Faunimonas pinastri gen. nov., sp. nov., an endophyte from a pine tree of the family Pleomorphomonadaceae, class Alphaproteobacteria

Bacterial strain A52C2 T was isolated from the endophytic microbial community of a Pinus pinaster tree trunk and characterized. Strain A52C2 T stained Gram-negative and formed rod-shaped cells that grew optimally at 30 °C and at pH 6.0–7.0. The G+C content of the DNA was 65.1 mol %. The respiratory quinone was ubiquinone 10, and the major fatty acids were cyclo-C 19:0 ω 8 c and C 18:0 , representing 70.1 % of the total fatty acids. Phylogenetic analyses based on the 16S rRNA gene sequences placed strain A52C2 T in a distinct lineage within the order Hyphomicrobiales , family Pleomorphomonadaceae . The 16S rRNA gene sequence similarities of A52C2 T to that of Mongoliimonas terrestris and Oharaeibacter diazotrophicus were 93.15 and 93.2 %, respectively. The draft genome sequence of strain A52C2 T comprises 4 196 045 bases with a 195-fold mapped coverage of the genome. The assembled genome consists of 43 contigs of more than 1 000 bp ( N50 contig size was 209 720 bp). The genome encodes 4033 putative coding sequences. The phylogenetic, phenotypic and chemotaxonomic data showed that strain A52C2 T (=UCCCB 130 T =CECT 8949 T =LMG 29042 T ) represents the type of a novel species and genus, for which we propose the name Faunimonas pinastri gen. nov., sp. nov.
