AB - This work aims at exploring the co-aggregation of Azospirillum brasilense MTCC-125 with other plant growth promoting rhizobacterial (PGPR) strains. well. The benefits to plants by inoculation with Azospirillum have been primarily attributed to its capacity to fix atmospheric nitrogen, but also to its capacity to synthesize phytohormones, in particular indole-3-acetic acid. Brazil has a long tradition in the use of rhizobial inoculants, especially for the soybean crop, but it was only in 2009 that the first commercial inoculant carrying the plant-growth-promoting Azospirillum brasilense strains Ab-V5 (=CNPSo 2083) and Ab-V6 (=CNPSo 2084), identified by our research group, reached the market.

Maize ( Zea mays L.) is a major cereal crop worldwide and demands N fertilizers, which can be replaced partially by plant growth-promoting bacteria. 2003. 20, and also for co-inoculation of the legumes soybean ( Glycine ma x (L.) Merr.) Azospirillum is, certainly, the most employed PGPR in the world, but little is known about its interaction with rhizobia, when both are applied to legume seeds. The attachment of Azospirillum cells to plant roots occurs in two steps. The polar flagellum, of which the flagellin was shown to be a glycoprotein, mediates the adsorption step. 2.
