Three sex-transforming genes (ix, tra-D, and dsx) in D. melanogaster were examined with respect to possible interactions with the NSR strain SR-spirochetes. The SR-spirochetes exerted a lethal effect on XY but not on XX individuals, regardless of whether they were phenotypically males, intersexes, or females. These results, taken together with those reported by Sakaguchi and Poulson (1963)on tra and 2X3A intersexes, both of which are resistant to the androcidal action of SR-spirochetes, support the interpretation that male susceptibility is a consequence of the single X condition.
针对黑腹果蝇中的三个性别转换基因(ix、tra-D和dsx),研究了它们与NSR菌株螺旋体可能存在的相互作用。无论XY个体表型为雄性、雌雄间性还是雌性,SR螺旋体对XY个体都有致死作用,而对XX个体则无致死作用。这些结果,再结合坂口和波尔森(1963年)关于tra和2X3A雌雄间性的报道,这两者都对SR螺旋体的杀雄作用具有抗性,支持了以下解释:雄性易感性是单X条件的结果。
