摘要
用 P C R 方法检测了多种果蝇中共生菌 W olbachia 的感染,发现 Drosophila auraria 复合种以及采集于北京地区的 Drosophila sim ulans为 Wolbachia 所感染, R F L P分析证实为单一感染.克隆了编码 W olbachia 外膜蛋白质的 w sp 基因并进行了序列测定.同时比较了 Drosophila auraria 复合种内 4 个种和采集于北京及美国加州的 Drosophila sim ulans 的线粒体的细胞色素氧化酶 2 亚基基因的部分序列. 进而讨论了 Wolbachia 对 Drosophila auraria 复合种成员之间进化关系的影响.
