Abstract

Summary: The degree of binding was determined between DNA preparations from gordonae and rhodochrous strains and uracil-labelled DNA from five reference strains, Nocardia asteroides NK20, N. pellegrino PI I, Gordona bronchialis TI, G. terrae T5 and rhodochrous strain 90. Most of the rhodochrous and pellegrino strains fell into one of two genetically homogeneous taxa. The nucleotide sequence homology data also suggested that , and more equivocally , formed distinct species. However, the values for DNA relatedness betweenthese species, and between them and the rhodochrous homology groups, were comparatively low. Only a small degree of nucleotide sequence homology was found between the reference system and the rest of the taxa studied. The nucleotide composition of the DNA preparations from 29 of the 30 test strains fell between 63 and 69 mol % guanine plus cytosine.
