PLAZA 3.0 is designed to make comparative genomics data for plants available through a user-friendly web interface. Structural and functional annotation, gene families, protein domains, phylogenetic trees and detailed information about genome organization can easily be queried and visualized. Compared with the first version released in 2009, which featured nine organisms, the number of integrated genomes is more than four times higher, and now covers 37 plant species. The new species provide a wider phylogenetic range as well as a more in-depth sampling of specific clades, and genomes of additional crop species are present. The functional annotation has been expanded and now comprises data from Gene Ontology, MapMan, UniProtKB/Swiss-Prot, PlnTFDB and PlantTFDB. Furthermore, we improved the algorithms to transfer functional annotation from well-characterized plant genomes to other species. The additional data and new features make PLAZA 3.0 (http://bioinformatics.psb.ugent.be/plaza/) a versatile and comprehensible resource for users wanting to explore genome information to study different aspects of plant biology, both in model and non-model organisms.}, language = {en} } @article{ReadKegelKluteetal.2013, author = {Read, Betsy A. and Kegel, Jessica and Klute, Mary J. and Kuo, Alan and Lefebvre, Stephane C. and Maumus, Florian and Mayer, Christoph and Miller, John and Monier, Adam and Salamov, Asaf and Young, Jeremy and Aguilar, Maria and Claverie, Jean-Michel and Frickenhaus, Stephan and Gonzalez, Karina and Herman, Emily K. and Lin, Yao-Cheng and Napier, Johnathan and Ogata, Hiroyuki and Sarno, Analissa F. and Shmutz, Jeremy and Schroeder, Declan and de Vargas, Colomban and Verret, Frederic and von Dassow, Peter and Valentin, Klaus and Van de Peer, Yves and Wheeler, Glen and Dacks, Joel B. and Delwiche, Charles F. and Dyhrman, Sonya T. and Gl{\"o}ckner, Gernot and John, Uwe and Richards, Thomas and Worden, Alexandra Z. and Zhang, Xiaoyu and Grigoriev, Igor V. and Allen, Andrew E. and Bidle, Kay and Borodovsky, M. and Bowler, C. and Brownlee, Colin and Cock, J.

These marine phytoplankton can account for 20 per cent of total carbon fixation in some systems(2). They form blooms that can occupy hundreds of thousands of square kilometres and are distinguished by their elegantly sculpted calcium carbonate exoskeletons (coccoliths), rendering them visible from space(3). Although coccolithophores export carbon in the form of organic matter and calcite to the sea floor, they also release CO2 in the calcification process. Hence, they have a complex influence on the carbon cycle, driving either CO2 production or uptake, sequestration and export to the deep ocean(4). Here we report the first haptophyte reference genome, from the coccolithophore Emiliania huxleyi strain CCMP1516, and sequences from 13 additional isolates. Our analyses reveal a pan genome (core genes plus genes distributed variably between strains) probably supported by an atypical complement of repetitive sequence in the genome. Comparisons across strains demonstrate that E. huxleyi, which has long been considered a single species, harbours extensive genome variability reflected in different metabolic repertoires. Genome variability within this species complex seems to underpin its capacity both to thrive in habitats ranging from the equator to the subarctic and to form large-scale episodic blooms under a wide variety of environmental conditions.}, language = {en} } @article{RuprechtLohausVannesteetal.2017, author = {Ruprecht, Colin and Lohaus, Rolf and Vanneste, Kevin and Mutwil, Marek and Nikoloski, Zoran and Van de Peer, Yves and Persson, Staffan}, title = {Revisiting ancestral polyploidy in plants}, series = {Science Advances}, volume = {3}, journal = {Science Advances}, publisher = {American Assoc. for the Advancement of Science}, address = {Washington}, issn = {2375-2548}, doi = {10.1126/sciadv.1603195}, pages = {6}, year = {2017}, abstract = {Whole-genome duplications (WGDs) or polyploidy events have been studied extensively in plants. In a now widely cited paper, Jiao et al. presented evidence for two ancient, ancestral plant WGDs predating the origin of flowering and seed plants, respectively. This finding was based primarily on a bimodal age distribution of gene duplication events obtained from molecular dating of almost 800 phylogenetic gene trees. We reanalyzed the phylogenomic data of Jiao et al. and found that the strong bimodality of the age distribution may be the result of technical and methodological issues and may hence not be a "true" signal of two WGD events. By using a state-of-the-art molecular dating algorithm, we demonstrate that the reported bimodal age distribution is not robust and should be interpreted with caution. Thus, there exists little evidence for two ancient WGDs in plants from phylogenomic dating.}, language = {en} } @misc{VanBelProostVanNesteetal.2013, author = {Van Bel, Michiel and Proost, Sebastian and Van Neste, Christophe and Deforce, Dieter and Van de Peer, Yves and Vandepoele, Klaas}, title = {TRAPID}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {900}, issn = {1866-8372}, doi = {10.25932/publishup-43640}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-436409}, pages = {12}, year = {2013}, abstract = {Transcriptome analysis through next-generation sequencing technologies allows the generation of detailed gene catalogs for non-model species, at the cost of new challenges with regards to computational requirements and bioinformatics expertise.
