AZOSPIRILLUM BRASILENSE
| Class: | Alpha Proteobacteria |
| Genus: | Azospirillum |
| Species: | Azospirillum brasilense |
| Description: | Azospirillum brasilense is one of the most well-studied plant growth promoting bacteria. It is considered a free-living soil bacterium that has the ability to affect the growth of numerous agricultural crops worldwide through the excretion of various hormones and the bacteria’s ability of nitrogen fixation. Many countries use bacterial inoculants containing A.brasilense alone or in concert with other plant growth promoting bacteria. This organism was previously identified as Spirillum lipoferum. It is commonly isolated from the rhizosphere and plant tissues from a wide variety of plants and has been used as a model organism in the study of microbe-plant interaction. EST |

| Pathogenicity: | Azospirillum brasilense initially infects the root branches and spreads into the main roots. Production of plant hormones for cell elongation (auxins), cell division and growth (cytokinins) and stem elongation (gibberellins) by Azospirillum brasilense has been shown to increase the number of lateral roots and root hairs. |
