对印度西太平洋地区6个群体的银鲳（Pampus argenteus）银鱼（Pampus argenteus）线粒体控制区的序列变异进行了分析。在165个个体的控制区464-466 bp片段中共检测到309个多态位点，定义了72种单倍型。单倍型多样性在0.800 ~ 0.943之间，核苷酸多样性在0.333%~ 1.886%之间。不同地理组间的遗传距离和固定指数差异显著（P < 0.05）。中位数连接的网络分析数据显示出不同的模式的地理结构。本研究结果表明，银汉鱼种群具有明显的遗传结构，特别是在地理隔离的群体之间。(C)2013爱思唯尔有限公司保留所有权利。
Sequence variation of the mitochondrial control region in silver pomfret (Pampus argenteus) among six populations from the Indo-West Pacific region was analyzed. A total of 309 polymorphic sites were detected in the 464-466 bp segment of the control region among 165 individuals which defined 72 haplotypes. Haplotype diversity was ranged from 0.800 to 0.943 and nucleotide diversity ranged from 0333% to 1.886%. Genetic distance and the fixation index indicated significant differences among populations in different geographical groups (P < 0.05). Median-joining network analysis data showed distinct patterns of phylogeographic structure. The present results suggested that P. argenteus populations have developed significant genetic structure, especially among geographically isolated groups. (C) 2013 Elsevier Ltd. All rights reserved.
