Query: NC_008380:4078670 Rhizobium leguminosarum bv. viciae 3841, complete genome

Lineage: Rhizobium leguminosarum; Rhizobium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria

General Information: This biovar nodulates legumes in the Tribe Viciae (Vicia, Pisum, Lathyrus, Lens). This strain is a spontaneous streptomycin-resistant mutant of strain 300. Nitrogen-fixing plant symbiont. This organism, like other Rhizobia, establishes a symbiotic relationship with a legume plant, providing nitrogen in exchange for a protected environment. The legume roots secrete flavonoids and isoflavonoids which the bacteria recognize and use to turn on genes involved in root nodulation. Many of the root nodulation genes are involved in synthesis and secretion of a nodule inducing signal, a lipochito-oligosaccharide molecule, which the plant recognizes, triggering nodule formation. The bacterium is endocytosed and exists inside a membrane bound organelle, the symbiosome, and fixes nitrogen for the plant cell while the host cell provides carbon compounds for the bacterium to grow on. The nitrogen fixation is important as it obviates the need for expensive and environmentally damaging fertilizer use.

Subject: NC_007716:266500 Aster yellows witches'-broom phytoplasma AYWB, complete genome

Lineage: Aster yellows witches'-broom phytoplasma; Phytoplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria

General Information: Mycoplasma-like plant pathogen. Aster yellows witches'-broom phytoplasma belongs to a group of mycoplasma-like organisms that infect plants and insects. Phytoplasmas are insect-transmitted plant pathogens that cause economically important diseases in many plant species, including vegetables, ornamentals, and fruit crops. Aster yellows is a sporadic disease of vegetable crops and is transmitted by the aster leafhopper.
