Query: NC_015914:2230076 Cyclobacterium marinum DSM 745 chromosome, complete genome Lineage: Cyclobacterium marinum; Cyclobacterium; Cyclobacteriaceae; Cytophagales; Bacteroidetes; Bacteria General Information: Isolation: Coelomic fluid of a sand dollar; Temp: Mesophile. Gram-negative bacterium isolated from coelomic fluid of a sand dollarfish (Poronotus triacanthus) of the family Stromateidae (butterfish family), a family of fishes with almost circular bodies and small mouths. The dollarfish (genus Peprilus), is found from Maine to South Carolina, USA during the summer.

General Information: This biovar nodulates legumes in the Tribe Viciae (Vicia, Pisum, Lathyrus, Lens). This strain is a spontaneous streptomycin-resistant mutant of strain 300. Nitrogen-fixing plant symbiont. This organism, like other Rhizobia, establishes a symbiotic relationship with a legume plant, providing nitrogen in exchange for a protected environment. The legume roots secrete flavonoids and isoflavonoids which the bacteria recognize and use to turn on genes involved in root nodulation. Many of the root nodulation genes are involved in synthesis and secretion of a nodule inducing signal, a lipochito-oligosaccharide molecule, which the plant recognizes, triggering nodule formation. The bacterium is endocytosed and exists inside a membrane bound organelle, the symbiosome, and fixes nitrogen for the plant cell while the host cell provides carbon compounds for the bacterium to grow on. The nitrogen fixation is important as it obviates the need for expensive and environmentally damaging fertilizer use.
