Query: NC_008702:3928043 Azoarcus sp. BH72, complete genome
Lineage: Azoarcus; Azoarcus; Rhodocyclaceae; Rhodocyclales; Proteobacteria; Bacteria
General Information: This organism is a nitrogen-fixing obligate endophyte first isolated from the roots of Kaller grass in the Punjab region of Pakistan. These organisms are never found in root-free soil and colonize root tissues without causing disease. This strain has been shown to express genes involved in nitrogen fixation in root tissue and is thought to provide significant amounts of nitrogen to its host plant.
Subject: NC_009767:4755000 Roseiflexus castenholzii DSM 13941, complete genome
Lineage: Roseiflexus castenholzii; Roseiflexus; Chloroflexaceae; Chloroflexales; Chloroflexi; Bacteria
General Information: Photosynthetic thermophile. Roseiflexus castenholzii is related to the Chloroflexaceae, a family of anoxygenic phototrophs. However, it differs from other members of that family in that it lacks chlorosomes and bacteriochlorophyll-c. Bacteriochlorophyll-a is the major photosynthetic pigment in Roseiflexus castenholzii. This organism was isolated from a hot spring microbial mat in a Japanese hot spring.
