Abstract:
Bacterial strain A52C2T was isolated from the endophytic microbial community of a Pinus pinaster tree trunk and characterized. Strain A52C2T 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-C19:0 ω8c and C18:0, representing 70.1 % of the total fatty acids. Phylogenetic analyses based on the 16S rRNA gene sequences placed strain A52C2T in a distinct lineage within the order Hyphomicrobiales, family Pleomorphomonadaceae. The 16S rRNA gene sequence similarities of A52C2T to that of Mongoliimonas terrestris and Oharaeibacter diazotrophicus were 93.15 and 93.2 %, respectively. The draft genome sequence of strain A52C2T 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 A52C2T (=UCCCB 130T=CECT 8949T=LMG 29042T) represents the type of a novel species and genus, for which we propose the name Faunimonas pinastri gen. nov., sp. nov.
