Temperature-sensitive mutants were isolated from a tetracycline resistance plasmid, pSC101, after mutagenesis with hydroxylamine. They were divided into three classes according to their growth characteristics. They include mutants defective in the replication of plasmid deoxyribonucleic acid and strains having a mutation in the drug resistance gene.
Hashimoto et al. (1976) studied this question.
