Query: NC_007205:499808 Candidatus Pelagibacter ubique HTCC1062, complete genome
Lineage: Pelagibacter ubique; Pelagibacter; Pelagibacteraceae; Rickettsiales; Proteobacteria; Bacteria
General Information: They were originally named SAR11 and known only from their rRNA genes, which were first identified in environmental samples from the Sargasso Sea in 1990. P. ubique are possibly the most numerous bacteria in the world.
Subject: NC_007712:2806500 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.
