Abstract

In recent years, the results of genome-based phylogenetic analyses have contributed to microbial systematics by increasing the availability of sequenced microbial genomes. Therefore, phylogenomic analysis within large taxa in the phylum Actinobacteria has appeared as a useful tool to clarify the taxonomic positions of ambiguous groups. In this study, we provide a revision of the actinobacterial family Streptosporangiaceae using a large collection of genome data and phylogenomics approaches. The phylogenomic analyses included the publicly available genome data of the members of the family Streptosporangiaceae and the state-of-the-art tools are used to infer the taxonomic affiliation of these species within the family. By comparing genome-based and 16S rRNA gene-based trees, as well as pairwise genome comparisons, the recently described genera Spongiactinospora and Desertactinospora are combined in the genus Spongiactinospora. In conclusion, a comprehensive phylogenomic revision of the family Streptosporangiaceae is proposed.
