By using microcalorimetry method, we have studied ura auxotrophic mutant of saccharomyces cerevisiae AY, and 3 strains transformed from saccharomyces cerevisiae AY by plasmids.

Then at the 6 point will lead to a higher pregnancy rate. The reverse mutation frequency of the protoplast of the auxotrophic mutants was less than 10 ￣(-6).

营养缺陷型菌株原生质体回复突变率小于10￣（－6）。

Further investigation demonstrated that UV light decreased the mating ability of ade auxotrophic haploids and had no significant effect on the mating ability of other auxotrophic haploids.

研究表明：UV减弱了腺嘌呤缺陷型单倍体的交配能力，而对其它营养缺陷型单倍体的交配能力无甚影响；

Auxotrophic mutants of Trichoderma harzianum tolerant to carbendazim were obtained by UV-light mutagenesis and carbendazim induction on PDA medium.
