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

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.

Genomic conservation and putative downstream functionality of the phosphatidylinositol signalling pathway in the cnidarian-dinoflagellate symbiosis

The mutualistic cnidarian-dinoflagellate symbiosis underpins the evolutionary success of stony corals and the persistence of coral reefs. However, a molecular understanding of the signalling events that lead to the successful establishment and maintenance of this symbiosis remains unresolved. For example, the phosphatidylinositol (PI) signalling pathway has been implicated during the establishment of multiple mutualistic and parasitic interactions across the kingdoms of life, yet its role within…
