Rhizobium leguminosarum is a widely studied alpha-proteobacterial N2-fixing legume symbiont of legumes. It has three biovars - viciae, trifolii, phaseoli - that differ in their host specificity. Biovar viciae (sequenced here) nodulates legumes in the Tribe Viciae - Vicia, Pisum, Lathyrus, Lens. The host-specificity genes are carried on large plasmids that also carry the genes for nitrogen fixation. R. leguminosarum biovar viciae strain 3841 has been widely used in laboratory studies over the past 20 years. It is a spontaneous streptomycin-resistant mutant of strain 300. It has a circular chromosome and 6 circular plasmids, ranging in size from approximately 140 to 870 kb. One of these plasmids (pRL10) carries the genes for nodulation and nitrogen fixation, but the function of the great majority of the plasmid-borne genes is unknown at present. All strains of R. leguminosarum have several large plasmids, but the number and sizes of plasmids varies among strains. This large number of plasmids distinguishes R. leguminosarum from the other rhizobia for which complete genome sequences have been determined.
