The settlement and metamorphosis of coral larvae are the bottleneck of coral recruitment. They are critical for the extension of coral population, which is the basis of the restoration of degraded coral reef ecosystem. In this study, we described the genomic characteristics of Metabacillus sp. cB07, which can efficiently induce larvae settlement and metamorphosis of coral Pocillopora damicornis. This function is first reported in the genus Metabacillus. Strain cB07 was isolated from the coral Porites pukoensis, and comprised one circular chromosome of 4,148,576 bp (44.14 mol% G + C content), containing 4148 protein coding sequences. To explore the potential mechanism of coral larvae settlement and metamorphosis induced by Metabacillus sp. cB07, we predicted that numerous genes related to the bacterial inductive ability. The genome of Metabacillus sp. cB07 will be helpful for further insights into the mechanism of bacterial induction of settlement and metamorphosis of coral larvae.
