Abstract

Nonmating mutants were also isolated from haploid strains of yeast of both mating types. The mutants were characterized with respect to their ability to produce and respond to specific yeast sex factors, their ability to mate at low frequencies, and the ability of the low-frequency diploids to sporulate. Loss of the ability to mate by either mating type was invariably accompanied by the loss of one or more, and in some cases, all, of the above capabilities. The results strongly indicate that the sex factors are functionally involved in the conjugation process.

摘要

也从两种交配型的酵母单倍体菌株中分离出了不交配突变体。对这些突变体在产生和响应特定酵母性因子的能力、在低频率下交配的能力以及低频二倍体形成孢子的能力方面进行了表征。任何一种交配型丧失交配能力总是伴随着上述一种或多种能力的丧失,在某些情况下,所有能力都会丧失。结果有力地表明,性因子在接合过程中发挥着功能作用。
