Query: NC_005061:96536 Candidatus Blochmannia floridanus, complete genome
Lineage: Blochmannia floridanus; Blochmannia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Ant endosymbiont. This organism is an endosymbiont that is associated with carpenter ants. It is related to other endosymbionts like Buchnera and Wigglesworthia. Within the ant host, the bacteria live within specialized cells called bacteriocytes in the midgut and ovaries.
Subject: NC_008312:5357567 Trichodesmium erythraeum IMS101, complete genome
Lineage: Trichodesmium erythraeum; Trichodesmium; ; Oscillatoriales; Cyanobacteria; Bacteria
General Information: Trichodesmium erythraeum strain IMS101 was isolated from the North Carolina coast in 1992 and grows in straight filaments. Filamentous marine cyanobacterium. This filamentous marine cyanobacterium is a nitrogen-fixing organism that contribues a significant amount of the global fixed nitrogen each year. These bacteria are unusual in that nitrogen fixation takes place in a differentiated cell called the diazocyte which is different from the nitrogen-fixing differentiated cell (heterocyst) found in other cyanobacteria. The diazocyte is developed in order to protect the oxygen-sensitive nitrogenases and includes a number of changes including production of more membranes and down-regulation of photosynthetic activity during times of peak nitrogen fixation (noontime). This organism gives the Red Sea its name when large blooms appear and is one of the organisms most often associated with large blooms in marine waters.
