中文摘要 | 本研究運用粒線體兩個基因的去氧核醣核酸序列重構軍配飛蝨科群(Tropiduchidae- group)科間之類緣關係,分別是16S核醣體去氧核醣核酸(16S rDNA) 3' 端的400個鹼基及 細胞色素b基因(cytochrome b )之5'端的120個密碼位。整體而言,此二基因分析六個科十 個分類單元 (於16S核醣體去氧核醣核酸為九個分類單元)的結果彼此相符。類緣關係的分 析顯示,軍配飛蝨科(Tropiduchidae)及蛾蠟蟬科(Flatidae)聚類在一起;縞飛蝨科(Meenoplidae) 及飛蝨科(Delphacidae)分別位於基部:而圓飛蝨科(Issidae)不是一個自然的分類單元。當其它 各目昆蟲細胞色素b基因的DNA序列加入比對時顯示,轉換取代(transition)及顛換取代 (Transversion)的比值在蠟蟬總科(Fulgoroidea)內已趨近於穩定。另外,此二基因均可應用於 蠟蟬總科科間之類緣關係的研究,因為核酸序列的比對於屬內、近緣科間及疏遠科間的差異 各約10%、20%及30%。 |
英文摘要 | Wen-Bin Yeh, Chung-Tu Yang and Cho-Fat Hui (1998) Phylogenetic relationships of Tropiduchidae-group (Homoptera: Fulgoridea) of planthoppers inferred through nucleotide sequences. Zoological Studies 37(1): 45-55. Phylogenetic reconstruction of the relationships within the Tropiduchidae-group of families of planthoppers is conducted based on DNA sequences of 2 mitochondrial genes. The sequence comparisons of 400 basses of the 3' end of the 16S rDNA genes from 9 taxa of 6 families and 120 codons of the 5' end of the cytochrome b genes from 10 taxa of 6 families reveal general congruence. The phylogenetic trees based on these 2 genes show that Flatidae and Tropiduchidae are always grouped together; Meenoplidae and Delphacidae each is a basal lineage among these taxa, and lssidae is a nonhomogeneous group. The ratio of transitions over transversions of the cytochrome b gene in fulgorolds has reached a steady-state when compared with insects of other orders. Both genes can be candidated genes in studying the relationships of Fulgoroidea since the sequence variations of both genes between species of intragenus, close affinity families, and distant affinity families are about 10%, 20%, and 30%, respectively. |
