gen. nov., sp. nov., a new member of family isolated from stems of elmleaf blackberry ( Schott) in Northwest Spain.

Strain CRRU44 was isolated from the stems of plants growing in Salamanca (Spain). The phylogenetic analysis of the 16S rRNA gene sequence places this strain within the family showing that it is equidistant to the type species of several genera from this family with similarity values ranging from 91.0 to 96.3 %. Strain CRRU44 formed a divergent lineage which clustered with RZME27, HAMBI540 and R1-200B4. The phylogenomic analysis showed that strain CRRU44 was equal to or more distant from the remaining genera of the family than other genera among them. The calculated average nucleotide identity based on blast and average amino acid identity values with respect to the type species of all genera from the family were lower than 78.5 and 76.5 %, respectively, which are the currently cut-off values proposed to differentiate genera within this family. All these results together with those from phenotypic and chemotaxonomic analyses support that strain CRRU44 represents a novel species of a novel genus within the family , for which the name gen. nov., sp. nov. is proposed (type strain CRRU44=CECT 30117=LMG 31822).
