Abstract

Representatives from various genera of the order Actinomycetales were investigated by comparative cataloging of their 16S ribosomal ribonucleic acids to establish their phylogenetic relationships. Members of Actinoplanes, Ampullariella, Dactylosporangium, and Micromonospora form one cluster that is peripherally related to the cluster defined by members of Mycobacterium, Nocardia, and Rhodococcus. Streptomyces griseus and strains of Chainia, Kitasatoa, Streptoverticillium, Microellobosporia, and Elytrosporangium are phylogenetically closely related, whereas Streptosporangium roseum is more distantly related to this cluster. Thermomonospora curvata and Geodermatophilus obscurus represent individual clusters. Promicromonospora citrea is a member of the Arthrobacter-Micrococcus-Cellulomonas line of descent. This grouping of organisms is highly supported not only by data from deoxyribonucleic acid-deoxyribonucleic acid homology studies and deoxyribonucleic acid-ribosomal ribonucleic acid cistron similarity studies but also by several common biochemical characteristics of proven taxonomic value.
