    Seychelles fisheries country profile : 1990-1994. (2006)
    Victoria: Seychelles Fishing Authority
    Details
    Publication Date: 2021-05-19
    Description: Seychelles is composed of over 100 islands with a land area of approximately 455 km², centred close to 4°30'S and 55°30'E. The combined coastline is approximately 600 km long, the oceanic shelf totals about 50 000 km² and the Exclusive Economic Zone (EEZ) is over 1 370 000 km². The total population (1994 census) stands at just under 74 000. in 1994, the population registered a growth rate of 2.2%. The GDP (1994) was SR 2373.8 million, fisheries representing 4.8% of this sum. Licensing agreements for foreign fishing activities provided a yearly revenue of SR8 million. Port Victoria is seen as a prime centre for tuna fishing operations in the Indian Ocean. In the artisanal fishery just under 900 persons are working. The largest contributor to catch by vessel type are the traditional whaler vessels representing 47.8% of the total catch. Over 66.3% of the catch is by the handline method. Carangidae representing 24% and Lutjanidae 19% of total landings. There are six specific objectives to the fisheries sector policy, which aims as resource development and maximisation of potential benefits. Nearshore fishery resources are considered to be heavily exploited, however opportunities exist around the distant islands and in deeper waters off the Mahe plateau shelf. Aquaculture of molluscs and prawns is being developed and carried out. The main constraints to development are seen as the lack of skilled manpower and foreign exchange.

    Aggresomes and autophagy generate sites for virus replication (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-13
    Description: The replication of many viruses is associated with specific intracellular compartments called virus factories or virioplasm. These are thought to provide a physical scaffold to concentrate viral components and thereby increase the efficiency of replication. The formation of virus replication sites often results in rearrangement of cellular membranes and reorganization of the cytoskeleton. Similar rearrangements are seen in cells in response to protein aggregation, where aggresomes and autophagosomes are produced to facilitate protein degradation. Here I review the evidence that some viruses induce aggresomes and autophagosomes to generate sites of replication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wileman, Thomas -- New York, N.Y. -- Science. 2006 May 12;312(5775):875-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Medicine, Health Policy and Practice, University of East Anglia, Norwich NR4 7TJ, UK. t.wileman@uea.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16690857" target="_blank"〉PubMed〈/a〉

    Comment on "Stability via asynchrony in Drosophila metapopulations with low migration rates" (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-21
    Description: Dey and Joshi (Reports, 21 April 2006, p. 434) studied replicate laboratory populations of Drosophila and reported that low migration led to asynchrony among subpopulations. We argue that this unexpected outcome may be due to variation in the initial size of the subpopulations and uncontrolled stochasticity in the experiments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ranta, Esa -- Kaitala, Veijo -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):420; author reply 420.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Integrative Ecology Unit, Department of Biological and Environmental Sciences, P.O.

    Coevolved crypts and exocrine glands support mutualistic bacteria in fungus-growing ants (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-10
    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〉

    Group competition, reproductive leveling, and the evolution of human altruism (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-13
    Description: Humans behave altruistically in natural settings and experiments. A possible explanation-that groups with more altruists survive when groups compete-has long been judged untenable on empirical grounds for most species. But there have been no empirical tests of this explanation for humans. My empirical estimates show that genetic differences between early human groups are likely to have been great enough so that lethal intergroup competition could account for the evolution of altruism. Crucial to this process were distinctive human practices such as sharing food beyond the immediate family, monogamy, and other forms of reproductive leveling. These culturally transmitted practices presuppose advanced cognitive and linguistic capacities, possibly accounting for the distinctive forms of altruism found in our species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowles, Samuel -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1569-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA, and Universita di Siena, 17 Piazza San Francesco, Siena, Italy. bowles@santafe.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158320" target="_blank"〉PubMed〈/a〉

    Emergence of drug-resistant influenza virus: population dynamical considerations (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-22
    Description: Given the considerable challenges to the rapid development of an effective vaccine against influenza, antiviral agents will play an important role as a first-line defense if a new pandemic occurs. The large-scale use of drugs for chemoprophylaxis and treatment will impose strong selection for the evolution of drug-resistant strains. The ensuing transmission of those strains could substantially limit the effectiveness of the drugs as a first-line defense. Summarizing recent data on the rate at which the treatment of influenza infection generates resistance de novo and on the transmission fitness of resistant virus, we discuss possible implications for the epidemiological spread of drug resistance in the context of an established population dynamic model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Regoes, Roland R -- Bonhoeffer, Sebastian -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):389-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Integrative Biology, ETH Zurich, ETH Zentrum CHN K12.1, Universitatsstrasse 16, CH 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16627735" target="_blank"〉PubMed〈/a〉

    Gene regulatory networks and the evolution of animal body plans (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-14
    Description: Development of the animal body plan is controlled by large gene regulatory networks (GRNs), and hence evolution of body plans must depend upon change in the architecture of developmental GRNs. However, these networks are composed of diverse components that evolve at different rates and in different ways. Because of the hierarchical organization of developmental GRNs, some kinds of change affect terminal properties of the body plan such as occur in speciation, whereas others affect major aspects of body plan morphology. A notable feature of the paleontological record of animal evolution is the establishment by the Early "Cambrian of virtually all phylum-level body plans. We identify a class of GRN component, the kernels" of the network, which, because of their developmental role and their particular internal structure, are most impervious to change. Conservation of phyletic body plans may have been due to the retention since pre-Cambrian time of GRN kernels, which underlie development of major body parts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davidson, Eric H -- Erwin, Douglas H -- HD37105/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):796-800.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology 156-29, California Institute of Technology, Pasadena, CA 91125, USA. davidson@caltech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469913" target="_blank"〉PubMed〈/a〉

    Long-distance dispersal of plants (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-12
    Description: Long-distance dispersal (LDD) of plants poses challenges to research because it involves rare events driven by complex and highly stochastic processes. The current surge of renewed interest in LDD, motivated by growing recognition of its critical importance for natural populations and communities and for humanity, promises an improved, quantitatively derived understanding of LDD. To gain deep insights into the patterns, mechanisms, causes, and consequences of LDD, we must look beyond the standard dispersal vectors and the mean trend of the distribution of dispersal distances. "Nonstandard" mechanisms such as extreme climatic events and generalized LDD vectors seem to hold the greatest explanatory power for the drastic deviations from the mean trend, deviations that make the nearly impossible LDD a reality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nathan, Ran -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):786-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Movement Ecology Laboratory, Department of Evolution, Systematics and Ecology, Alexander Silberman Institute of Life Sciences, Hebrew University of Jerusalem, Givat Ram, 91904 Jerusalem, Israel. rnathan@cc.huji.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902126" target="_blank"〉PubMed〈/a〉

    alphaE-catenin controls cerebral cortical size by regulating the hedgehog signaling pathway (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-03-18
    Description: During development, cells monitor and adjust their rates of accumulation to produce organs of predetermined size. We show here that central nervous system-specific deletion of the essential adherens junction gene, alphaE-catenin, causes abnormal activation of the hedgehog pathway, resulting in shortening of the cell cycle, decreased apoptosis, and cortical hyperplasia. We propose that alphaE-catenin connects cell-density-dependent adherens junctions with the developmental hedgehog pathway and that this connection may provide a negative feedback loop controlling the size of developing cerebral cortex.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2556178/" 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/PMC2556178/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lien, Wen-Hui -- Klezovitch, Olga -- Fernandez, Tania E -- Delrow, Jeff -- Vasioukhin, Valeri -- P41 RR011823/RR/NCRR NIH HHS/ -- P41 RR011823-128171/RR/NCRR NIH HHS/ -- R01 CA098161/CA/NCI NIH HHS/ -- R01 CA098161-01A1/CA/NCI NIH HHS/ -- R01 CA098161-02/CA/NCI NIH HHS/ -- R01 CA098161-03/CA/NCI NIH HHS/ -- R01 CA098161-04/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1609-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Human Biology, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16543460" target="_blank"〉PubMed〈/a〉

    The molecular architecture of axonemes revealed by cryoelectron tomography (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-19
    Description: Eukaryotic flagella and cilia are built on a 9 + 2 array of microtubules plus 〉250 accessory proteins, forming a biological machine called the axoneme. Here we describe the three-dimensional structure of rapidly frozen axonemes from Chlamydomonas and sea urchin sperm, using cryoelectron tomography and image processing to focus on the motor enzyme dynein. Our images suggest a model for the way dynein generates force to slide microtubules. They also reveal two dynein linkers that may provide "hard-wiring" to coordinate motor enzyme action, both circumferentially and along the axoneme. Periodic densities were also observed inside doublet microtubules; these may contribute to doublet stability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicastro, Daniela -- Schwartz, Cindi -- Pierson, Jason -- Gaudette, Richard -- Porter, Mary E -- McIntosh, J Richard -- 2R37-GM55667/GM/NIGMS NIH HHS/ -- RR 000592/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2006 Aug 18;313(5789):944-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for 3D Electron Microscopy of Cells, Department of Molecular, Cellular, and Developmental Biology, CB 347, University of Colorado, Boulder, CO 80309-0347, USA. nicastro@colorado.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16917055" target="_blank"〉PubMed〈/a〉

    Stability via asynchrony in Drosophila metapopulations with low migration rates (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-22
    Description: Very few experimental studies have examined how migration rate affects metapopulation dynamics and stability. We studied the dynamics of replicate laboratory metapopulations of Drosophila under different migration rates. Low migration stabilized metapopulation dynamics, while promoting unstable subpopulation dynamics, by inducing asynchrony among neighboring subpopulations. High migration synchronized subpopulation dynamics, thereby destabilizing the metapopulations. Contrary to some theoretical predictions, increased migration did not affect average population size. Simulations based on a simple non-species-specific population growth model captured most features of the data, which suggests that our results are generalizable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dey, Sutirth -- Joshi, Amitabh -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):434-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Evolutionary Biology Laboratory, Evolutionary & Organismal Biology Unit, Jawaharlal Nehru Centre for Advanced Scientific Research, Jakkur P.O., Bangalore 560 064, India.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16627743" target="_blank"〉PubMed〈/a〉

    Evolutionary history of Salmonella typhi (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-25
    Description: For microbial pathogens, phylogeographic differentiation seems to be relatively common. However, the neutral population structure of Salmonella enterica serovar Typhi reflects the continued existence of ubiquitous haplotypes over millennia. In contrast, clinical use of fluoroquinolones has yielded at least 15 independent gyrA mutations within a decade and stimulated clonal expansion of haplotype H58 in Asia and Africa. Yet, antibiotic-sensitive strains and haplotypes other than H58 still persist despite selection for antibiotic resistance. Neutral evolution in Typhi appears to reflect the asymptomatic carrier state, and adaptive evolution depends on the rapid transmission of phenotypic changes through acute infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2652035/" 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/PMC2652035/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roumagnac, Philippe -- Weill, Francois-Xavier -- Dolecek, Christiane -- Baker, Stephen -- Brisse, Sylvain -- Chinh, Nguyen Tran -- Le, Thi Anh Hong -- Acosta, Camilo J -- Farrar, Jeremy -- Dougan, Gordon -- Achtman, Mark -- 076962/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Nov 24;314(5803):1301-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Infektionsbiologie, Department of Molecular Biology, Chariteplatz 1, 10117 Berlin, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17124322" target="_blank"〉PubMed〈/a〉

    Dual infection with HIV and malaria fuels the spread of both diseases in sub-Saharan Africa (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-13
    Description: Mounting evidence has revealed pathological interactions between HIV and malaria in dually infected patients, but the public health implications of the interplay have remained unclear. A transient almost one-log elevation in HIV viral load occurs during febrile malaria episodes; in addition, susceptibility to malaria is enhanced in HIV-infected patients. A mathematical model applied to a setting in Kenya with an adult population of roughly 200,000 estimated that, since 1980, the disease interaction may have been responsible for 8,500 excess HIV infections and 980,000 excess malaria episodes. Co-infection might also have facilitated the geographic expansion of malaria in areas where HIV prevalence is high. Hence, transient and repeated increases in HIV viral load resulting from recurrent co-infection with malaria may be an important factor in promoting the spread of HIV in sub-Saharan Africa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abu-Raddad, Laith J -- Patnaik, Padmaja -- Kublin, James G -- P30 AI 27757/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1603-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Statistical Center for HIV/AIDS Research and Prevention, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA. laith@scharp.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158329" target="_blank"〉PubMed〈/a〉

    Sequencing and analysis of Neanderthal genomic DNA (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-18
    Description: Our knowledge of Neanderthals is based on a limited number of remains and artifacts from which we must make inferences about their biology, behavior, and relationship to ourselves. Here, we describe the characterization of these extinct hominids from a new perspective, based on the development of a Neanderthal metagenomic library and its high-throughput sequencing and analysis. Several lines of evidence indicate that the 65,250 base pairs of hominid sequence so far identified in the library are of Neanderthal origin, the strongest being the ascertainment of sequence identities between Neanderthal and chimpanzee at sites where the human genomic sequence is different. These results enabled us to calculate the human-Neanderthal divergence time based on multiple randomly distributed autosomal loci. Our analyses suggest that on average the Neanderthal genomic sequence we obtained and the reference human genome sequence share a most recent common ancestor approximately 706,000 years ago, and that the human and Neanderthal ancestral populations split approximately 370,000 years ago, before the emergence of anatomically modern humans. Our finding that the Neanderthal and human genomes are at least 99.5% identical led us to develop and successfully implement a targeted method for recovering specific ancient DNA sequences from metagenomic libraries. This initial analysis of the Neanderthal genome advances our understanding of the evolutionary relationship of Homo sapiens and Homo neanderthalensis and signifies the dawn of Neanderthal genomics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2583069/" 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/PMC2583069/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noonan, James P -- Coop, Graham -- Kudaravalli, Sridhar -- Smith, Doug -- Krause, Johannes -- Alessi, Joe -- Chen, Feng -- Platt, Darren -- Paabo, Svante -- Pritchard, Jonathan K -- Rubin, Edward M -- 1-F32-GM074367/GM/NIGMS NIH HHS/ -- HL066681/HL/NHLBI NIH HHS/ -- R01 HG002772/HG/NHGRI NIH HHS/ -- R01 HG002772-01/HG/NHGRI NIH HHS/ -- R01 HG002772-1/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 17;314(5802):1113-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Energy Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17110569" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-03-11
    Description: A biosynthetic approach was developed to control and probe cooperativity in multiunit biomotor assemblies by linking molecular motors to artificial protein scaffolds. This approach provides precise control over spatial and elastic coupling between motors. Cooperative interactions between monomeric kinesin-1 motors attached to protein scaffolds enhance hydrolysis activity and microtubule gliding velocity. However, these interactions are not influenced by changes in the elastic properties of the scaffold, distinguishing multimotor transport from that powered by unorganized monomeric motors. These results highlight the role of supramolecular architecture in determining mechanisms of collective transport.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diehl, Michael R -- Zhang, Kechun -- Lee, Heun Jin -- Tirrell, David A -- New York, N.Y. -- Science. 2006 Mar 10;311(5766):1468-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Chemistry and Chemical Engineering, California Institute of Technology, Pasadena, CA 91125, USA. diehl@rice.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16527982" target="_blank"〉PubMed〈/a〉

    Bacterial small-molecule signaling pathways (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-25
    Description: Bacteria use diverse small molecules for extra- and intracellular signaling. They scan small-molecule mixtures to access information about both their extracellular environment and their intracellular physiological status, and based on this information, they continuously interpret their circumstances and react rapidly to changes. Bacteria must integrate extra- and intracellular signaling information to mount appropriate responses to changes in their environment. We review recent research into two fundamental bacterial small-molecule signaling pathways: extracellular quorum-sensing signaling and intracellular cyclic dinucleotide signaling.

    An aegialodontid upper molar and the evolution of mammal dentition (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-26
    Description: The most obvious key synapomorphy of the therian mammals is the tribosphenic pattern of their molars. Tribosphenic teeth are capable of both shearing and grinding, which substantially increase effectiveness of food processing and, in turn, permit evolution of a wide range of dietary specializations. Functional tribospheny developed repeatedly during mammalian evolution but was successful only in the Boreosphenida. The earliest stage in the development of boreosphenidan tribospheny has remained poorly understood, being documented only by lower molars of aegialodontids. Here, we report a known upper molar of an aegialodontid mammal, Kielantherium, from the Early Cretaceous of Mongolia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lopatin, Alexey V -- Averianov, Alexander O -- New York, N.Y. -- Science. 2006 Aug 25;313(5790):1092.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Paleontological Institute, Russian Academy of Sciences, Profsojuznaya ul. 123, Moscow 117997, Russia. alopat@paleo.ru〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16931755" target="_blank"〉PubMed〈/a〉

    Five rules for the evolution of cooperation (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-13
    Description: Cooperation is needed for evolution to construct new levels of organization. Genomes, cells, multicellular organisms, social insects, and human society are all based on cooperation. Cooperation means that selfish replicators forgo some of their reproductive potential to help one another. But natural selection implies competition and therefore opposes cooperation unless a specific mechanism is at work. Here I discuss five mechanisms for the evolution of cooperation: kin selection, direct reciprocity, indirect reciprocity, network reciprocity, and group selection. For each mechanism, a simple rule is derived that specifies whether natural selection can lead to cooperation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3279745/" 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/PMC3279745/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nowak, Martin A -- 1R01GM078986-01/GM/NIGMS NIH HHS/ -- R01 GM078986/GM/NIGMS NIH HHS/ -- R01 GM078986-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1560-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program for Evolutionary Dynamics, Department of Organismic and Evolutionary Biology, and Department of Mathematics, Harvard University, Cambridge, MA 02138, USA. martin_nowak@harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158317" target="_blank"〉PubMed〈/a〉

    An equivalence principle for the incorporation of favorable mutations in asexual populations (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-03-18
    Description: Rapid evolution of asexual populations, such as that of cancer cells or of microorganisms developing drug resistance, can include the simultaneous spread of distinct beneficial mutations. We demonstrate that evolution in such cases is driven by the fitness effects and appearance times of only a small minority of favorable mutations. The complexity of the mutation-selection process is thereby greatly reduced, and much of the evolutionary dynamics can be encapsulated in two parameters-an effective selection coefficient and effective rate of beneficial mutations. We confirm this theoretical finding and estimate the effective parameters for evolving populations of fluorescently labeled Escherichia coli. The effective parameters constitute a simple description and provide a natural standard for comparing adaptation between species and across environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hegreness, Matthew -- Shoresh, Noam -- Hartl, Daniel -- Kishony, Roy -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1615-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bauer Center for Genomics Research, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16543462" target="_blank"〉PubMed〈/a〉

However, there is an exact analytical solution for the expected cluster distribution under the proposed null model of density-independent growth in a patchy landscape. Reanalysis of the data shows that the system is not in a critical state but confirms the importance of a mutualism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alonso, David -- Pascual, Mercedes -- New York, N.Y. -- Science. 2006 Sep 22;313(5794):1739; author reply 1739.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecology and Evolutionary Biology, University of Michigan, 830 North University Avenue, Ann Arbor, MI 48109-1048, USA. dalonso@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16990534" target="_blank"〉PubMed〈/a〉

    Clonal adaptive radiation in a constant environment (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-11
    Description: The evolution of new combinations of bacterial properties contributes to biodiversity and the emergence of new diseases. We investigated the capacity for bacterial divergence with a chemostat culture of Escherichia coli. A clonal population radiated into more than five phenotypic clusters within 26 days, with multiple variations in global regulation, metabolic strategies, surface properties, and nutrient permeability pathways. Most isolates belonged to a single ecotype, and neither periodic selection events nor ecological competition for a single niche prevented an adaptive radiation with a single resource. The multidirectional exploration of fitness space is an underestimated ingredient to bacterial success even in unstructured environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maharjan, Ram -- Seeto, Shona -- Notley-McRobb, Lucinda -- Ferenci, Thomas -- New York, N.Y. -- Science. 2006 Jul 28;313(5786):514-7.

    Publication Date: 2006-09-09
    Description: The origin and possible antiquity of faunas at deep-sea hydrothermal vents and seeps have been debated since their discovery. We used the fossil record of seep mollusks to show that the living seep genera have significantly longer geologic ranges than the marine mollusks in general, but have ranges similar to those of deep-sea taxa, suggesting that seep faunas may be shaped by the factors that drive the evolution of life in the deep sea in general. Our data indicate that deep-sea anoxic/dysoxic events did not affect seep faunas, casting doubt on the suggested anoxic nature and/or global extent of these events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kiel, Steffen -- Little, Crispin T S -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1429-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Earth and Environment, University of Leeds, Leeds LS2 9JT, UK. steffen.kiel@gmx.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16960004" target="_blank"〉PubMed〈/a〉

    Phytophthora genome sequences uncover evolutionary origins and mechanisms of pathogenesis (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-02
    Description: Draft genome sequences have been determined for the soybean pathogen Phytophthora sojae and the sudden oak death pathogen Phytophthora ramorum. Oomycetes such as these Phytophthora species share the kingdom Stramenopila with photosynthetic algae such as diatoms, and the presence of many Phytophthora genes of probable phototroph origin supports a photosynthetic ancestry for the stramenopiles. Comparison of the two species' genomes reveals a rapid expansion and diversification of many protein families associated with plant infection such as hydrolases, ABC transporters, protein toxins, proteinase inhibitors, and, in particular, a superfamily of 700 proteins with similarity to known oomycete avirulence genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tyler, Brett M -- Tripathy, Sucheta -- Zhang, Xuemin -- Dehal, Paramvir -- Jiang, Rays H Y -- Aerts, Andrea -- Arredondo, Felipe D -- Baxter, Laura -- Bensasson, Douda -- Beynon, Jim L -- Chapman, Jarrod -- Damasceno, Cynthia M B -- Dorrance, Anne E -- Dou, Daolong -- Dickerman, Allan W -- Dubchak, Inna L -- Garbelotto, Matteo -- Gijzen, Mark -- Gordon, Stuart G -- Govers, Francine -- Grunwald, Niklaus J -- Huang, Wayne -- Ivors, Kelly L -- Jones, Richard W -- Kamoun, Sophien -- Krampis, Konstantinos -- Lamour, Kurt H -- Lee, Mi-Kyung -- McDonald, W Hayes -- Medina, Monica -- Meijer, Harold J G -- Nordberg, Eric K -- Maclean, Donald J -- Ospina-Giraldo, Manuel D -- Morris, Paul F -- Phuntumart, Vipaporn -- Putnam, Nicholas H -- Rash, Sam -- Rose, Jocelyn K C -- Sakihama, Yasuko -- Salamov, Asaf A -- Savidor, Alon -- Scheuring, Chantel F -- Smith, Brian M -- Sobral, Bruno W S -- Terry, Astrid -- Torto-Alalibo, Trudy A -- Win, Joe -- Xu, Zhanyou -- Zhang, Hongbin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Boore, Jeffrey L -- BB/C509123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1261-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Virginia Bioinformatics Institute, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061, USA. bmtyler@vt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946064" target="_blank"〉PubMed〈/a〉

    Description: Latimer et al. (Reports, 9 September 2005, p. 1722) used an approximate likelihood function to estimate parameters of Hubbell's neutral model of biodiversity. Reanalysis with the exact likelihood not only yields different estimates but also shows that two similar likelihood maxima for very different parameter combinations can occur. This reveals a limitation of using species abundance data to gain insight into speciation and dispersal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Etienne, Rampal S -- Latimer, Andrew M -- Silander, John A Jr -- Cowling, Richard M -- New York, N.Y. -- Science. 2006 Feb 3;311(5761):610.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Community and Conservation Ecology Group, University of Groningen, Box 14, 9750 AA Haren, The Netherlands. r.s.etienne@rug.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16456064" target="_blank"〉PubMed〈/a〉

    Lower Cambrian vendobionts from China and early diploblast evolution (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-06
    Description: Ediacaran assemblages immediately predate the Cambrian explosion of metazoans and should have played a crucial role in this radiation. Their wider relationships, however, have remained refractory and difficult to integrate with early metazoan phylogeny. Here, we describe a frondlike fossil, Stromatoveris (S. psygmoglena sp. nov.), from the Lower Cambrian Chengjiang Lagerstatte (Yunnan, China) that is strikingly similar to Ediacaran vendobionts. The exquisite preservation reveals closely spaced branches, probably ciliated, that appear to represent precursors of the diagnostic comb rows of ctenophores. Therefore, this finding has important implications for the early evolution of this phylum and related diploblasts, some of which independently evolved a frondose habit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shu, D-G -- Morris, S Conway -- Han, J -- Li, Y -- Zhang, X-L -- Hua, H -- Zhang, Z-F -- Liu, J-N -- Guo, J-F -- Yao, Y -- Yasui, K -- New York, N.Y. -- Science. 2006 May 5;312(5774):731-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Early Life Institute and Key Laboratory of Continental Dynamics, Northwest University, Xi'an 710069, China. elidgshu@nwu.edu.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16675697" target="_blank"〉PubMed〈/a〉

    JETLAG resets the Drosophila circadian clock by promoting light-induced degradation of TIMELESS (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-24
    Description: Organisms ranging from bacteria to humans synchronize their internal clocks to daily cycles of light and dark. Photic entrainment of the Drosophila clock is mediated by proteasomal degradation of the clock protein TIMELESS (TIM). We have identified mutations in jetlag-a gene coding for an F-box protein with leucine-rich repeats-that result in reduced light sensitivity of the circadian clock. Mutant flies show rhythmic behavior in constant light, reduced phase shifts in response to light pulses, and reduced light-dependent degradation of TIM. Expression of JET along with the circadian photoreceptor cryptochrome (CRY) in cultured S2R cells confers light-dependent degradation onto TIM, thereby reconstituting the acute response + of the circadian clock to light in a cell culture system. Our results suggest that JET is essential for resetting the clock by transmitting light signals from CRY to TIM.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2767177/" 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/PMC2767177/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koh, Kyunghee -- Zheng, Xiangzhong -- Sehgal, Amita -- NS048471/NS/NINDS NIH HHS/ -- R01 NS048471/NS/NINDS NIH HHS/ -- R01 NS048471-02/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2006 Jun 23;312(5781):1809-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Neuroscience, University of Pennsylvania School of Medicine, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16794082" target="_blank"〉PubMed〈/a〉

    Late-Neoproterozoic deep-ocean oxygenation and the rise of animal life (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-13
    Description: Because animals require oxygen, an increase in late-Neoproterozoic oxygen concentrations has been suggested as a stimulus for their evolution. The iron content of deep-sea sediments shows that the deep ocean was anoxic and ferruginous before and during the Gaskiers glaciation 580 million years ago and that it became oxic afterward. The first known members of the Ediacara biota arose shortly after the Gaskiers glaciation, suggesting a causal link between their evolution and this oxygenation event. A prolonged stable oxic environment may have permitted the emergence of bilateral motile animals some 25 million years later.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Canfield, Don E -- Poulton, Simon W -- Narbonne, Guy M -- New York, N.Y. -- Science. 2007 Jan 5;315(5808):92-5.

    The primary cilium as the cell's antenna: signaling at a sensory organelle (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-05
    Description: Almost every vertebrate cell has a specialized cell surface projection called a primary cilium. Although these structures were first described more than a century ago, the full scope of their functions remains poorly understood. Here, we review emerging evidence that in addition to their well-established roles in sight, smell, and mechanosensation, primary cilia are key participants in intercellular signaling. This new appreciation of primary cilia as cellular antennae that sense a wide variety of signals could help explain why ciliary defects underlie such a wide range of human disorders, including retinal degeneration, polycystic kidney disease, Bardet-Biedl syndrome, and neural tube defects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Singla, Veena -- Reiter, Jeremy F -- R21 DK069423/DK/NIDDK NIH HHS/ -- R21DK69423/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2006 Aug 4;313(5787):629-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Developmental and Stem Cell Biology, and Diabetes Center, University of California, San Francisco, CA 94143-0525, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16888132" target="_blank"〉PubMed〈/a〉

    FG-rich repeats of nuclear pore proteins form a three-dimensional meshwork with hydrogel-like properties (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-04
    Description: Nuclear pore complexes permit rapid passage of cargoes bound to nuclear transport receptors, but otherwise suppress nucleocytoplasmic fluxes of inert macromolecules 〉/=30 kilodaltons. To explain this selectivity, a sieve structure of the permeability barrier has been proposed that is created through reversible cross-linking between Phe and Gly (FG)-rich nucleoporin repeats. According to this model, nuclear transport receptors overcome the size limit of the sieve and catalyze their own nuclear pore-passage by a competitive disruption of adjacent inter-repeat contacts, which transiently opens adjoining meshes. Here, we found that phenylalanine-mediated inter-repeat interactions indeed cross-link FG-repeat domains into elastic and reversible hydrogels. Furthermore, we obtained evidence that such hydrogel formation is required for viability in yeast.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frey, Steffen -- Richter, Ralf P -- Gorlich, Dirk -- New York, N.Y. -- Science. 2006 Nov 3;314(5800):815-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zentrum fur Molekulare Biologie der Universitat Heidelberg (ZMBH), INF 282, D-69120 Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17082456" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2006-09-02
    Description: On the basis of new information from the 10th specimen of Archaeopteryx, Mayr et al. (Reports, 2 December 2005, p. 1483) suggested that birds, or avian flight, originated twice. We investigate the statistical support for this phylogenetic hypothesis and show that it is no better supported by available morphological character data than the hypothesis of a single avian origin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corfe, Ian J -- Butler, Richard J -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1238; author reply 1238.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, University of Bristol, Wills Memorial Building, Queens Road, Bristol, BS8 1RJ, UK. ian.corfe@bristol.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946054" target="_blank"〉PubMed〈/a〉

    Evolutionary paths underlying flower color variation in Antirrhinum (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-19
    Description: To understand evolutionary paths connecting diverse biological forms, we defined a three-dimensional genotypic space separating two flower color morphs of Antirrhinum. A hybrid zone between morphs showed a steep cline specifically at genes controlling flower color differences, indicating that these loci are under selection. Antirrhinum species with diverse floral phenotypes formed a U-shaped cloud within the genotypic space. We propose that this cloud defines an evolutionary path that allows flower color to evolve while circumventing less-adaptive regions. Hybridization between morphs located in different arms of the U-shaped path yields low-fitness genotypes, accounting for the observed steep clines at hybrid zones.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whibley, Annabel C -- Langlade, Nicolas B -- Andalo, Christophe -- Hanna, Andrew I -- Bangham, Andrew -- Thebaud, Christophe -- Coen, Enrico -- New York, N.Y. -- Science. 2006 Aug 18;313(5789):963-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell and Developmental Biology, John Innes Centre, Colney Lane, Norwich NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16917061" target="_blank"〉PubMed〈/a〉

    Out of the tropics: evolutionary dynamics of the latitudinal diversity gradient (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-07
    Description: The evolutionary dynamics underlying the latitudinal gradient in biodiversity have been controversial for over a century. Using a spatially explicit approach that incorporates not only origination and extinction but immigration, a global analysis of genera and subgenera of marine bivalves over the past 11 million years supports an "out of the tropics" model, in which taxa preferentially originate in the tropics and expand toward the poles without losing their tropical presence. The tropics are thus both a cradle and a museum of biodiversity, contrary to the conceptual dichotomy dominant since 1974; a tropical diversity crisis would thus have profound evolutionary effects at all latitudes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jablonski, David -- Roy, Kaustuv -- Valentine, James W -- New York, N.Y. -- Science. 2006 Oct 6;314(5796):102-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geophysical Sciences, University of Chicago, 5734 South Ellis Avenue, Chicago, IL 60637, USA. djablons@uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17023653" target="_blank"〉PubMed〈/a〉

    Genomic islands and the ecology and evolution of Prochlorococcus (2006)

    Details
    Publication Date: 2006-03-25
    Description: Prochlorococcus ecotypes are a useful system for exploring the origin and function of diversity among closely related microbes. The genetic variability between phenotypically distinct strains that differ by less that 1% in 16S ribosomal RNA sequences occurs mostly in genomic islands. Island genes appear to have been acquired in part by phage-mediated lateral gene transfer, and some are differentially expressed under light and nutrient stress. Furthermore, genome fragments directly recovered from ocean ecosystems indicate that these islands are variable among cooccurring Prochlorococcus cells. Genomic islands in this free-living photoautotroph share features with pathogenicity islands of parasitic bacteria, suggesting a general mechanism for niche differentiation in microbial species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coleman, Maureen L -- Sullivan, Matthew B -- Martiny, Adam C -- Steglich, Claudia -- Barry, Kerrie -- Delong, Edward F -- Chisholm, Sallie W -- New York, N.Y. -- Science. 2006 Mar 24;311(5768):1768-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts Institute of Technology, Department of Civil and Environmental Engineering, 15 Vassar Street, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16556843" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-05-20
    Description: Large-scale comparative genomics in harness with proteomics has substantiated fundamental features of eukaryote cellular evolution. The evolutionary trajectory of modern eukaryotes is distinct from that of prokaryotes. Data from many sources give no direct evidence that eukaryotes evolved by genome fusion between archaea and bacteria. Comparative genomics shows that, under certain ecological settings, sequence loss and cellular simplification are common modes of evolution. Subcellular architecture of eukaryote cells is in part a physical-chemical consequence of molecular crowding; subcellular compartmentation with specialized proteomes is required for the efficient functioning of proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurland, C G -- Collins, L J -- Penny, D -- New York, N.Y. -- Science. 2006 May 19;312(5776):1011-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbial Ecology, Lund University, Lund, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16709776" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-05-13
    Description: The interface between an infectious agent and its host represents the ultimate battleground for survival: The microbe must secure a niche for replication, whereas the host must limit the pathogen's advance. Among the host's arsenal of antimicrobial factors, the type 1 interferons (IFNs) induce potent defense mechanisms against viruses and are key in the host-virus standoff. Viruses have evolved multiple tricks to avoid the immediate antiviral effects of IFNs and, in turn, hosts have adapted use of this innate cytokine system to galvanize multiple additional layers of immune defense. The plasticity that exists in these interactions provides us with a lesson in detente.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garcia-Sastre, Adolfo -- Biron, Christine A -- P01AI52106/AI/NIAID NIH HHS/ -- P01AI58113/AI/NIAID NIH HHS/ -- R01AI46954/AI/NIAID NIH HHS/ -- R01AI55677/AI/NIAID NIH HHS/ -- R01CA41268/CA/NCI NIH HHS/ -- U19AI62623/AI/NIAID NIH HHS/ -- U54AI57158/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 May 12;312(5775):879-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Mount Sinai School of Medicine, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16690858" target="_blank"〉PubMed〈/a〉

    Human lineage-specific amplification, selection, and neuronal expression of DUF1220 domains (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-02
    Description: Extreme gene duplication is a major source of evolutionary novelty. A genome-wide survey of gene copy number variation among human and great ape lineages revealed that the most striking human lineage-specific amplification was due to an unknown gene, MGC8902, which is predicted to encode multiple copies of a protein domain of unknown function (DUF1220). Sequences encoding these domains are virtually all primate-specific, show signs of positive selection, and are increasingly amplified generally as a function of a species' evolutionary proximity to humans, where the greatest number of copies (212) is found. DUF1220 domains are highly expressed in brain regions associated with higher cognitive function, and in brain show neuron-specific expression preferentially in cell bodies and dendrites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Popesco, Magdalena C -- Maclaren, Erik J -- Hopkins, Janet -- Dumas, Laura -- Cox, Michael -- Meltesen, Lynne -- McGavran, Loris -- Wyckoff, Gerald J -- Sikela, James M -- AA11853/AA/NIAAA NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1304-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Medical Genetics, University of Colorado at Denver and Health Sciences Center, Aurora, CO 80045, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946073" target="_blank"〉PubMed〈/a〉

    Description: Mathematical models predict that the future of the multidrug-resistant tuberculosis epidemic will depend on the fitness cost of drug resistance. We show that in laboratory-derived mutants of Mycobacterium tuberculosis, rifampin resistance is universally associated with a competitive fitness cost and that this cost is determined by the specific resistance mutation and strain genetic background. In contrast, we demonstrate that prolonged patient treatment can result in multidrug-resistant strains with no fitness defect and that strains with low- or no-cost resistance mutations are also the most frequent among clinical isolates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gagneux, Sebastien -- Long, Clara Davis -- Small, Peter M -- Van, Tran -- Schoolnik, Gary K -- Bohannan, Brendan J M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1944-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Infectious Diseases and Geographic Medicine, Stanford University, Stanford, CA 94305, USA. sgagneux@systemsbiology.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809538" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-01-18
    Description: In contrast to current models, fluorescence resonance energy transfer measurements using a single-cell imaging assay with fluorescent forms of PER and TIM showed that these proteins bind rapidly and persist in the cytoplasm while gradually accumulating in discrete foci. After approximately 6 hours, complexes abruptly dissociated, as PER and TIM independently moved to the nucleus in a narrow time frame. The per(L) mutation delayed nuclear accumulation in vivo and in our cultured cell system, but without affecting rates of PER/TIM assembly or dissociation. This finding points to a previously unrecognized form of temporal regulation that underlies the periodicity of the circadian clock.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, Pablo -- Saez, Lino -- Young, Michael W -- GM54339/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Jan 13;311(5758):226-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, Rockefeller University, 1230 York Avenue, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16410523" target="_blank"〉PubMed〈/a〉

    Publication Date: 2006-09-30
    Description: The family of Hox genes, which number 4 to 48 per genome depending on the animal, control morphologies on the main body axis of nearly all metazoans. The conventional wisdom is that Hox genes are arranged in chromosomal clusters in colinear order with their expression patterns on the body axis. However, recent evidence has shown that Hox gene clusters are fragmented, reduced, or expanded in many animals-findings that correlate with interesting morphological changes in evolution. Hox gene clusters also contain many noncoding RNAs, such as intergenic regulatory transcripts and evolutionarily conserved microRNAs, some of whose developmental functions have recently been explored.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lemons, Derek -- McGinnis, William -- R37 HD028315/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 29;313(5795):1918-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Cell and Developmental Biology, University of California San Diego, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17008523" target="_blank"〉PubMed〈/a〉

    Description: The endemic species richness on Madagascar, relative to landmass area, is unparalleled in the world. Many organisms on the island have restricted geographical ranges. A comprehensive hypothesis explaining the evolution of this microendemism has yet to be developed. Using an analysis of watersheds in the context of Quaternary climatic shifts, we provide a new mechanistic model to explain the process of explosive speciation on the island. River catchments with sources at relatively low elevations were zones of isolation and hence led to the speciation of locally endemic taxa, whereas those at higher elevations were zones of retreat and dispersion and hence contain proportionately lower levels of microendemism. These results provide a framework for biogeographic and phylogeographic studies, as well as a basis for prioritizing conservation actions of the remaining natural forest habitats on the island.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilme, Lucienne -- Goodman, Steven M -- Ganzhorn, Jorg U -- New York, N.Y. -- Science. 2006 May 19;312(5776):1063-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Missouri Botanical Garden, Boite Postale 3391, Antananarivo (101), Madagascar.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16709785" target="_blank"〉PubMed〈/a〉

    The Ste5 scaffold allosterically modulates signaling output of the yeast mating pathway (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-21
    Description: Scaffold proteins organize signaling proteins into pathways and are often viewed as passive assembly platforms. We found that the Ste5 scaffold has a more active role in the yeast mating pathway: A fragment of Ste5 allosterically activated autophosphorylation of the mitogen-activated protein kinase Fus3. The resulting form of Fus3 is partially active-it is phosphorylated on only one of two key residues in the activation loop. Unexpectedly, at a systems level, autoactivated Fus3 appears to have a negative regulatory role, promoting Ste5 phosphorylation and a decrease in pathway transcriptional output. Thus, scaffolds not only direct basic pathway connectivity but can precisely tune quantitative pathway input-output properties.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bhattacharyya, Roby P -- Remenyi, Attila -- Good, Matthew C -- Bashor, Caleb J -- Falick, Arnold M -- Lim, Wendell A -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):822-6.

    G protein signaling in yeast: new components, new connections, new compartments (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-12-02
    Description: Signaling by cell surface receptors and heterotrimeric guanine nucleotide-binding proteins (G proteins) is one of the most exhaustively studied processes in the cell but remains a major focus of molecular pharmacology research. The pheromone-response system in yeast (see the Connections Map at Science's Signal Transduction Knowledge Environment) has provided numerous major advances in our understanding of G protein signaling and regulation. However, the basic features of this prototypical pathway have remained largely unchanged since the mid-1990s. New tools available in yeast are beginning to uncover new pathway components and interactions and have revealed signaling in unexpected locations within the cell.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slessareva, Janna E -- Dohlman, Henrik G -- P01-GM065533/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 1;314(5804):1412-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of North Carolina, Chapel Hill, NC 27599-7260, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17138892" target="_blank"〉PubMed〈/a〉

    Predictability and preparedness in influenza control (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-22
    Description: The threat of pandemic human influenza looms as we survey the ongoing avian influenza pandemic and wonder if and when it will jump species. What are the risks and how can we plan? The nub of the problem lies in the inherent variability of the virus, which makes prediction difficult. However, it is not impossible; mathematical models can help determine and quantify critical parameters and thresholds in the relationships of those parameters, even if the relationships are nonlinear and obscure to simple reasoning. Mathematical models can derive estimates for the levels of drug stockpiles needed to buy time, how and when to modify vaccines, whom to target with vaccines and drugs, and when to enforce quarantine measures. Regardless, the models used for pandemic planning must be tested, and for this we must continue to gather data, not just for exceptional scenarios but also for seasonal influenza.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Derek J -- DP1-OD000490-01/OD/NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):392-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Cambridge, Downing Street, Cambridge, CB2 3EJ, UK. dsmith@zoo.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16627736" target="_blank"〉PubMed〈/a〉

    The late Miocene radiation of modern Felidae: a genetic assessment (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-10
    Description: Modern felid species descend from relatively recent (〈11 million years ago) divergence and speciation events that produced successful predatory carnivores worldwide but that have confounded taxonomic classifications. A highly resolved molecular phylogeny with divergence dates for all living cat species, derived from autosomal, X-linked, Y-linked, and mitochondrial gene segments (22,789 base pairs) and 16 fossil calibrations define eight principal lineages produced through at least 10 intercontinental migrations facilitated by sea-level fluctuations. A ghost lineage analysis indicates that available felid fossils underestimate (i.e., unrepresented basal branch length) first occurrence by an average of 76%, revealing a low representation of felid lineages in paleontological remains. The phylogenetic performance of distinct gene classes showed that Y-chromosome segments are appreciably more informative than mitochondrial DNA, X-linked, or autosomal genes in resolving the rapid Felidae species radiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, Warren E -- Eizirik, Eduardo -- Pecon-Slattery, Jill -- Murphy, William J -- Antunes, Agostinho -- Teeling, Emma -- O'Brien, Stephen J -- N01-CO-12400/CO/NCI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):73-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genomic Diversity, National Cancer Institute, Frederick, MD 21702-1201, USA. johnsonw@ncifcrf.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400146" target="_blank"〉PubMed〈/a〉
