© 2022, The Author(s). A genome-based polyphasic study was undertaken to establish the taxonomic status of an actinobacterium strain isolated from an actinorhizal root nodule. Strain ncl1T was found to have chemotaxonomic, cultural and morphological properties characteristic of members of the genus Nocardia. The strain was closely related to Nocardia aurea in the phylogenetic trees based on 16S rRNA gene and genome sequences. The draft genome of the strain is 8.9 Mbp in size, has a genomic DNA G + C content of 67.0% and was predicted to contain at least 19 biosynthetic gene clusters encoding for specialized metabolites. Strain ncl1T was distinguished from its closest neighbour, N. aurea DSM 103986T, by a broad range of phenotypic properties and by low average nucleotide identity and digital DNA-DNA hybridization scores. Consequently, the strain represents a novel Nocardia species for which the name Nocardia noduli sp. nov. is proposed. The type strain is ncl1T (CECT 30123T = DSM 110878T). The present study provides further evidence that actinorhizal nodules are a source of novel species of Nocardia.
