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.
诸如固氮弧菌属、草螺菌属和固氮醋杆菌等固氮细菌能够侵染禾本科植物内部而不引发植物病害症状，但无法在土壤中存活。与植物病原体一样，它们能够穿透进入中央组织并进行系统传播。目前尚无证据表明在活的植物细胞中存在内共生现象；然而，这些细菌在植物质外体中具有生理活性。
