我们的特点是一个新的显性等位基因的性别决定基因HER-1的秀丽隐杆线虫。该等位基因称为n695,导致XX动物不完全转化为表型雄性。先前表征的隐性her-1等位基因将XO动物转化为表型雌雄同体。我们已经确定了五个新的隐性her-1突变作为n695的基因内抑制因子。这些抑制基因中有三个是弱的、温度敏感的等位基因。我们发现,隐性HER-1突变是功能丧失的等位基因,HER-1(n695)突变导致HER-1基因座功能获得。显性和隐性等位基因的存在,导致相反的表型转换表明,她-1基因的行为,以控制性别身份在C。优雅的。
We have characterized a novel dominant allele of the sex-determining gene her-1 of Caenorhabditis elegans. This allele, called n695, results in the incomplete transformation of XX animals into phenotypic males. Previously characterized recessive her-1 alleles transform XO animals into phenotypic hermaphrodites. We have identified five new recessive her-1 mutations as intragenic suppressors of n695. Three of these suppressors are weak, temperature-sensitive alleles. We show that the recessive her-1 mutations are loss-of-function alleles, and that the her-1(n695) mutation results in a gain-of-function at the her-1 locus. The existence of dominant and recessive alleles that cause opposite phenotypic transformations demonstrates that the her-1 gene acts to control sexual identity in C. elegans.
