Query: NC_017249:908500 Bradyrhizobium japonicum USDA 6, complete genome

Lineage: Bradyrhizobium japonicum; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This nitrogen-fixing bacterium develops a symbiotic relationship with the soybean plant Glycine max and is related to other N2-fixing Rhizobia which are symbiotic with legumes. The bacterium establishes itself in a root nodule which provides a protective environment for the organism to live while the bacterium provides the plant cell with nitrogen. This is an agriculturally important symbiotic relationship as it obviates the need for expensive and environmentally damaging fertilizer.Genes that code for proteins involved in root nodulation are carried on the chromosome. The production of the nodulation signal, lipochitin, is directed by genes which are turned on in the presence of plant flavonoid compounds. The bacteria are endocytosed into a cortical cell, and are enclosed within a membrane bound organelle termed the symbiosome.

Subject: NC_007712:4067500 Sodalis glossinidius str. 'morsitans', complete genome

Lineage: Sodalis glossinidius; Sodalis; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: Sodalis glossinidius is known exclusively in endosymbiosis with tsetse flies. It is maternally transmitted, and is one of the few bacterial endosymbionts of insects that can be cultured successfully in vitro. Genome data reveals a high proportion of pseudogenes in this species, many of which were, in their functional state, involved in defense or transport of carbohydrates and inorganic ions. This suggests a degenerative adaptation to the immunity and restricted nutritional status of the host.
