氮的可利用性常常限制陆地生态系统中的植物生长。平衡土壤或生态系统中氮损失的唯一生物反应是生物固氮，即N-2酶还原为氨。一些禾本科作物，如某些巴西甘蔗品种或卡拉草，可以从生物固氮中获得相当大部分的植物氮。我们对草相关固氮生物的研究集中在内生细菌，微生物在植物内繁殖和传播，而不会对宿主植物造成损害或对植物造成生态威胁。本文综述了固氮内生菌Azoarcus sp. BH 72的研究进展。(C)2003 Elsevier B. V.保留所有权利。
The availability of nitrogen often limits plant growth in terrestrial ecosystems. The only biological reaction counterbalancing the loss of N from soils or ecosystems is biological nitrogen fixation, the enzymatic reduction of N-2 to ammonia. Some gramineous crops such as certain Brazilian sugar cane cultivars or Kallar grass can derive a substantial part of the plant nitrogen from biological nitrogen fixation. Our research on grass-associated diazotrophs focuses on endophytic bacteria, microorganisms that multiply and spread inside plants without causing damage of the host plants or conferring an ecological threat to the plant. This review summarizes the current knowledge on the diazotrophic endophyte Azoarcus sp. BH72, which is capable of colonizing the interior of rice roots, one of the globally most important crops.
