Roseiterribacter gracilis gen. nov., sp. nov., a novel filterable alphaproteobacterium isolated from soil using a gel-filled microwell array device
Our previous studies indicate the abundant and diverse presence of yet-to-be-cultured microorganisms in the micropore-filtered fractions of various environmental samples. Here, we isolated a novel bacterium (designated as strain TMPK1T) from a 0.45-μm-filtered soil suspension by using a gel-filled microwell array device comprising 900 microwells and characterized its phylogenetic and physiological features. This strain showed low 16S rRNA gene sequence identities (<91%) and low average nucleotide identity values (<70%) to the closest validly described species, and belonged to a novel-family-level lineage within the orderRhodospirillalesofAlphaproteobacteria. Strain TMPK1Texhibited small cell sizes (0.08–0.23 μm3) and had a high cyclopropane fatty acid content (>13%), and these characteristics were differentiated from otherRhodospirillalesbacteria. A comprehensive habitability search using amplicon datasets suggested that TMPK1Tand its close relatives are mainly distributed in soil and plant-associated environments. Based on these results, we propose that strain TMPK1Trepresents a novel genus and species namedRoseiterribacter gracilisgen. nov., sp. nov. (JCM 34627T= KCTC 82790T). We also proposeRoseiterribacteraceaefam. nov. to accommodate the genusRoseiterribacter.
Draft Genome Sequence of “ Candidatus Phytoplasma asteris” Strain OY-V, an Unculturable Plant-Pathogenic Bacterium
ABSTRACT Phytoplasmas are unculturable plant-pathogenic bacteria causing devastating damage to agricultural production worldwide. Here, we report the draft genome sequence of “ Candidatus Phytoplasma asteris” strain OY-V. Most of the known virulence factors and host-interacting proteins were conserved in OY-V. This genome furthers our understanding of genetic diversity and pathogenicity of phytoplasmas.
