Effect of heat shock on the mutagenicity of mutagens and carcinogens in Euglena gracilis.
The effect of heat-shock treatment (42 degrees C for 15 min) on the ability of four mutagens and carcinogens to induce hereditary bleaching in Euglena gracilis cells was investigated. All four mutagens (treatment time: 1-24 h) tested after heat shock increased the frequency of bleached mutants of Euglena gracilis.
