沃尔巴克氏菌是一种广泛传播的母源性胞内细菌,可感染大多数昆虫物种,并能够改变无数宿主的繁殖。这些变化的细胞基础在很大程度上仍不清楚。在这里,我们报告了感染了本地Wolbachia wMau菌株的毛果蝇产生的产卵量是未感染的果蝇的四倍。沃尔巴克氏菌感染导致生殖系干细胞(GSCs)有丝分裂活性增加,生殖室细胞程序性死亡减少。我们的结果表明,GSCs分裂的上调是由Wolbachia对生殖系干细胞生态位(GSCN)的嗜好所介导的,GSCN是支持GSCs的细胞微环境。
Wolbachia are widespread maternally-transmitted intracellular bacteria that infect most insect species and are able to alter the reproduction of innumerous hosts. The cellular bases of these alterations remain largely unknown. Here we report that Drosophila mauritiana infected with a native Wolbachia wMau strain produces about four times more eggs than the non-infected counterpart. Wolbachia infection leads to an increase in the mitotic activity of germline stem cells (GSCs) as well as a decrease in programmed cell death in the germarium. Our results suggest that upregulation of GSCs division is mediated by a tropism of Wolbachia for the germline stem cell niche (GSCN), the cellular microenvironment that supports GSCs.
