Query: NC_003047:2798367 Sinorhizobium meliloti 1021, complete genome
Lineage: Sinorhizobium meliloti; Sinorhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Streptomycin resistant derivative of strain 2011. Plant symbiotic bacterium. 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_011988:1036618 Agrobacterium vitis S4 chromosome 2, complete genome
Lineage: Agrobacterium vitis; Agrobacterium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Agrobacterium vitis is the causative agent of crown gall disease in grapes. Agrobacterium are Gram-negative, motile, soil-dwelling plant pathogens with the species name given based on the disease phenotype associated with the bacteria. Disease causing Agrobacterium spp. possess a tumor-inducing (Ti) plasmid, which carries genes for the formation of opines. A segment of the Ti plasmid gets transferred to the plant cell and integrates into the host cell genome. The plant cell then starts synthesizing opines, which can be catabolized by Agrobacterium spp, but not by the plant cells.
