Phylogenetic measurement in procaryotes by primary structural characterization

Abstract

Oligonucleotide cataloguing has been used to characterize a number of 5S RNA species from various Procaryotes. Such catalogs can be used to establish certain and detailed phylogenetic relationships among organisms. Confining attention at present to four Families of Procaryotes, the Enterobacteriaceae, the Bacillaceae, the Achromobacteraceae, and the Pseudomonadaceae, we have shown that the conventionally accepted classification of these organisms which places the first three in the order Eubacteriales, and the last in the order Pseudomonadales, is not phylogenetically valid. © 1972 Springer-Verlag.
