Genomic insights into Gordonia diversity: proposal of three novel species (Gordonia. altitudinis sp. nov., Gordonia. ligustrum sp. nov., and Gordonia. pistacia sp. nov.) with distinct environmental and biomedical traits.

ABSTRACT:

Background

Rare actinomycetes, particularly Gordoni spp., are emerging as critical sources of bioactive metabolites and opportunistic pathogens.

Results

In this study, we isolated three novel Gordonia strains from soil samples and characterized their taxonomic status using a polyphasic taxonomic approach. Phylogenetic analysis of 16S rRNA genes and whole-genome comparisons indicated that strains CPCC 205333 ^T, CPCC 205515 ^T, and CPCC 206044 ^T represent three distinct novel species. The overall genome relatedness indices of average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) between these studied strains and their related type strains of the genus Gordonia were all below the established thresholds for species delineation
