Query: NC_007761:3564449 Rhizobium etli CFN 42, complete genome
Lineage: Rhizobium etli; Rhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: It is a nitrogen-fixing symbiotic bacteria that interacts with the root of the common bean plant Phaseolus vulgaris. P. etli and its relation to other nitrogen/fixing symbionts has been well studied. The genomic sequence will provide information on the process of symbiosis, on the genetic systems that allow the survival and adaptations of this bacteria to the soil, and on the evolutionary relationship and the symbiosis origin of this organism.
Subject: NC_015957:10505870 Streptomyces violaceusniger Tu 4113 chromosome, complete genome
Lineage: Streptomyces violaceusniger; Streptomyces; Streptomycetaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Environment: Soil, Terrestrial; Temp: Mesophile. Streptomyces violaceusniger 16S rRNA gene clade form a gray aerial spore mass and a grayish-yellow substrate mycelium on oatmeal agar, and produce aerial hyphae that differentiate into spiral chains of rugose ornamented spores. The characteristic earthy smell of freshly plowed soil is actually attributed to the aromatic terpenoid geosmin produced by species of Streptomyces. There are currently 364 known species of this genus, many of which are the most important industrial producers of antibiotics and other secondary metabolites of antibacterial, antifungal, antiviral, and antitumor nature, as well as immunosuppressants, antihypercholesterolemics, etc. Streptomycetes are crucial in the soil environment because their diverse metabolism allows them to degrade the insoluble remains of other organisms, including recalcitrant compounds such as lignocelluloses and chitin.
