    Full Name of the Resource : rRNA operon numbers in various prokaryotes
    Resource Category : Databases -> Genomic Databases (Non-Human) -> Prokaryotic Genome Databases - General

    Brief Description : The Ribosomal RNA Operon Copy Number Database (rrndb) is an Internet-accessible database, hosted by the Center for Microbial Ecology at Michigan State University, which contains annotated information on rRNA operon copy number among prokaryotes. Gene redundancy is uncommon on prokaryotic genomes, yet the rRNA genes can vary from 1 to as many as 15 copies. Despite the widespread use of 16S rRNA gene sequences for identification of prokaryotes, information on the number and sequence of individual rRNA genes on a genome is not readily accessible. In an attempt to understand the evolutionary and ecological implications of rRNA operon redundancy, we have created a phylogenetically arranged report on rRNA gene copy number for a diverse collection of prokaryotic microorganisms. Each entry (organism) in the rrndb contains detailed information linked directly to external websites including the Ribosomal Database Project, GenBank, PubMed, and several culture collections. Data contained in the rrndb will be valuable to researchers investigating microbial ecology and evolution using rRNA gene sequences.
