Query: NC_017326:1122103 Sinorhizobium meliloti SM11 plasmid pSmeSM11d, complete sequence
Lineage: Sinorhizobium meliloti; Sinorhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This organism, much like other Rhizobia, forms a symbiotic relationship with a leguminous plant, in this case the alfalfa plant (Medicago sativa). Expression of nodulation genes results in production of a nodulation signal which the plant cell recognizes inducing root nodule formation. The plant cell provides carbon compounds for the bacterium to grow on.
Subject: 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.
