Gene conservation in Bacillus species. I. Conserved genetic and nucleic acid base sequence homologies.

Abstract
Interspecific transformation andnucleic acid hydridization have been used to study the relationship between eight members of the genus Bacillus. The results indicate a parallel between homology measured by genetic exchange and by nuclei acid hybridization. Also, the conclusion has been reached that among members of the genus Bacillus , there tends to be a conserved "core" of genetic material, including those genes which code for ribosomal and transfer RNA''s and those responsible for resistance to several antibiotics [streptomycin, erythromycin, micrococcin, and bryamycin].
