Journal ArticleDOI
Genome-Based Taxonomic Classification of Bacteroidetes.
Richard L. Hahnke,Jan P. Meier-Kolthoff,Marina García-López,Supratim Mukherjee,Marcel Huntemann,Natalia Ivanova,Tanja Woyke,Nikos C. Kyrpides,Hans-Peter Klenk,Markus Göker +9 more
TL;DR: A large collection of type-strain genomes from Bacteroidetes and closely related phyla are assessed based on the principles of phylogenetic classification and trees inferred from genome-scale data and corrected G+C content values have a significantly better fit to the phylogeny.
Journal ArticleDOI
IMG/VR: a database of cultured and uncultured DNA Viruses and retroviruses.

TL;DR: IMG/VR is presented, the largest publicly available database of 3908 isolate reference DNA viruses with 264 413 computationally identified viral contigs from >6000 ecologically diverse metagenomic samples, serving as an essential resource in the viral genomics community.
Journal ArticleDOI
Comparative metagenomic and metatranscriptomic analysis of hindgut paunch microbiota in wood- and dung-feeding higher termites
Shaomei He,Natalia Ivanova,Natalia Ivanova,Edward Kirton,Martin Allgaier,Martin Allgaier,Claudia Bergin,Rudolf H. Scheffrahn,Nikos C. Kyrpides,Nikos C. Kyrpides,Falk Warnecke,Falk Warnecke,Susannah G. Tringe,Philip Hugenholtz,Philip Hugenholtz,Philip Hugenholtz +15 more
TL;DR: A convergence was observed for functions essential to termite biology including hydrolytic enzymes, homoacetogenesis and cell motility and chemotaxis and may also reflect the phylogenetic difference between the hosts.
Journal ArticleDOI
IMG/VR v.2.0: an integrated data management and analysis system for cultivated and environmental viral genomes.
David Paez-Espino,Simon Roux,I-Min A. Chen,Krishna Palaniappan,Anna Ratner,Ken Chu,Marcel Huntemann,T. B. K. Reddy,Joan Carles Pons,Mercè Llabrés,Emiley A. Eloe-Fadrosh,Natalia Ivanova,Nikos C. Kyrpides +12 more
TL;DR: To improve data quality and predictions of host specificity, IMG/VR v.2.0 now separates prokaryotic and eukaryotic viruses, utilizes known prophage sequences to improve taxonomic assignments, and provides viral genome quality scores based on the estimated genome completeness.
Journal ArticleDOI
Millimeter-scale genetic gradients and community-level molecular convergence in a hypersaline microbial mat.
Victor Kunin,Jeroen Raes,J. Kirk Harris,John R. Spear,Jeffrey J. Walker,Natalia Ivanova,Christian von Mering,Brad M. Bebout,Norman R. Pace,Peer Bork,Philip Hugenholtz +10 more
TL;DR: All layers of a phylogenetically complex hypersaline mat displayed near‐identical and acid‐shifted isoelectric point profiles due to a molecular convergence of amino‐acid usage, indicating that hypersalinity enforces an overriding selective pressure on the mat community.
