    Assembling the 20 Gb white spruce (Picea glauca) genome from whole-genome shotgun sequencing data (2013)
    Oxford University Press
    Details
    Publication Date: 2013-06-06
    Description: White spruce ( Picea glauca ) is a dominant conifer of the boreal forests of North America, and providing genomics resources for this commercially valuable tree will help improve forest management and conservation efforts. Sequencing and assembling the large and highly repetitive spruce genome though pushes the boundaries of the current technology. Here, we describe a whole-genome shotgun sequencing strategy using two Illumina sequencing platforms and an assembly approach using the ABySS software. We report a 20.8 giga base pairs draft genome in 4.9 million scaffolds, with a scaffold N50 of 20 356 bp. We demonstrate how recent improvements in the sequencing technology, especially increasing read lengths and paired end reads from longer fragments have a major impact on the assembly contiguity. We also note that scalable bioinformatics tools are instrumental in providing rapid draft assemblies. Availability: The Picea glauca genome sequencing and assembly data are available through NCBI (Accession#: ALWZ0100000000 PID: PRJNA83435). http://www.ncbi.nlm.nih.gov/bioproject/83435 .

    Organellar Genomes of White Spruce (Picea glauca): Assembly and Annotation (2016)
    Oxford University Press
    Details
    Publication Date: 2016-01-08
    Description: The genome sequences of the plastid and mitochondrion of white spruce ( Picea glauca ) were assembled from whole-genome shotgun sequencing data using ABySS. The sequencing data contained reads from both the nuclear and organellar genomes, and reads of the organellar genomes were abundant in the data as each cell harbors hundreds of mitochondria and plastids. Hence, assembly of the 123-kb plastid and 5.9-Mb mitochondrial genomes were accomplished by analyzing data sets primarily representing low coverage of the nuclear genome. The assembled organellar genomes were annotated for their coding genes, ribosomal RNA, and transfer RNA. Transcript abundances of the mitochondrial genes were quantified in three developmental tissues and five mature tissues using data from RNA-seq experiments. C-to-U RNA editing was observed in the majority of mitochondrial genes, and in four genes, editing events were noted to modify ACG codons to create cryptic AUG start codons. The informatics methodology presented in this study should prove useful to assemble organellar genomes of other plant species using whole-genome shotgun sequencing data.

    Description: Author(s): S. J. Jones and H. M. Wiseman A single-photon incident on a beam splitter produces an entangled field state, and in principle could be used to violate a Bell inequality, but such an experiment (without postselection) is beyond the reach of current experiments. Here we consider the somewhat simpler task of demonstrating Einstein-... [Phys. Rev. A 84, 012110] Published Tue Jul 12, 2011

    Structure/function study of AvrRps4 immunity [Plant Biology] (2012)
    National Academy of Sciences
    Details
    Publication Date: 2012-10-03
    Description: Gram-negative phytopathogenic bacteria translocate effector proteins into plant cells to subvert host defenses. These effectors can be recognized by plant nucleotide-binding–leucine-rich repeat immune receptors, triggering defense responses that restrict pathogen growth. AvrRps4, an effector protein from Pseudomonas syringae pv. pisi, triggers RPS4-dependent immunity in resistant accessions of Arabidopsis. To better...

    BreakFusion: targeted assembly-based identification of gene fusions in whole transcriptome paired-end sequencing data (2012)
    Oxford University Press
    Details
    Publication Date: 2012-07-06
    Description: : Despite recent progress, computational tools that identify gene fusions from next-generation whole transcriptome sequencing data are often limited in accuracy and scalability. Here, we present a software package, BreakFusion that combines the strength of reference alignment followed by read-pair analysis and de novo assembly to achieve a good balance in sensitivity, specificity and computational efficiency.

    Cultivation can increase harvesting pressure on overexploited plant populations (2014)
    Wiley
    Details
    Publication Date: 2014-12-01
    Description: Captive breeding and cultivation of overharvested species is frequently proposed as a conservation strategy, yet there is little evidence under what conditions, if at all, the strategy is effective. We created a bioeconomic model to investigate the socioeconomic conditions favoring cultivation over wild harvesting and likely impacts on the wild population. We parameterize the model with the case study of illegal xaté palm (Chamaedorea ernesti-augusti) harvesting in Belize and Guatemala. We examine how changes in law enforcement, a price premium for cultivated leaf, land ownership, and alternative income might affect decisions to cultivate and the impact of cultivation on wild populations. We show that those switching to cultivation are largely not wild harvesters because of barriers such as land ownership. We also find that if harvesters do switch to cultivation, they may have a negative effect on the wild population through harvesting of material to set up plantations. We found increasing alternative income reduces harvesting pressure and suggests the provision of alternative livelihoods would more directly reduce pressure on the wild population. Although schemes to encourage cultivation seem an appealing conservation intervention, we urge caution in assuming that people will readily adopt cultivation of wild harvested species or that this would necessarily reduce impacts on wild populations. # doi:10.1890/13-2264.1

    Nonmethylated transposable elements and methylated genes in a chordate genome (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-02-19
    Description: The genome of the invertebrate chordate Ciona intestinalis was found to be a stable mosaic of methylated and nonmethylated domains. Multiple copies of an apparently active long terminal repeat retrotransposon and a long interspersed element are nonmethylated and a large fraction of abundant short interspersed elements are also methylation free. Genes, by contrast, are predominantly methylated. These data are incompatible with the genome defense model, which proposes that DNA methylation in animals is primarily targeted to endogenous transposable elements. Cytosine methylation in this urochordate may be preferentially directed to genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simmen, M W -- Leitgeb, S -- Charlton, J -- Jones, S J -- Harris, B R -- Clark, V H -- Bird, A -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1999 Feb 19;283(5405):1164-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Cell and Molecular Biology, University of Edinburgh, The King's Buildings, Edinburgh EH9 3JR, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10024242" target="_blank"〉PubMed〈/a〉

    Comparative genomics of the eukaryotes (2000)

    Publication Date: 2000-03-24
    Description: A comparative analysis of the genomes of Drosophila melanogaster, Caenorhabditis elegans, and Saccharomyces cerevisiae-and the proteins they are predicted to encode-was undertaken in the context of cellular, developmental, and evolutionary processes. The nonredundant protein sets of flies and worms are similar in size and are only twice that of yeast, but different gene families are expanded in each genome, and the multidomain proteins and signaling pathways of the fly and worm are far more complex than those of yeast. The fly has orthologs to 177 of the 289 human disease genes examined and provides the foundation for rapid analysis of some of the basic processes involved in human disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2754258/" 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/PMC2754258/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rubin, G M -- Yandell, M D -- Wortman, J R -- Gabor Miklos, G L -- Nelson, C R -- Hariharan, I K -- Fortini, M E -- Li, P W -- Apweiler, R -- Fleischmann, W -- Cherry, J M -- Henikoff, S -- Skupski, M P -- Misra, S -- Ashburner, M -- Birney, E -- Boguski, M S -- Brody, T -- Brokstein, P -- Celniker, S E -- Chervitz, S A -- Coates, D -- Cravchik, A -- Gabrielian, A -- Galle, R F -- Gelbart, W M -- George, R A -- Goldstein, L S -- Gong, F -- Guan, P -- Harris, N L -- Hay, B A -- Hoskins, R A -- Li, J -- Li, Z -- Hynes, R O -- Jones, S J -- Kuehl, P M -- Lemaitre, B -- Littleton, J T -- Morrison, D K -- Mungall, C -- O'Farrell, P H -- Pickeral, O K -- Shue, C -- Vosshall, L B -- Zhang, J -- Zhao, Q -- Zheng, X H -- Lewis, S -- P4IHG00739/HG/NHGRI NIH HHS/ -- P50HG00750/HG/NHGRI NIH HHS/ -- R01 GM037193/GM/NIGMS NIH HHS/ -- R01 GM037193-14/GM/NIGMS NIH HHS/ -- R01 GM037193-15/GM/NIGMS NIH HHS/ -- R01 GM060988/GM/NIGMS NIH HHS/ -- R01 GM060988-01/GM/NIGMS NIH HHS/ -- R01 NS040296/NS/NINDS NIH HHS/ -- R01 NS040296-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2000 Mar 24;287(5461):2204-15.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular and Cell Biology, Berkeley Drosophila Genome Project, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10731134" target="_blank"〉PubMed〈/a〉

    The Genome sequence of the SARS-associated coronavirus (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-06
    Description: We sequenced the 29,751-base genome of the severe acute respiratory syndrome (SARS)-associated coronavirus known as the Tor2 isolate. The genome sequence reveals that this coronavirus is only moderately related to other known coronaviruses, including two human coronaviruses, HCoV-OC43 and HCoV-229E. Phylogenetic analysis of the predicted viral proteins indicates that the virus does not closely resemble any of the three previously known groups of coronaviruses. The genome sequence will aid in the diagnosis of SARS virus infection in humans and potential animal hosts (using polymerase chain reaction and immunological tests), in the development of antivirals (including neutralizing antibodies), and in the identification of putative epitopes for vaccine development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marra, Marco A -- Jones, Steven J M -- Astell, Caroline R -- Holt, Robert A -- Brooks-Wilson, Angela -- Butterfield, Yaron S N -- Khattra, Jaswinder -- Asano, Jennifer K -- Barber, Sarah A -- Chan, Susanna Y -- Cloutier, Alison -- Coughlin, Shaun M -- Freeman, Doug -- Girn, Noreen -- Griffith, Obi L -- Leach, Stephen R -- Mayo, Michael -- McDonald, Helen -- Montgomery, Stephen B -- Pandoh, Pawan K -- Petrescu, Anca S -- Robertson, A Gordon -- Schein, Jacqueline E -- Siddiqui, Asim -- Smailus, Duane E -- Stott, Jeff M -- Yang, George S -- Plummer, Francis -- Andonov, Anton -- Artsob, Harvey -- Bastien, Nathalie -- Bernard, Kathy -- Booth, Timothy F -- Bowness, Donnie -- Czub, Martin -- Drebot, Michael -- Fernando, Lisa -- Flick, Ramon -- Garbutt, Michael -- Gray, Michael -- Grolla, Allen -- Jones, Steven -- Feldmann, Heinz -- Meyers, Adrienne -- Kabani, Amin -- Li, Yan -- Normand, Susan -- Stroher, Ute -- Tipples, Graham A -- Tyler, Shaun -- Vogrig, Robert -- Ward, Diane -- Watson, Brynn -- Brunham, Robert C -- Krajden, Mel -- Petric, Martin -- Skowronski, Danuta M -- Upton, Chris -- Roper, Rachel L -- New York, N.Y. -- Science. 2003 May 30;300(5624):1399-404.
