Complete genome sequence of Marinobacterium marisflavi strain IMCC4074 isolated from coastal seawater.

OBJECTIVES: Members of the genus Marinobacterium are widely distributed in marine environments and contribute to diverse ecological processes; however, genomic information for several species remains limited. In this study, we report the complete genome sequence of Marinobacterium marisflavi strain IMCC4074ᵀ, originally isolated from coastal seawater of the Yellow Sea, to provide insights into its genomic features, metabolic potential, and environmental adaptation.

DATA DESCRIPTION: The genome of strain IMCC4074ᵀ was sequenced using a combination of short- and long-read sequencing approaches and assembled into a single circular chromosome of 3,091,487 bp with a G + C content of 52.45%. Genome annotation revealed 2,974 protein-coding sequences, 15 rRNA genes, and 60 tRNA genes. Phylogenomic analyses confirmed its taxonomic placement within the genus Marinobacterium, while comparative genomic analysis revealed sufficient divergence (ANI ≤ 95%) from previously described species within the genus, supporting its distinction at the species level and representing the first genome report for this species. The availability of the complete genome provides a resource for understanding the potential ecological roles and adaptive strategies of M. marisflavi in marine ecosystems.
