title: Life in grasses: diazotrophic endophytes.
abstract: N2-fixing bacteria such as Azoarcus spp., Herbaspirillum spp, and Acetobacter diazotrophicus can infect the interior of gramineous plants without causing symptoms of plant disease but do not survive in soil. Like phytopathogens, they can penetrate into central tissues and spread systemically. There is no evidence for an endosymbiosis in living plant cells; however, the bacteria are physiologically active in the plant apoplast.
