The strains used were a standard wild type strain (Canton-S) and a radiation sensitive strain (mei-41). Two-hundred adult males and about 6000 larvae of each strain were loaded and exposed to the cosmic environment. At the same time, almost the same number of adult flies and larvae were bred in the same environmental condition (temperature and humidity) as ground control groups. The flight period was about eight days. The returned male flies were mated with virgin female flies from a detection strain for investigating sex-linked recessive lethal mutation. X chromosomes with lethal genes were detected on the second generation. In the returned flies, the frequency of chromosomes with lethal genes was two times higher in the wild type strain and three times higher in the radiation sensitive strain than that of the ground control groups. Most of the returned larvae were in the pupal stage on the return day, and began to emerge on the next day. The emerged adult flies were stored in 70 percent alcohol solutions, and their wing samples were prepared for investigating the wing mutation spots derived from chromosome mutation. Mutation frequency in the wild type strain was almost the same between the flight and ground groups. The frequency in the Muller-5 individuals separated from the radiation sensitive strain was one and half times higher in the flight group than in the ground control group. However, the frequency in the radiation sensitive strain was significantly lower in the flight group than the ground group. The higher recessive lethal mutation frequency in the flight group suggests the synergistic effect of radiation and minute gravity on mutation induction in germ cells. However, this synergy effect was not observed on the chromosome mutation induction in somatic cells.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
