Query: NC_014100:533322 Caulobacter segnis ATCC 21756 chromosome, complete genome
Lineage: Caulobacter segnis; Caulobacter; Caulobacteraceae; Caulobacterales; Proteobacteria; Bacteria
General Information: Isolation: Soil; Temp: Mesophile; Habitat: Fresh water. Caulobacter segnis strain ATCC 21756 is a prostheca-less bacterium belonging to the genus Caulobacter; it was isolated from soil although its habitat is considered to be fresh-water. The absence of a stalk in this genus makes this an interesting bacterium to study.
Subject: NC_008702:1432952 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.
