Abstract

A polyphasic taxonomic approach was used to characterize a previously isolated plant growth-promoting strain designated as NT2 and a strain designated as TKP (JCM 19688), both of which were found to manipulate plant stomatal immunity. Both strains shared 100% 16S rRNA gene sequence identity. Phylogenetic trees based on single and concatenated sequences of the housekeeping genes , , and 16S rRNA, as well as whole-genome sequences, clustered NT2 and TKP together, clearly separated from the closest spp., which belonged to the complex. NT2 showed average nucleotide identities (ANIs) of 87.8% (ANIb) and 89.9% (ANIm) and a 37.4% digital DNA–DNA hybridization score with DSM 17515, the species with the highest genome sequence similarity. On the contrary, the comparison between NT2 and TKP showed very high ANI (ANIb=99.67, ANIm=99.93) and digital DNA–DNA hybridization scores (98.90%). NT2 and TKP differed from closely related species in relation to arginine dihydrolase activity, aesculin and gelatin hydrolysis, -acetyl--glucosamine, maltose, adipate, phenylacetate, p-hydroxy-phenylacetic acid, Tween 40, glycyl--proline, -maltose, -galactonic acid lactone, -hydroxy butyric acid, myo-inositol, sucrose, -histidine, -malic acid, -rhamnose and acetic acid assimilation, NaCl-tolerance range and pyocyanin production (fluorescence on King A medium). The major fatty acids in NT2 and TKP were C16 : 0, C16 : 1 and C18 : 1. The results of this polyphasic study allowed the genotypic and phenotypic differentiation of NT2 and TKP from the closest and confirmed that these strains represent a novel species, for which the name sp. nov. is proposed with NT2 (DSM 114757=LMG 32751) as the type strain.
