Matings of a number of Saccharomyces cerevisiae stocks give different output ratios of mitochondrial genotypes depending on whether the cells are glucose-repressed or derepressed. The effects of glucose repression are independent of cellular mating type and mitochondrial genotype, and take place at least in part after zygotes are formed. An explanation is proposed in terms of changes in the relative numbers of mitochondrial DNA molecules contributed by the a and alpha parents, modified by selective replication or destruction of molecules inside the zygote.
许多酿酒酵母菌株的交配会产生不同比例的线粒体基因型,这取决于细胞是处于葡萄糖抑制状态还是解除抑制状态。葡萄糖抑制的影响与细胞交配型和线粒体基因型无关,并且至少部分发生在合子形成之后。本文提出了一种解释,即a型和α型亲本贡献的线粒体DNA分子相对数量发生了变化,并受到合子内分子选择性复制或破坏的影响。
