本研究比較分析採自福隆、淡水、梧棲、臺西、東港、澎湖及馬祖等七個地區之43尾野生黑鯛及6尾養殖黑鯛粒線體DNA之D-loop區5'端段、D-loop區3'端段、tRNAPhe基因、及12S rRNA基因5'端段共718 bp之序列,以探討其序列之變異及其族群遺傳結構。 49尾黑鯛之粒線體DNA序列中,共發現33種基因型,其差異在於32個位置發生變異,其中30個發生在D-loop區5'端段,另2個發生在D-loop區3'端段;而且除了1個變異位置係顛換(transversion)及另一變異位置係缺失(deletion)之外,其餘30個變異位置均係轉換(transition)。兩兩基因型間之Tamura-Nei序列距離為0.0014-0.0127,依據序列距離使用UPGMA聚類方法繪出之基因型親緣關係樹並無明顯之系譜分支(genealogical branch)及地區標本群聚之情形,重複1000次bootstrap test所獲得親緣關係樹各分叉之bootstrap confidence level(BCL)?均小於50%。表示地理族群間分化程度之K?,在包括地區野生黑鯛及養殖黑鯛之8個樣本間為0.0829,而7個地區野生樣本間則為0.0805。這些結果顯示台灣及馬祖7個地區野生黑鯛間之遺傳分化輕微,應屬於同一族群;而野生黑鯛與養殖黑鯛間之遺傳分化亦不顯著。Tajima之測驗中性突變假說之統計?D為-1.5125,顯示黑鯛粒線體DNA序列之變異係中性突變(neutral mutation)所致。
Mitochondrial DNA sequences that include the 5' end of the D-loop region, the 3' end of the D-loop region, the tRNAPhe gene, and the 5' end of the 12S rRNA gene were determined from 49 specimens of Acanthopagrus schlegeli and 1 specimen of A. australis collected from 7 locations along the coastal waters of Taiwan and Matsu off the coast of mainland China, and from an aquaculture pond. Among 33 haplotypes identified from the 49 mtDNA sequences, there were 32 variable sites, most of which occurred in the 5' end of the D-loop region. Pairwise sequence distances among haplotypes, using the Tamura-Nei model, range between 0.0014 and 0.0127. The phylogenetic tree constructed by use of the unweighted pair-group method with arithmetic average shows neither significant genealogical branches nor geographic clusters. All of the bootstrap confidence levels resulting from 1000 bootstrap tests are below 50%. Furthermore, the sequence-statistics test reveals little genetic differentiation. Apparently, wild black porgies in the coastal waters of Taiwan and Matsu off the coast of mainland China, belong to a single population. There is no significant genetic differentiation between the wild and pond-cultivated populations.
