黑腹果蝇的Punch基因编码蝶啶生物合成酶GTP环水解酶,在遗传上是复杂的。该基因座的致死等位基因可分解成一系列的等位基因互补组,并且至少有一类突变是发育特异的,只在成年人的头部影响GTP环水解酶的活性。所有以前分离的Punch等位基因都是根据突变的眼睛颜色表型确定的。通过筛选突变区缺失的突变染色体,我们现在已经根据致命和可见的表型分离出新的等位基因。这些等位基因大多属于以前发现的基因类别,但也发现了两种新的突变类别。一类包含两个等位基因,在某些遗传背景下表现为显性致命突变。另一类代表了第二组发育特定的等位基因,这些等位基因只在胚胎发育期间影响Punch基因座的功能。
The Punch locus of Drosophila melanogaster which encodes the pteridine biosynthetic enzyme, GTP cyclohydrolase, is genetically complex. Lethal alleles of the locus resolve into an array of interallelic complementation groups, and at least one class of mutations is developmentally specific, affecting GTP cyclohydrolase activity only in the heads of adults. All previously isolated Punch alleles were identified on the basis of a mutant eye color phenotype. By screening mutagenized chromosomes over Punch region deficiencies, we have now isolated new alleles on the basis of lethal and visible phenotypes. Most of these alleles fall into previously identified genetic classes, but two new classes of mutations were also found. One class contains two alleles that behave as dominant lethal mutations in some genetic backgrounds. The other class represents a second developmentally specific set of alleles that affect the function of the Punch locus only during embryogenesis.
