Subject: NC_002678:2739829 Mesorhizobium loti MAFF303099, complete genome
Lineage: Mesorhizobium loti; Mesorhizobium; Phyllobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Plant symbiont bacterium. This organism contains a symbiosis island that is responsible for symbiotic relationships with plants (lotus) which is similar to what is observed with other Rhizobia that form similar relationships with legumes. The bacterium enters root nodules and performs nitrogen-fixation for the plant cell while being provided with a protective environment to grow in. Nitrogen fixation and root nodule formation genes are carried on a symbiosis island.
