中文摘要 | 本研究對於臺灣地區所採集之202筆煙草粉蝨族群,利用PCR反應對於煙草粉蝨二級內共生菌之16S rDNA及Wolbachia之表面蛋白基因(Wolbachia surface protein, wsp)的增幅,以進行內共生菌的偵測;結果顯示,臺灣地區55.4%的煙草粉蝨族群受二級內共生菌的感染,38.1%的族群受Wolbachia的感染,再經由類緣關係分析,感染臺灣地區煙草粉蝨之二級內共生菌皆為Proteobacteria γ-3亞綱的種類,而Wolbachia則屬於B群的Con/Rug亞群的種類。由各生物小種感染之比例顯示,此二類內共生菌之分布與生物小種有較密切的相關,然而影響其分布的因素仍需後續的研究以進一步釐清。 |
英文摘要 | The 16S ribosomal DNA (rDNA) of the secondary endosymbiont and Wolbachia-specific gene, wsp (cell surface protein of Wolbachia), were amplified and sequenced. Based on the occurrence of 16S rDNA and wsp by PCR, more than 55% and 38% of examined B. tabaci populations (n = 202) harbored secondary endosymbiont and Wolbachia, respectively. Molecular phylogenetic analysis of 16S rDNA sequences showed that the secondary endosymbiont was located in the γ-3 clade of a subdivision of the Proteobacteria. Wsp gene sequences revealed that the Wolbachia found in B. tabaci populations of Taiwan belong to group B and subgroup Con/Rug. The results also showed that the carrying/infection rate of secondary endosymbiont/Wolbachia might be related to the biotype of B. tabaci. |
