Query: NC_009937:958576 Azorhizobium caulinodans ORS 571, complete genome
Lineage: Azorhizobium caulinodans; Azorhizobium; Xanthobacteraceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This species is a stem-nodulating nitrogen-fixing organism isolated from Sesbania rostrata. Azorhizobium caulinodans ORS571 is a microsymbiont of the water-tolerant tropical legume Sesbania rostrata.A. caulinodans ORS571 is able to fix nitrogen in the free-living state, which is not the case for most rhizobia.
Subject: NC_010162:573709 Sorangium cellulosum 'So ce 56', complete genome
Lineage: Sorangium cellulosum; Sorangium; Polyangiaceae; Myxococcales; Proteobacteria; Bacteria
General Information: Sorangium cellulosum 'So ce 56' produces a large number of bioactive compounds, such as, the antifungal soraphen and the anticancer agent epothilone. This organism, like other myxobacteria, undergoes a complex development and differentiation pathway. When cell density increases, the organism switches to "social motility" where aggregates of cells can gather together into masses termed fruiting bodies that may consist of up to 100 000 cells. The motility system is not dependent on flagella like most bacteria, but instead relies on twitching pili: short extracellular appendages that may function analogously to oars in a rowboat. The myxobacteria have proved to be a rich source of novel natural products. Sorangium cellulosum produces a number of antibacterial, antifungal and cytotoxic substances which are being studies for therapeutic applications.
