Diploids were selected from a mixture of radiation-sensitive, temperature-resistant and radiation-resistant, temperature-sensitive haploids on the basis of simultaneous radiation and temperature resistance. Analysis of drug-resistant haploid segregants of the heterozygous diploids indicated that one of the radiation-sensitive mutations, radA20, was linked to linkage group 1 whereas the other, radB13, was linked to the recently defined linkage group VI., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-97-1-1
