Welcome
to the Plasmid Genome Database
The Plasmid Genome Database
aims to collate biological and genomic data for all bacterial
plasmids in the hope of enabling rapid, interrogation of
both meta- and genomic data. Data maintained includes access
to all plasmid genomes and information on core genomic features
obtained from parsing the original EMBL/DDBJ/NCBI submission. In addition a suite of third party analyses has been performed for each genome to supplement the original annotation. This site also links to Genome Atlases provided by the Centre for Biological Sequence Analysis (CBS).
The motivation behind
the construction of this site derived from observations from
genome sequencing projects: the abundance and inferred importance
of the horizontal gene pool (HGP) in bacterial adaptation
and evolution. In so far as plasmids are autonomously replicating,
extrachromosomal elements they are a readily identifiable
and accessible component of the HGP. Also plasmids have been
identified in almost all bacterial divisions, ranging in size
from less than 2 kbp to > 1.5 Mbp and as such represent
a defined, yet diverse and complex sample of genes in the
HGP.
