Abstract: Nitrogen fixation is one of important ecological reactions sustaining productive force on the earth , only second to CO2 fixation .The non-leguminous woody dicotyledonous plants can fix nitrogen gas in symbiosis with actinomycete Frankia , which has very significant effects on soil restoration , fuel wood , production of wood and derivatives, agro-forestry , coastal restoration , and the prevention of desertification .These plants are important nitrogen suppliers among land ecological system.Frankia has the characteristics of extensive host ranges , higher nitrogenase activity and insensitive to oxygen , so it is very likely to establish a new symbiotic nitrogen-fixing system between Frankia and crops .Highly efficient engineering Frankia strains and new symbiotic nitrogen-fixing system obtained by the approaches and technologies of biological engineering will be the most important objectives in the field of biological nitrogen fixation in the future .We will focus on the research progress about Frankia genes involved nitrogenmetabolism (including nif gene organization , gln and gln Ⅱ ), genes related to nodulation such as nod genes , hemoglobin genes and other nodule-specific cDNA clones in root nodules formed by infection of Frankia in the paper .[ Ch , 33 ref .]
