We describe a new Frankia species, for three non-isolated strains obtained from Alnus glutinosa in France and Sweden, respectively. These strains can nodulate several Alnus species (A. glutinosa, A. incana, A. alnobetula), they form hyphae, vesicles and sporangia in the root nodule cortex but have resisted all attempts at isolation in pure culture. Their genomes have been sequenced, they are significantly smaller than those of other Alnus-infective species (5 Mb instead of 7.5 Mb) and are very closely related to one another (ANI of 100%). The name Candidatus Frankia nodulisporulans is proposed.

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene and draft genome sequences reported in this study for AgTrS, AgUmASt1 and AgUmASH1 are MT023539/LR778176/LR778180 and NZ_CADCWS000000000.1/CADDZU010000001/CADDZW010000001, respectively.

暂定弗兰克氏nodulisporulans SP。十一月,一种对nu虫(Alnus glutinosa)具有感染力的Frankia物种,无法在纯培养物中生长并且能够在植物体内形成孢子

我们描述了一种新的Frankia物种,分别来自法国和瑞典的Alnus glutinosa的三个非分离菌株。这些菌株可形成根瘤几个物种(A.黄A.香草A. alnobetula),它们形成在根瘤皮质菌丝,囊泡和孢子囊但在纯培养物抵制所有尝试在隔离。它们的基因组进行了测序,他们比其他的显著小-infective种(500万桶,而不是7.5 MB),并有很密切的关系彼此(100%ANI)。名称暂定弗兰克氏nodulisporulans建议。

本研究中针对AgTrS,AgUmASt1和AgUmASH1报道的16S rRNA基因的GenBank / EMBL / DDBJ登录号和基因组草案序列分别为MT023539 / LR778176 / LR778180和NZ_CADCWS000000000.1 / CADDZU010000001 / CADDZW010000001。
