Query: NC_017249:18493 Bradyrhizobium japonicum USDA 6, complete genome

Lineage: Bradyrhizobium japonicum; Bradyrhizobium; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This nitrogen-fixing bacterium develops a symbiotic relationship with the soybean plant Glycine max and is related to other N2-fixing Rhizobia which are symbiotic with legumes. The bacterium establishes itself in a root nodule which provides a protective environment for the organism to live while the bacterium provides the plant cell with nitrogen. This is an agriculturally important symbiotic relationship as it obviates the need for expensive and environmentally damaging fertilizer.Genes that code for proteins involved in root nodulation are carried on the chromosome. The production of the nodulation signal, lipochitin, is directed by genes which are turned on in the presence of plant flavonoid compounds. The bacteria are endocytosed into a cortical cell, and are enclosed within a membrane bound organelle termed the symbiosome.

Subject: NC_011982:130199 Agrobacterium vitis S4 plasmid pTiS4, complete sequence

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.
