Abstract

The effects of SRO (Sex-ratio organism; previously called SR spirochetes) infection on the viability of gynandromorphs of D. melanogaster were examined. A fraction of gynadromorphs, most of them with small areas of XO tissue, survived, but the majority were not viable when XO nuclei or cells are affected by the infecting SRO. Apparently the replacement of lethal XO nuclei or cells by adjacent XX ones does not take place. Some possibilities are discussed as to the time and the primary site of the lethal action of SRO.

摘要

研究了性比生物(SRO,以前称为SR螺旋体)感染对黑腹果蝇雌雄嵌合体生存能力的影响。一部分雌雄嵌合体存活了下来,其中大多数XO组织区域较小,但当XO细胞核或细胞受到感染的SRO影响时,大多数则无法存活。显然,相邻的XX细胞核或细胞并没有取代致死的XO细胞核或细胞。文中讨论了关于SRO致死作用的时间和主要位点的一些可能性。
