弗兰克氏菌(Frankia spp.)能够与沙棘等非豆科植物形成根瘤进行共生固氮，其固氮效率远远高于豆科植物根瘤菌，与沙棘共生的弗兰克氏菌还能够促进沙棘对旱寒等各种不同生境的适应性，是自然界一类具有开发潜力的放线菌资源。为了更好地开发利用弗兰克氏菌资源，推进弗兰克氏菌分类鉴定工作，加强弗兰克氏菌与寄主植物共生结瘤固氮的机制研究，促使弗兰克氏菌在农业生产中得到尽快应用，本文简要介绍沙棘属(Hippophae L.)物种多样性、结瘤状况与分布特点、沙棘根瘤形态结构与功能、弗兰克氏菌物种多样性与分布特征，讨论弗兰克氏菌的结瘤机制、生理生态效应与作用机制以及影响沙棘属植物与弗兰克氏菌共生的主要因子，以期为进一步开展沙棘属植物弗兰克氏菌的系统研究提供有价值的参考。
Frankia spp. can form symbiotic nitrogen fixation with non-leguminous plants such as Hippophae spp., and its nitrogen fixation efficiency is much higher than that of legume rhizobia. Frankia spp. can also promote the resistance of drought and cold and the adaptability of various habitats for Hippophae spp.. Frankia spp. is a kind of actinomycete resources with developmental potential. The progress in Frankia spp. associated with Hippophae were introduced in order to develop and utilize Frankia spp., promote the classification and identification of Frankia spp., strengthen the mechanism of symbiotic nodulation and nitrogen fixation between Frankia spp. and host plants, and develop the application of Frankia spp. in agricultural as soon as possible. This paper reviews the research progress of the species diversity of Hippophae L., the nodulation status and distribution characteristics of Hippophae spp., as well as the morphology and functions of root nodules, the species diversity and distribution characteristics of Frankia spp. The nodulation mechanism of Frankia spp., the physiological and ecological effects of Frankia spp., and the main symbiotic factors of Frankia spp. and Hippophae were discussed. This review can provide valuable reference for systematic research on Frankia spp. associated with Hippophae L.
