摘要
研究了酿酒酵母（Saccharomycescerevisiae）单倍体突变株YNN-27-24（atrpura）对乳酸抗性产生原因及其遗传特性。结果表明，该突变株对乳酸的抗性不是由于对环境条件的适应，而是由基因突变所致。通过对A13-18（alys）和YNN-27-24进行杂交得到的30株杂交子代的遗传特性进行分析可以看出，YNNM-27-24突变株对乳酸和潮霉素B（HygromycinB）的抗性，均由单基因控制，并且，该突变株抗L-乳酸与抗潮霉素B基因之间存在着非常紧密的连锁关系。
This paper mainly deals with the reason of a haploid mutant YNN-27-24(a trp ura)of Saccharoopces cerevisiae to lashc acid tolerance as well as genetic analysis of the mutant.It was observed that the reason of mulct against lastic acid does not adapt to environmentalcondition, but lies in the gene mutation. From the analysis of 30 crossers crossed by A13-18 (alys ) and YNN-27-24, the results show that the growth chaleters of YNN-27-24 of L-lacticacid and hygromycin B tolerance are controlled by single gene and the genes have closerelationship betWeen them.
