may help to explain why evolution has maintained anesthesia-resistant memory as another form of consolidated memory, distinct from long-term memory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mery, Frederic -- Kawecki, Tadeusz J -- New York, N.Y. -- Science. 2005 May 20;308(5725):1148.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Ecology and Evolution, Department of Biology, University of Fribourg, Chemin du Musee 10, CH-1700 Fribourg, Switzerland. frederic.mery@unifr.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15905396" target="_blank"〉PubMed〈/a〉

    On the origin of leprosy (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-05-17
    Beschreibung: Leprosy, a chronic human disease with potentially debilitating neurological consequences, results from infection with Mycobacterium leprae. This unculturable pathogen has undergone extensive reductive evolution, with half of its genome now occupied by pseudogenes. Using comparative genomics, we demonstrated that all extant cases of leprosy are attributable to a single clone whose dissemination worldwide can be retraced from analysis of very rare single-nucleotide polymorphisms. The disease seems to have originated in Eastern Africa or the Near East and spread with successive human migrations. Europeans or North Africans introduced leprosy into West Africa and the Americas within the past 500 years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Monot, Marc -- Honore, Nadine -- Garnier, Thierry -- Araoz, Romulo -- Coppee, Jean-Yves -- Lacroix, Celine -- Sow, Samba -- Spencer, John S -- Truman, Richard W -- Williams, Diana L -- Gelber, Robert -- Virmond, Marcos -- Flageul, Beatrice -- Cho, Sang-Nae -- Ji, Baohong -- Paniz-Mondolfi, Alberto -- Convit, Jacinto -- Young, Saroj -- Fine, Paul E -- Rasolofo, Voahangy -- Brennan, Patrick J -- Cole, Stewart T -- R01-AI47197-01A1/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2005 May 13;308(5724):1040-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Unite de Genetique Moleculaire Bacterienne, Institut Pasteur, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15894530" target="_blank"〉PubMed〈/a〉

    Comparative genomics of trypanosomatid parasitic protozoa (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-07-16
    Beschreibung: 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〉

    Assortative mating in sympatric host races of the European corn borer (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-04-12
    Beschreibung: Although a growing body of work supports the plausibility of sympatric speciation in animals, the practical difficulties of directly quantifying reproductive isolation between diverging taxa remain an obstacle to analyzing this process. We used a combination of genetic and biogeochemical markers to produce a direct field estimate of assortative mating in phytophagous insect populations. We show that individuals of the same insect species, the European corn borer Ostrinia nubilalis, that develop on different host plants can display almost absolute reproductive isolation-the proportion of assortative mating was 〉95%-even in the absence of temporal or spatial isolation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malausa, Thibaut -- Bethenod, Marie-Therese -- Bontemps, Arnaud -- Bourguet, Denis -- Cornuet, Jean-Marie -- Ponsard, Sergine -- New York, N.Y. -- Science. 2005 Apr 8;308(5719):258-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire Dynamique de la Biodiversite, Universite P.

    Web-spinning caterpillar stalks snails (2005)

    Publikationsdatum: 2005-07-26
    Beschreibung: Moths and butterflies compose one of the most diverse insect orders, but they are overwhelmingly herbivorous. Less than 0.2% are specialized predators, indicating that lepidopteran feeding habits are highly constrained. We report a Hawaiian caterpillar that specializes on snails, a unique food source requiring an unusual feeding strategy. The caterpillar uses silk to restrain live prey. All caterpillars have silk glands, but none are known to use silk in this spiderlike fashion. Considering the canalization of caterpillar diets, evolution to attack and feed on snails is an anomaly. Hawaii s isolation and consequently disharmonic biota likely promote evolutionary experiments that occur nowhere else.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rubinoff, Daniel -- Haines, William P -- New York, N.Y. -- Science. 2005 Jul 22;309(5734):575.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉310 Gilmore Hall, Department of Plant and Environmental Protection Sciences, 3050 Maile Way, University of Hawaii, Honolulu, HI 96822, USA. rubinoff@hawaii.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16040699" target="_blank"〉PubMed〈/a〉

    U-Pb ages from the neoproterozoic Doushantuo Formation, China (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-02-26
    Beschreibung: U-Pb zircon dates from volcanic ash beds within the Doushantuo Formation (China) indicate that its deposition occurred between 635 and 551 million years ago. The base records termination of the global-scale Marinoan glaciation and is coeval with similar dated rocks from Namibia, indicating synchronous deglaciation. Carbon isotopic and sequence-stratigraphic data imply that the spectacular animal fossils of the Doushantuo Formation are for the most part younger than 580 million years old. The uppermost Doushantuo Formation contains a pronounced negative carbonate carbon isotopic excursion, which we interpret as a global event at circa 551 million years ago.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Condon, Daniel -- Zhu, Maoyan -- Bowring, Samuel -- Wang, Wei -- Yang, Aihua -- Jin, Yugan -- New York, N.Y. -- Science. 2005 Apr 1;308(5718):95-8.

    An unusual marine crocodyliform from the Jurassic-Cretaceous boundary of Patagonia (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-11-12
    Beschreibung: Remains of the marine crocodyliform Dakosaurus andiniensis from western South America reveal a lineage that drastically deviated from the skull morphology that characterizes marine crocodyliforms. The snout and lower jaw are extremely robust, short, and high and only bear a few large teeth with serrated edges (resembling those of some terrestrial carnivorous archosaurs). This unusual morphology contrasts with the long and gracile snout and lower jaws bearing numerous teeth, which are present in the closest relatives of D. andiniensis (and interpreted as indicating feeding on small fish or mollusks). Thus, the morphological diversity of pelagic marine crocodyliforms was wider than had been thought.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gasparini, Zulma -- Pol, Diego -- Spalletti, Luis A -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):70-3.
