Abstract

The S character of Drosophila simulans SimES-st strain undergoes a non-mendelian transmission. It has been postulated that a virus, Drosophila S virus (DSV), could be the causative agent. Electron microscopy analysis of gonads of flies showing a strong S phenotype revealed the presence of virus in or near the germ cells. The S character transmission rate is greater in females than that in males. Similarly, the level of infection by DSV is higher in ovaries than that in testes. Flies treated at a nonpermissive temperature do not present the S phenotype and appear to be cured from the virus. This information, taken together with previous work, makes the hypothesis that DSV is the causative agent of the S phenotype more than likely.

摘要

拟暗果蝇SimES - st品系的S性状经历非孟德尔遗传传递。据推测，一种病毒，即果蝇S病毒（DSV），可能是致病因子。对表现出强烈S表型的果蝇性腺进行电子显微镜分析，发现在生殖细胞内或其附近存在病毒。S性状在雌性中的传递率高于雄性。同样，卵巢中DSV的感染水平高于睾丸。在非允许温度下处理的果蝇不表现出S表型，且似乎已从病毒感染中恢复。这些信息与之前的研究结果相结合，使得DSV是S表型致病因子这一假说极有可能成立。
