SILVA

Welcome to the SILVA rRNA database project

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.

SILVA Alignment, Classification and Tree (ACT) Service

 

The SILVA ACT service combines alignment, search and classify as well as reconstruction of trees in a single web application.

SILVA ACT is available at: Opens internal link in current windowwww.arb-silva.de/act

SILVA Tree Viewer

 

The SILVA Tree Viewer is a web application to browse and query the SILVA guide trees.

A technical preview is available at Opens external link in new windowwww.arb-silva.de/treeviewer.

ARB

 

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 almost 30 years ago by Wolfgang Ludwig at the Technical University in Munich, Germany, see Opens external link in new windowwww.arb-home.de.

UniEuk

 

SILVA is a member of the Opens external link in new windowUniEuk 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.
