We isolated two sterile mutants of Schizosaccharomyces pombe. One of them was mapped close to ste13 (8 cM). Since it turned out to be allelic with the hitherto unmapped ral2, its linkage with ste13 localizes ral2 on the right arm of chromosome II. The other mutant defines a novel class-I ste gene, ste15, closely linked to ste7 (4 cM) on chromosome I. ste15 is conjugation-specific and acts upstream of pat1 and ras1. During its genetic analysis, a phenotypic suppression of ste12-N9 was observed which was caused by mutations in the unlinked gene ssw1.
我们分离出了粟酒裂殖酵母的两个无菌突变体。其中一个被定位在靠近ste13（8厘摩）的位置。由于它被证明与迄今未定位的ral2等位，其与ste13的连锁关系将ral2定位在第二条染色体的右臂上。另一个突变体定义了一个新的I类ste基因ste15，它与第一条染色体上的ste7紧密连锁（4厘摩）。ste15是接合特异性的，作用于pat1和ras1上游。在其遗传分析过程中，观察到ste12-N9的表型抑制，这是由非连锁基因ssw1中的突变引起的。
