Key Points

Pseudovibrio ascidiaceicola has a complete genomic assembly of 6.94 Mb, indicating significant genetic features.
The bacterium houses 22 contigs and 6,613 protein-coding genes, highlighting its complex genetic makeup.
Prophage regions are present, revealing possible mechanisms for horizontal gene transfer within this bacterial symbiont.
Isolated from Ciona robusta, this strain underscores the unique symbiotic relationships in marine ecosystems.

Implication

Isolation of Pseudovibrio ascidiaceicola from Ciona robusta gut reveals unique genomic structures, suggesting evolutionary adaptations.

Abstract

We isolated Pseudovibrio ascidiaceicola strain 5337, a gut bacterium of the ascidian Ciona robusta, from Mission Bay, San Diego. The genomic assembly is 6.94 Mb and 99.99% complete, comprising 22 contigs and 6,613 protein-coding genes. Unicycler identified seven circular contigs, and PHASTEST identified 11 prophage regions, including two gene transfer agents.
