Azospirillum amazonense Y2 genome sequencing project. Nitrospirillum viridazoti Y2 strain:Y2 (ATCC 35120)

Azospirillumis a well-known genus that embraces bacterial species that can promote plant growth. The A. amazonense species was isolated from forage grasses and plants belonging to the Palmaceae family in Brazil by Magalhães et al. (1983) and subsequent works demonstrated its association with rice, sorghum, maize, sugarcane and Brachiaria, mainly in tropical countries. This species has prominent characteristics when compared to A. brasilense, the most studied species of the genus, as the abilities of fixing nitrogen in the presence of nitrogen (Hartmann, et al., 1986) and being better adapted to acidic soil, the preponderant soil type in Brazil (Magalhães, et al., 1983, Rodrigues, et al., 2008).
