Show abstract

We present an update to the PIGEON (Phages and Integrated Genomes Encapsidated or Not) reference database of DNA viral sequences (vOTUs, mostly dsDNA bacteriophages) from global ecosystems. To reflect the inclusion of only virus size-fractionated metagenome- (virome-)derived vOTUs, we reintroduce the database as PEONY (Phages Encapsidated ONlY) and present new data summarizing the utility of this database.
