Mutagenic specificity in response to chemical mutagens has been observed with certain temperature-sensitive mutants of reovirus type 3. One mutant induced by nitrous acid reverted specifically with nitrous acid. Three nitrosoguanidine-induced mutants reverted after nitrous acid treatment. These findings thus suggest that analysis of chemical induction of reversion from the temperature-sensitive phenotype may be a useful approach for studying the nature of mutation in animal viruses.
在呼肠孤病毒3型的某些温度敏感突变体中,已观察到对化学诱变剂的诱变特异性。一种由亚硝酸诱导的突变体仅能被亚硝酸特异性回复突变。三种由亚硝基胍诱导的突变体在亚硝酸处理后发生了回复突变。因此,这些发现表明,分析从温度敏感表型化学诱导回复突变,可能是研究动物病毒突变本质的一种有用方法。
