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.

The Quarterly Newsletter Edition March 2017 contains information on two meetings, the 2nd Scientific Advisory Board Meeting and the de.NBI Plenary Meeting both organized last year in Berlin. Furthermore, the newsletter deals with series of interesting topics like interactions with ELIXIR, establishment of the de.NBI cloud and organization of two de.NBI summer schools in 2017. It also contains information on events like the Midterm Review and the de.NBI Symposium.
The new version of the "All Species Living Tree" based on SILVA release 123 for LSU and 128 for SSU has been released.
Many thanks to Tony Walkers for providing us with the QIIME 128 release files.
The SILVA Team wishes you a Merry Christmas and a Happy New Year. Many thanks for your constructive feedback and cooperation to help us improving SILVA and SILVAngs. Looking forward to see you again in 2017.
SILVA is now part of the German Network for Bioinformatics Infrastructure de.NBI.
