由于遗传数据有限,Sciaenidae家族的系统发育状态存在不确定性和争议。在这项研究中,一个69,098bp的数据集,涵盖309个共享直系同源基因,从属于Sciaenidae家族的12种物种的18个基因组和5个转录组中提取,并用于系统发育分析。使用最大似然(ML)和贝叶斯方法(BA)方法来重建系统发育树。解析的ML和BA树显示出相似的拓扑结构,从而揭示了Sciaenidae家族中的两个主要进化谱系,即,西大西洋(WA)和东大西洋-印度-西太平洋(EIP)。WA组包括属于四个属的四个物种:Cynoscion nbulosus,马尾刺,Sciaenopsocellatus,和微孢子虫。同时,EIP组形成了一个单系进化枝,藏有8种(Argylesomusregius,A.刺槐,Pennahiaanea,Nibeaalbiflora,Miichthysmiiuy,Collichthyslucidus,Larimichthyspolyactis,和大黄鱼)来自六个属。我们的结果表明,在所研究的物种中,西大西洋(WA)群更为古老,而东大西洋-印度-西太平洋(EIP)组是一个年轻的组。在所研究的物种中,Collichthys和Larmichthys属是最年轻的血统,我们不建议将Collichthys和Larmichthys视为一个属。然而,由于缺乏基因组,Sciaenidae家族的起源和有关基础属的问题尚未解决。因此,需要进一步的采样和测序工作.
Uncertainty and controversy exist in the phylogenetic status of the Sciaenidae family because of the limited genetic data availability. In this study, a data set of 69,098 bp, covering 309 shared
orthologous genes, was extracted from 18 genomes and 5 transcriptomes of 12 species belonging to the Sciaenidae family and used for phylogenetic analysis. The maximum likelihood (ML) and Bayesian approach (BA) methods were used to reconstruct the phylogenetic trees. The resolved ML and BA trees showed similar topology, thus revealing two major evolutionary lineages within the Sciaenidae family, namely, Western Atlantic (WA) and Eastern Atlantic−Indo−West Pacific (EIP). The WA group included four species belonging to four genera: Cynoscion nebulosus, Equetus punctatus, Sciaenops ocellatus, and Micropogonias undulatus. Meanwhile, the EIP group formed one monophyletic clade, harboring eight species (Argyrosomus regius, A. japonicus, Pennahia anea, Nibea albiflora, Miichthys miiuy, Collichthys lucidus, Larimichthys polyactis, and L. crocea) from six genera. Our results indicated that the Western Atlantic (WA) group was more ancient in the studied species, while the Eastern Atlantic−Indo−West Pacific (EIP) group was a younger group. Within the studied species, the genera Collichthys and Larmichthys were the youngest lineages, and we do not suggest that Collichthys and Larmichthys should be considered as one genus. However, the origin of the Sciaenidae family and problems concerning the basal genus were not resolved because of the lack of genomes. Therefore, further sampling and sequencing efforts are needed.
