Genetic studies on polymeric genes for maltose fermentation were undertaken employing two species of Saccharomyces: Sacch. cerevisiae and Sacch. carlsbergensis.Through an extended series of hybridization involving the progeny of the hybrid Sacch. cerevisiae and Sacch. chevdieri, it was shown that three polymeric genes for maltose fermentation, MALA, MALB, and MALC (not yet identified with standard MAL genes), exist in first-named species, while the latter species lacks these genes and...

Genetic studies on polymeric genes for maltose fermentation were undertaken employing two species of Saccharomyces: Sacch. cerevisiae and Sacch. carlsbergensis.Through an extended series of hybridization involving the progeny of the hybrid Sacch. cerevisiae and Sacch. chevdieri, it was shown that three polymeric genes for maltose fermentation, MALA, MALB, and MALC (not yet identified with standard MAL genes), exist in first-named species, while the latter species lacks these genes and is therefore recessive.By crossing Sacch. carlsbergensis with Sacch. globosus, we found that Sacch. carlsbergensis possesses only one gene for maltose fermentation, MAL6, which Winge et al. had assumed to be present.These four genes for maltose fermentation were proved to be individual and non-linked.

用啤酒酵母及卡尔斯伯酵母研究麦芽糖发酵等效异位基因,对啤酒酵母与薛氏酵母的杂种后代进行一系列杂交,结果证明啤酒酵母含有3个等效异位基因MALA、MALB及MALC基因(暂定名,因未与标准MAL基因鉴定),而薛氏酵母不含任一MAL基因,故为隐性菌株。 在卡尔斯伯酵母与球形酵母杂交试验中,发现卡尔斯伯酵母只含有1个MAL6基因,证实了Winge等人的工作。 所有这4个麦芽糖发酵基因都是互相独立的不连锁的基因。

Through a series of extensive crosses of three species of Saccharomyces with recessive strains S. globosus or 8. chevalieri, genetic analyses of polymeric genes for fast maltose fermentation were undertaken by means of micromanipulation technique. The results were as follows: (1) A strain of S. cerevisiae (No. 2.982) contains two polymeric genes for fast maltose fermentation; MALI and MALII in different chromosomes. (2) A strain of 8. carlsbergensis (No. 2.500) contains only one gene for maltose...

Through a series of extensive crosses of three species of Saccharomyces with recessive strains S. globosus or 8. chevalieri, genetic analyses of polymeric genes for fast maltose fermentation were undertaken by means of micromanipulation technique. The results were as follows: (1) A strain of S. cerevisiae (No. 2.982) contains two polymeric genes for fast maltose fermentation; MALI and MALII in different chromosomes. (2) A strain of 8. carlsbergensis (No. 2.500) contains only one gene for maltose fermentation; MAL6. (3) We found that among the progeny of a hybrid of S. uvarum (No. 2,346) with 8. chevalieri, S. Uvarum possesses at least one gene for maltose fermentation, which is identical with MALI from 8. cerevisiae, but not identical with MAL6 from 8. carlsbergensis. (4) 8. globosus may be considered as a recessive parent as S. chevalieri to identify genes for maltose fermentation, since it contains following genes: malⅠ, malⅡ and mal6.In this paper, cross methods of comparing between haploid cells, a haploid cell with a spore and between spores were improved in some aspects, and discussed in detail. Various strains with monogene, and with different combinations of these genes as above, were obtained in our experiments.
