Complete genome sequence of Shewanella marisflavi ECSMB14101, a red pigment synthesizing bacterium isolated from the East China Sea.

Bacteria of the genus Shewanella have been studied for their versatile electron-accepting abilities, particularly for extracellular electron transfer via minerals. Shewanella marisflavi ECSMB14101 was isolated from naturally formed biofilms in the East China Sea. The genome of S.

Deep-sea bacteria trigger settlement and metamorphosis of the mussel Mytilus coruscus larvae.

Bacteria from coast seawaters are widely known to induce larval recruitment of many invertebrates. However, whether and how deep-sea bacteria, that play crucial roles in the ecological and biogeochemical cycles, promote larval recruitment remains little known. Here, the interaction between deep-sea bacterial biofilms (BFs) and Mytilus coruscus larvae was tested.

A bacterial polysaccharide biosynthesis-related gene inversely regulates larval settlement and metamorphosis of .

Larval settlement and metamorphosis is essential for the development of marine invertebrates. Although polysaccharides are involved in larval settlement and metamorphosis of , the molecular basis of polysaccharides underlying this progression remains largely unknown. Here, the roles of the polysaccharide biosynthesis-related gene of ECSMB14103 in the regulation of larval settlement and metamorphosis were examined by gene-knockout technique.
