The RAPD analysis of haploid strain of thermotolearnt yeast

The haploid strains HZ line from the thermololeant strain HU\|TY\|1 of Saccharomyces cerevisiae have been obtained by sporulation, and the analysis of growth and fermentation test was performed. The strains HZ\|21 and HZ\|84 were used as the ana lysis of random amplified polymerphic DNA (RAPD).The result showed that there were some polymorphic DNA fragments of genomic DNA among haploid, the diploid parent strain HU\|TY\|1 and the original strain LK, some of them may be correlation with thermotolerant property.
