Species Identification of Anguillid Eels by Polymerase Chain Reaction / Restriction Fragment Length Polymorphism Analysis of the Gonadotropin II- βSubunit Gene

以促性腺激素 II-β基因片段之聚合?連鎖反應 / 限制?片段長度多型性分析法鑑別鰻魚種類

摘要


將9種鰻魚之促性腺激素 II-β基因片段以聚合?連鎖反應放大後,每一種鰻魚皆可得到單一之 DNA 產物。利用限制? Hpa II, Sph I以及 Nsi I 進行限制?片段長度多形性分析,可得到日本鰻(A. japonica);歐洲鰻(A. anguilla)以及雙色鰻(A. bicolor bicolor)三種不同之限制?圖譜,並且可與其他6種鰻魚-美洲鰻(A. rostrata)、澳洲鰻(A. australis australis)、東澳鰻(A. reinhardti)、西里伯斯鰻(A. celebesensis)、鱸鰻(A. marmorata)、以及太平洋雙色鰻(A. bicolor pacifica)所得之相同限制?圖譜區隔開。本結果提供一快速方便之聚合?連鎖反應 /限制?片段長度多型性分析方法,用以鑑別鰻魚種類。

Gonadotropin II beta-subunit gene (GTH II- β DNA) fragments of nine eel species of the genus Anguilla were amplified with specific oligonucleotides by polymerase chain reaction (PCR), and a single product was obtained from each species. In subsequent restriction fragment length polymorphism (RFLP) analysis of the PCR-amplified GTH II- β DNA, the restriction endonucleases Hpa II, Sph I, and Nsi 1 gave restriction patterns that differed among three species, e.g., Anguilla japonica, A. anguilla and A. bicolor bicolor, and from the other six species of anguillid eels,i.e., A. rostrata, A. australis australis, A. reinhardti, A. celebesensis, A. marmorata, and A. bicolor pacifica. Our results suggest that PCR/RFLP analysis provides a rapid and convenient method to discriminate eel species.
