Genetic homologies among Streptomyces violaceoruber strains.

A M Monson, S G Bradley, L W Enquist, G Cruces.

Abstract

Most of the genetic studies on streptomycetes have been done with cultures erroneously designated as Streptomyces coelicolor. To determine whether these cultures are genetically homologous with the S. violaceoruber nominifer, their deoxyribonucleic acids (DNA) were analyzed, and selected pairs of mutants were crossed. The four cultures used in genetic studies, and called S. coelicolor in the literature, were found to constitute a genospecies, based upon DNA hybridization and recombination tests. In addition, DNA from Actinopycnidium caeruleum formed extensive duplexes with S. violaceoruber DNA. S. violaceoruber cultures and A. caeruleum were distinctly different from the S. coelicolor nominifer.
