用线粒体Cytb基因序列探讨冬虫夏草寄主蝠蛾的系统进化关系

为探讨冬虫夏草寄主蝠蛾种属间的系统进化关系,采用CTAB法分别从18个冬虫夏草居群的虫草虫体头部和2种寄主蝠蛾中提取基因组DNA,PCR扩增获得冬虫夏草寄主线粒体Cytb基因片段序列.结合GenBank中的蝙蝠蛾科24种冬虫夏草寄主的同源序列,构建NJ系统树.结果表明,双栉蝠蛾属(Bipectilus)先于蝠蛾属(Hepialus)和类蝠蛾属(Hepialiscus)分化;蝠蛾属的冬虫夏草寄主种类众多形态各异,且均有特定的地理分布,蝠蛾属的种间遗传分化也较明显,蝠蛾属可能是多系起源;Cytb基因序列在冬虫夏草寄主蝠蛾种属间存在较丰富的变异,在蝠蛾属中除草地蝠蛾和金沙蝠蛾的该段序列完全一致外,其他种类蝠蛾种间变异率为0.23%—9.24%,Cytb基因序列可用于冬虫夏草寄主昆虫种的鉴定,但有必要获取更多种类的寄主昆虫来进一步验证.通过对冬虫夏草虫体头部提取的DNA进行PCR扩增获得其寄主蝠蛾Cytb基因序列的方法准确有效,有助于进一步获取更多的基因序列对更多的冬虫夏草居群和寄主种类进行系统发育、居群遗传结构及菌虫相互关系等研究.     

贡嘎蝠蛾幼虫肠道菌群的分析

贡嘎蝠蛾(Hepialus gonggaensis)幼虫是名贵中药材冬虫夏草(Cordyceps sinensis)的优势寄主.研究贡嘎蝠蛾幼虫肠道菌群,对研究蝠蛾的营养生理,提高幼虫成活率,进而人工培殖冬虫夏草具有重要意义.实验以四川康定采集的贡嘎蝠蛾为实验材料,对贡嘎蝠蛾幼虫的肠道细菌进行了分离和鉴定.实验结果表明,贡嘎蝠蛾肠道细菌都属低温菌,最适生长温度15 ℃,在15 ℃培养2 d后才长出典型菌落.从肠道中分离纯化出12个不同菌群,其中优势菌群为葡萄球菌,菌群数量为2.05×109 mL-1,检出率100%,应为幼虫肠道中的常住菌群,其它菌群检出率均低于50%,可能为肠道中的过路菌群.生化鉴定大多数菌群的符合值都较低,这与蝠蛾生活于高海拔高寒地区,其肠道微生物与常见微生物菌群有较大差异一致.

Mesozoic giant fleas from northeastern China (Siphonaptera): Taxonomy and implications for palaeodiversity

The recently discovered definite giant fleas from the Middle Jurassic Daohugou fauna and the Early Cretaceous Jehol fauna of northeastern China represent significant evidence for understanding ectoparasitism in the Mesozoic as well as the evolution of these giant blood feeders with their putative hosts (i.e. hairy or feathered vertebrates). On the basis of seven well-preserved specimens from Daohugou and Huangbanjigou we analyse the systematic classification of these primitive fleas, establishing two new genera and three new species as Pseudopulex wangi sp. nov., Hadropsylla sinica gen. et sp. nov., and Tyrannopsylla beipiaoensis gen. et sp. nov. All of them are assigned to the extinct siphonapteran family Pseudopulicidae, while the Early Cretaceous genus Tarwinia is transferred to Tarwiniidae fam. nov. The basal morphological disparities of Siphonaptera in the Mesozoic are evidenced by the occurrence of at least three distinct groups (pseudopulicids, tarwiniids, and saurophthirids). These disparate morphologies likely indicate adaptations to different hosts.
