Query: NC_007761:781210 Rhizobium etli CFN 42, complete genome
Lineage: Rhizobium etli; Rhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: It is a nitrogen-fixing symbiotic bacteria that interacts with the root of the common bean plant Phaseolus vulgaris. P. etli and its relation to other nitrogen/fixing symbionts has been well studied. The genomic sequence will provide information on the process of symbiosis, on the genetic systems that allow the survival and adaptations of this bacteria to the soil, and on the evolutionary relationship and the symbiosis origin of this organism.
Subject: NC_011060:514874 Pelodictyon phaeoclathratiforme BU-1, complete genome
Lineage: Pelodictyon phaeoclathratiforme; Pelodictyon; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: Pelodictyon phaeoclathratiformeBU-1 was isolated from lake water in 1989. This organism is a phototrophic green sulfur bacteria that inhabits hydrogen sulfide-containing water and freshwater mud, brackish waters and marine environments. This organism forms net-like microcolonies and contains gas vescicles. It is believed that the gas vesicles provide the buoyancy necessary to keep the cell at the optimal depth for photosynthesis.
