沃尔巴克氏体(Wolbachia)是一种广泛分布于昆虫体内的共生细菌,对宿主的生殖具有多种调控作用,其中,最常见的调控方式称为细胞质不亲和(Cytoplasmic Incompatibility,CI),即感染了Wolbachia的雄性宿主与未感染或感染不同品系Wolbachia的雌性宿主交配后,胚胎在发育早期死亡。关于CI产生的原因,目前人们认为是一种“精子修饰-卵子挽救”机制,本研究初步探索了黑腹果蝇中参与“修饰-挽救”机制的重要因子。本研究采用定量RT-PCR方法,检测了3种基因: yem-α(yemanuclein) 、uif(uninflatable) 、Prosα4T1(proteasome α4 subunit,Testis-specific 1)在感染和未感染果蝇中的表达差异。结果发现,Wolb...

Wolbachia are endosymbiotic bacterium that infect many insects. They can manipulate host reproduction by several mechanisms. Cytoplasmic incompatibility (CI) is the most common reproductive modification induced by Wolbachia and results in the developmental arrest of embryos when Wolbachiainfected males mate with uninfected females or with females infected by a different Wolbachia strain. Intriguingly,a female infected with the same strain of Wolbachia may rescue embryonic lethality associated with CI. The molecular mechanisms of CI are currentl...
