Query: NC_014248:685656 Nostoc azollae 0708 chromosome, complete genome
Lineage: Trichormus azollae; Trichormus; Nostocaceae; Nostocales; Cyanobacteria; Bacteria
General Information: Isolation: water fern Azolla; Temp: Mesophile; Habitat: Host. Nostoc azollae, formerly Anabaena azollae, is a cyanobacterial symbiont of the water fern Azolla, commonly known as 'duckweed'. Nostoc azollae is a nitrogen-fixer and provides nitrogen to the host plant.
Subject: NC_011653:1226035 Thermosipho africanus TCF52B, complete genome
Lineage: Thermosipho africanus; Thermosipho; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: This organism was isolated from the Troll oil formation in the North Sea. Thermosipho africanus, a member of the Thermotogales, has the characteristic morphology of one or more cells contained in a sheath-like envelope which extends beyond the cell wall. Preliminary sequencing of Thermotogales genomes has identified extensive horizontal gene transfer between these organisms and the Archaea. Thermosipho africanus has been isolated from marine hydrothermal systems and oil reservoir production waters.
