摘要
弗兰克氏菌(Frankia)能够与大约25个属的非豆科植物共生进行结瘤固氮,在生态系统中具有重要意义。本文对Frankia的基因组学研究进展进行了综述,包括Frankia基因组的结构、功能及其表达特点,同时比较了来源于不同菌株的固氮基因的差异,并提出今后的发展趋势。
Nitrogen-fixation symbiosis between non-legume plants and Frankia stratus is the predominant N2- fixing system in forests. Actinomycete Frankia is of fundamental and ecological importance for its ability to fix nitrogen and to nodulate about 25 genera of plants. Here is a review on genomes of Frankia, including the organization, function, localization and some particular properties of its genes. Also a comparative analysis of Frankia nif genes from various strains and species was carded out. Novel trends in research on Frankia genetics were given in the end.
