Abstract

The degree of binding was determined between deoxyribonucleic acid (DNA) preparations from nocardiae and “rhodochrous” strains and uracil-labeled DNA from three reference strains, N668 and rhodochrous strains N11 and N54. In all cases, good congruence was found between the DNA reassociation data and that from numerical phenetic studies. Only a small degree of nucleotide sequence homology was found between the reference system and the other taxa studied, and there was evidence that is genetically heterogeneous. The moles percent guanine plus cytosine for the rhodochrous strains was within the range 58 to 67; the corresponding range for nocardiae was 64 to 68 mol%.
