A comprehensive on-line resource for quality checked and aligned ribosomal RNA sequence data.
SILVA provides comprehensive, quality checked and regularly updated datasets of aligned small (16S/18S, SSU) and large subunit (23S/28S, LSU) ribosomal RNA (rRNA) sequences for all three domains of life (Bacteria, Archaea and Eukarya).
SILVA are the official databases of the software package ARB.

The SILVA Tree Viewer is a web application to browse and query the SILVA guide trees.
A technical preview is available at www.arb-silva.de/treeviewer
The software package ARB represents a graphically-oriented, fully-integrated package of cooperating software tools for handling and analysis of sequence information.
The ARB project has been started more than 15 years ago by Wolfgang Ludwig at the Technical University in Munich, Germany, see www.arb-home.de.
SILVA is a member of the UniEuk project, a community-based project to achieve a universal taxonomic framework for Eukaryotes, focused primarily on protists. UniEuk is integrating information from relevant genetic markers and classical morphology-based data, validated by a comprehensive network of taxonomy experts.

Many thanks to the QIIME Team for providing us with the QIIME 132 release files.
Goal: raise awareness for the importance of proper research data management and to provide a practical toolbox for the acquisition, curation, documentation, archiving and publication of research data following the FAIR (Findable, Accessible, Interoperable and Re-usable) data principles. Location: Braunschweig. Deadline for registration: 11 June 2018, but early registration will be a plus.
With the first de.NBI Quarterly Newsletter of the year 2018, it is our pleasure to announce that the second phase of the de.NBI project will start March 2018 and will run for another two years. The first de.NBI Quarterly Newsletter of 2018 informs also on important events of the last three months and announces ma- jor meetings organized by de.NBI and ELIXIR.
SILVAngs has been updated to version 1.7. Improvements: fixed custom fingerprints, fixed layout problems, front page redesigned, added SILVA Twitter feed to front page, new project dashboard, several bugfixes and improvements. The SILVA Team
SILVA is now part of the German Network for Bioinformatics Infrastructure de.NBI.
To evaluate and improve our quality of service we need your feedback. Please help us by participating in this short survey.
