A novel strain of the genus Promicromonospora, designated PT9^T, was recovered from irradiated roots of the xerophyte Panicum turgidum collected from the Ksar Ghilane oasis in southern Tunisia. Strain PT9^T is aerobic, non-spore-forming, Gram- positive actinomycete that produces branched hyphae and forms white to yellowish-white colonies. Chemotaxonomic features, including fatty acids, whole cell sugars and polar lipid profiles, support the assignment of PT9^T to the genus Promicromonospora. The genomic relatedness indexes based on DNA-DNA hybridization and average nucleotide identity values revealed a significant genomic divergence between strain PT9^T and all sequenced type strains of the taxon. Phylogenomic analysis showed that isolate PT9^T was most closely related to Promicromonospora soli CGMCC 4.7398^T. Phenotypic and phylogenomic analyses suggest that isolate PT9^T represents a novel species of the genus Promicromonospora, for which the name Promicromonospora panici sp. nov. is proposed. The type strain is PT9^T (LMG 31103^T = DSM 108613^T).The isolate PT9^T is an ionizing-radiation-resistant actinobacterium (D₁₀ value = 2.6 kGy), with resistance to desiccation and hydrogen peroxide. The complete genome sequence of PT9^T consists of 6,582,650 bps with 71.2% G+C content and 6291 protein-coding sequences. This genome will help to decipher the microbial genetic bases for ionizing-radiation resistance mechanisms including the response to oxidative stress.
