Query: NC_009445:7220929 Bradyrhizobium sp. ORS 278 chromosome, complete genome

Lineage: Bradyrhizobium; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This strain was isolated from an Aeschynomene stem nodule and is photosynthetic, which is a rare trait in Rhizobium bacteria. These strains exhibit a photoheterotrophic and strictly aerobic photosynthesis. In culture, most stem isolates show the same pink coloration, while a few strains produce orange pigmentation. Pigment analyses showed that bacteriochlorophyll and spirilloxanthin, two pigments of the light harvesting system, are common to all of these photosynthetic Bradyrhizobium strains, whereas orange strains produce an additional bicyclic carotenoid, canthaxanthin (4,4'-diketo-beta-carotene). Bradyrhizobium sp. strain ORS278 produces the highest quantity of canthaxanthin of all tested photosynthetic bacteria; canthaxanthin represents 85% of its total carotenoid content.

Subject: NC_008542:2631138 Burkholderia cenocepacia HI2424 chromosome 1, complete sequence

Lineage: Burkholderia cenocepacia; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria

General Information: This organism (HI2424; BCC1) was isolated as part of a study to find this organism in natural environments. Samples taken from fields that were planted with onions in New York in 1999 and 2000 were examined and it was discovered that isolates were the same as ones that can infect CF patients. This species (genomovar III) is part of the Burkholderia cepacia complex, which consists of 9 closely related species, also known as genomovars. These organisms are commonly found in soil and all are opportunistic pathogens espcially in cystic fibrosis patients.
