Wolbachia和WO噬菌体的侵染关系及稳定性

WO噬菌体是侵染节肢动物体内Wolbachia的细菌病毒。人们猜测WO噬菌体可能参与控制寄主遗传改变的活动。对WO噬菌体与Wolbachia的侵染关系以及WO噬菌体在米蛾Corcyra cephalonica、黑腹果蝇Drosophila melanogaster不同地理种群和世代间存在的稳定性进行初步研究。结果表明,WO噬菌体是侵染胞内菌Wolbachia的专性病毒,WO噬菌体稳定的存在于米蛾和黑腹果蝇的种群和世代中。据此推测,WO噬菌体与Wolbachia很可能经历长期的协同进化过程。

Infection and stability of Wolbachia and WO phage

WO phage is bacterial virus infecting Wolbachia in arthropods. It is suggested that WO phage may participate in controlling genetic change of the hosts. In this paper, the infection relationship between Wolbachia and WO phage, as well as the stablility of WO phage in different generations and geographical populations of Corcyra cephalonica and Drosophila melanogaster were studied. The results showed that WO phage was special virus infecting Wolbachia, and Wolbachia and WO phage stably existed in different generations and geographical populations of C. cephalonica and D. melanogaste. It indicates that WO phage and Wolbachin might have had a long and stable coevolution.
