Phylogenetic relationships among three newHemibarbusmitogenome sequences belonging to the subfamily Gobioninae (Teleostei, Cypriniformes, and Cyprinidae)

Abstract

Our findings are congruent with the previous taxonomic appraisal based on morphological analysis.

Phylogeny of the gudgeons (Teleostei: Cyprinidae: Gobioninae)

“…Within the latter group, there is a clear split into two lineages: one with Gobio and Romanogobio (the only two gudgeon genera with species native to Europe), and possibly Mesogobio; and the other with Abbottina, Biwia, Gobiobotia, Huigobio, Microphysogobio, Platysmacheilus, Pseudogobio, Saurogobio, and Xenophysogobio. The results presented herein match those from Yang et al (2006), Kim et al (2009), andLiu et al (2010), the previous molecular studies focusing on gobionine relationships. The distribution of specialized swim bladders indicates that that feature has evolved independently more than once within the subfamily.…”

“…Kottelat, 2006;Bogutskaya et al, 2008). This would disagree with Kim et al (2009), who found H. barbus and H. labeo as sister taxa, though they were unable to examine H. maculatus, which we found as the sister species of H. labeo ( Figs. 1 and 2).…”

“…Within Gobioninae, we found evidence for three primary clades. This division into three groups corresponds with the results presented by previous molecular studies (Yang et al, 2006;Kim et al, 2009;Liu et al, 2010). A revised classification of the subfamily Gobioninae and its member tribes based on our results is provided in Table 2.…”

“…Their topology found Gobioninae sister to a large clade that included Leuciscinae as well as members of the subfamilies Acheilognathinae, Cultrinae, and Xenocypridinae. Kim et al (2009), using whole mitochondrial genome sequences, found relationships among gobionines that were generally similar to those of Yang et al (2006), albeit with greatly reduced taxon sampling, examining only ten gobionines. Despite the limited taxa, Kim et al (2009) Yang et al (2006), an unsurprising result given the overlap in sequence data.…”

Identification and phylogenetic analysis of the mitochondrial genome of Hemibarbus labeo BML (Cypriniformes: Cyprinidae)

“…The mitogenome of H. labeo BML shows more closer relationship with other Hemibarbus fishes including H. labeo (Kim et al. 2009 ), H. barbus , H. maculatus , H. medius , H. umbrifer , H. mylodon , and H. longirostris. These results showed that, the mitogenome sequence can provide useful information in the taxonomy and conservation biology studies of H. labeo and other fish species.…”
