Characterization of the mitochondrial genome and phylogeny of the black arowana (Osteoglossum ferreirai)

Abstract

In this study, we sequenced and assembled the mitochondrial (mt) genome of Osteoglossum ferreirai to re-assess the phylogenetic relationship of the family Osteoglossidae. We determined that the mitogenome of O. ferreirai contains the entire set of 37 mt genes, and the nucleotide composition and gene arrangement were similar to those of other bonytongues. Our phylogenetic analyses exhibited monophyly of the family Osteoglossidae with high bootstrap support, which is in agreement with the currently accepted phylogenetic viewpoint that is based on both morphological and molecular approaches. These findings provide additional informative data for the further study of phylogenetic relationships and help to elucidate a key component of the species radiation process within the family Osteoglossidae.

Complete mitochondrial genome from South American catfish Pseudoplatystoma reticulatum (Eigenmann & Eigenmann) and its impact in Siluriformes phylogenetic tree

“…In addition, one large non-coding region (922 bp), corresponding to the control region (D-Loop) was observed between tRNA Pro and tRNA Phe . Base composition analysis revealed the control region is richer in AT (64.97%, Table 3) than the remaining of the mitogenome (56.08%), as previously reported (Mu et al 2014(Mu et al , 2015. Important regulatory elements for the replication and expression of the mitogenome were found in three domains of the D-Loop (Fig.…”

“…Complete mitochondrial genomes have been typically obtained through sequencing of PCR-amplified overlapping fragments (e.g., He et al 2011;Hrbek and Farias 2008;Mu et al 2014;Wang et al 2014). The rapid progress observed in different NGS technologies has greatly increased the number of complete mtDNA sequences made publicly available for different fish species, including tropical siluriformes, such as the trans-andean shovelnose catfish (Sorubim cuspicaudus, Restrepo-Escobar et al 2014) and Pseudoplatystoma magdaleniatum (Rangel-Medrano et al 2015).…”

Karyotype of the african weakly electric fish, <i>Gymnarchus niloticus</i> (Osteoglosiformes: Gymnarchidae) from Oluwa River, Nigeria

“…Till date, information on the evolutionary relationship among the bonytongues have relied largely on morphological, osteological (Li and Wilson, 1996;Hilton, 2003) and molecular data (Kumasawa and Nishida, 2000; Lavoue and Sillivan, 2004;Mu et al, 2014). A more robust approach should be one that incorporates cytogenetic information in addition to these other sources of data.…”
