摘要:

分析了石鲈科4属10种鱼类S7核糖体蛋白基因内含子1部分序列特征, 采用MP法和NJ法构建系统发育树。结果表明,在分子系统树上, 10种石鲈科(Haemulidae)鱼类共组成两大类群, 其中髭鲷属(Hapalogenys)鱼类和胡椒鲷属(Plectorhynchus)鱼类聚成一类群, 石鲈属(Pomadasys)鱼类和仿石鲈属(Haemulon)鱼类聚成一类群, 两类群再聚成一支, 10种石鲈科鱼类构成单一分支类群。髭鲷属鱼类跟胡椒鲷属鱼类的亲缘关系较近。基于遗传距离分析表明, 相对于石鲈属, 髭鲷属鱼类跟仿石鲈属鱼类的遗传距离较小。因此, 研究结果支持髭鲷属的分类地位是介于胡椒鲷属和仿石鲈属之间, 未能从石鲈科中独立出来形成髭鲷科(Hapalogeniidae)。

Abstract:

Partial sequences of the 1st intron of S7 ribosomal protein gene among four genera and 10 species of Haemulidae fish were analyzed. A phylogenetic tree was constructed using the MP and NJ methods. The results show that 10 Haemulidae fishes were divided into two clades in the phylogenetic tree: with one clade composed of Hapalogenys and Plectorhynchus, and another, of Pomadasys and Haemulon, so the 10 Haemulidae fishes forming a monophyletic group. The genera Hapa-logenys and Plectorhynchus had a close relationship. Based on genetic distance, Hapalogenys and Haemulon were more closely related than Hapalogenys and Pomadasys. So our study supports the viewpoint that the phylogenetic position of Ha-palogenys was between Plectorhynchus and Haemulon and could not be upgraded to the family of Hapalogeniidae.
