Azospirilla are generally regarded as rhizosphere bacteria and colonizethe root surface and only a few strains are able to infect plants. The stimulatoryeffect exerted by Azospirillum has been attributed to several mechanisms but undercertain environmental and soil conditions, Azospirillum can positively influenceplant growth, crop yields, and N-content of the legume. Most Azospirillum?rhizobacteriaco-inoculation studies have focused on the final effects on plant growth andnodulation parameters; in contrast, few data are available on the simultaneous effectof double inoculation and stressful conditions on the early signalling exchangebetween the symbiotic partners. Co-inoculation of legume with rhizobia plusAzospirillum exerted changes on the concentration, content, and/or distribution ofseveral mineral nutrients in roots and/or shoots of plants, change in flavonoids, andcan help to tolerate stress. This chapter summarized some effects that occur whenlegumes are co-inoculated with Azospirillum.
