Complete Genome Sequence of Roseibium sp. Strain Sym1, a Bacterial Associate of Symbiodinium linucheae, the Microalgal Symbiont of the Anemone Aiptasia

We sequenced the genome of Roseibium sp. strain Sym1, a strain isolated from a monoculture of a Symbiodiniaceae marine dinoflagellate, Symbiodinium linucheae, a microalgal symbiont of cnidarians. The completed genome consists of one circular chromosome of 6,694,563 bp and four plasmids of 192,102 bp, 160,136 bp, 120,881 bp, and 89,413 bp.
