Complete mitochondrial genome sequence of Brycon orbignyanus (Characiformes, Bryconidae)

Abstract

We report the whole mitochondrial genome of the Brycon orbignyanus, commonly known as the piracanjuba. The mitogenome was determined to be a circular, 16,800 bp DNA molecule, containing 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes and one 1160 bp noncoding control region. Twelve of the PCGs were located on the heavy strand, and one PCG (Nd6) was located on the light strand. The most common start codon was ATG; however, the Cox1 gene displayed the GTG start codon. Seven PCGs had incomplete stop codons: specifically, Cox2, Cox3, Nd3, Nd4, and Cytb contained the T- - codon, and Nd2 and Atp6 contained the TA- codon. The Cox1 gene contained the AGG stop codon.

Leporinus elongatus(Characiformes, Anostomidae): complete mtDNA sequence of an economically important fish from the Paraná and La Plata river basins

“…Only five out of 13 PCGs (ND1, ND2, ATPase8, ND4L and ND5) contained a TAA stop codon; four (COII, ND3, ND4 and Cytb) displayed incomplete termination codon (T-); three genes (ATPase6, COIII and ND6) displayed the incomplete TA-stop codon. Only COI presented AGG as stop codon, similar to others Characiformes (Siqueira et al 2014;Brandão-Dias et al 2016;Pimentel et al 2016); considered a vertebrate evolution (Osawa et al 1989). …”

“…The mitochondrial genome of L. elongatus was 16,784 bp (GenBank KU980144) solved with 205.16 folds of coverage. The GC content of the total sequence was 43%, with individual base content being: 29.9% A, 15.7% G, 27.1% T and 27.3% C. The mtDNA genome contains 2 rRNA and 22 tRNA genes, 13 protein-coding genes (PCGs) and a control region (D-loop) with 1115 bp, being consistent with mitochondrial genome structure of the fishes Carmo et al 2016;Chagas et al 2016;N uñez-Rodriguez et al 2016;Pimentel et al 2016;Resende et al 2016;Siqueira et al 2014). Only gene COI started with GTG codon, differing from all other PCGs that display the usual start codon ATG.…”

“…A study about the systematic and historical biogeography of the Bryconidae (Abe et al, 2014) show that the cis-and trans-Andean members of Brycon are not monophyletic and the relationship among cis-Andean species of this clade remain unresolved. Although the mitogenome of Brycon orbignyanus was recently published (Siqueira et al, 2014), a wider sampling of taxas and individuals are required to improve our understanding of the relationships between the families Bryconidae and Characidae. Thus, this work reports the complete mitochondrial genome of B. henni, an trans-Andean omnivorous fish considered as promising in aquaculture of temperate zones (Lenis et al, 2009).…”

Complete mitochondrial DNA ofHoplias intermedius(Günther, 1864) (Ostariophysi: Characiformes: Erythrinidae)

“…Taxonomic mislabeling represents an obstacle in forensic analysis. In this context, the characterization of mDNA, considering its well-conserved sequence, high abundance and small circular structure (Bilington & Hebert 1991;Pimentel et al 2014), represents a useful information source for species identification.…”

“…Four PCGs (ND1, ATPase8, ND4L, ND5) contained the complete TAA stop codon, similar to Salminus brasiliensis (Brandão-Dias et al 2016) and genus Prochilodus (Carmo et al 2016;Chagas et al 2016). One gene (COI) contained AGG as the stop codon, similar to Brycon orbignyanus (Siqueira et al 2014) and Piaractus mesopotamicus (Pimentel et al 2016). One gene (ND6) contained TGA as the stop codon, in contrast with other Bryconidae, Prochilodontidae and Serrasalmidae…”
