果蝇细胞内共生菌Wolbachia研究进展

摘要

Wolbachia是一类存在于包括绝大多数昆虫在内的节肢动物以及线虫体内的细胞内共生菌,通过母系传递给子代.该菌能以多种方式调控宿主的生殖活动,包括诱导细胞质不亲和、孤雌生殖、杀雄、雌性化和增加雌性生殖力.本文对Wolbachia的基础生物学及其分布、以及该菌对宿主果蝇的影响等进行了评述,并对与果蝇相关的Wolbachia的研究现状及趋势进行了讨论.%The symbiotic bacterial species Wolbachia pipientis is a maternally inherited, intracellular parasitic microbe common to arthropod species(including most insects)and some nematodes. This bacteria manipulates the reproduction of its hosts by different mechanisms, including cytoplasmic incompatibility, parthenogenesis inducing, male-killing,feminization and increase female fecundity. In this paper, previous studies on the interactions between Wolbachia and Drosophila is briefly surveyed and discussed.
