摘要:
内生细菌影响兰科植物菌根形成和共生关系的稳定性,在兰科植物的生活史中起着重要作用。内生细菌通过分泌植物激素、采用光合作用、生物固氮或促进矿质营养的循环以及产生铁载体、合成其他活性物质等途径来促进兰科植物生长发育。综述了兰科植物内生细菌物种多样性的研究方法及其对兰科植物的促生机理,基于兰科植物与共生微生物的密切关系,认为内生细菌间、内生细菌与兰科植物菌根真菌间的互作是揭示兰科植物与内生细菌互作机理的重要方向。
关键词:  内生细菌  兰科植物菌根真菌  激素  生物固氮  铁载体

Abstract:
Endophytic bacteria play an important role in the life history of orchids,which influence the formation of mycorrhiza and stability of plant-fungi interaction. Endophytic bacteria could promote growth and development of orchids by secreting phytohormone, conducting photosynthesis, fixing nitrogen or promoting the cycle of mineral nutrition, producing siderophore and secreting other active substances. The research methods of the diversity of endophytic bacteria associated with orchids, and their growth-promoting mechanism were reviewed. Based on the close relationship between orchids and symbiotic microbe, the studies on interactions between endophytic bacteria and mycorrhizal fungi will be an important direction to reveal the mechanism of orchid-endophytic bacteria interaction.
Key words:  Endophytic bacteria  Orchid mycorrhizal fungi  Phytohormone  Fixing nitrogen  Siderophore
