Nocardia canadensis strain WB46 was isolated from the rhizosphere of willow plants (Salix purpurea L.) growing in soil contaminated with petroleum hydrocarbons in Varennes, Quebec, Canada. It exhibits a 7.15 Mb (69.55% GC content) draft genome sequence containing 6,387 protein-coding genes, 51 tRNA and 15 rRNA sequences, with many genes responsible for petroleum hydrocarbon degradation such as alkane 1-monooxygenase (alkB) and naphthalene dioxygenase (ndo). 16S rRNA gene analyses, including in silico DNA-DNA hybridization (DDH) and average nucleotide identity (ANI), between Nocardia sp. strain WB46 and a closely related strain, Nocardia asteroids, showed a distance of 63.4% and sequence identity of 88.63%, respectively. These values are below the threshold levels of 70% and 95%, respectively, suggesting that Nocardia canadensis strain WB46 is a new species.
