Pimelodus maculatus (Siluriformes, Pimelodidae): complete mtDNA sequence of an economically important fish from the São Francisco river basin

Comparative analysis of the mitogenomes of two Corydoras (Siluriformes, Loricarioidei) with nine known Corydoras, and a phylogenetic analysis of Loricarioidei

“…The 13 PCGs of the two new mitogenomes and those of the previously published nine mitogenomes of Corydoras contained COI-COIII, ND1-ND6, ND4L, two AT-Pases, and one Cyt-b, similar to that in other Siluriformes (Nakatani et al 2011;Liu et al 2016;Moreira et al 2016b;Resende et al 2016;Magalhães et al 2017;Parente et al 2017;Moreira 2018;Parente et al 2018;Pereira et al 2019;Ren et al 2019;Rocha-Reis et al 2020;Meng et al 2021;Zhang et al 2021). The total lengths of PCGs in the eleven mitogenomes of Corydoras were 11,400-11,414 bp, accounting for 67.84-69.24% of the entire mitogenome.…”

“…1, Table 2). The 44 mitogenomes of Siluriformes (Nakatani et al 2011;Liu et al 2016;Moreira et al 2016bMoreira et al , 2018Resende et al 2016; Magalhães et al 2017;Parente et al 2017;Parente et al 2018;Pereira et al 2019;Ren et al 2019;Rocha-Reis et al 2020;Meng et al 2021;Zhang et al 2021) used in this study were compared, and the gene composition and order were consistent (Suppl. material 1: Fig.…”

“…Phylogenetic trees for the eleven mitogenomes of Corydoras within the family Callichthyidae and Suborder Loricarioidei were constructed by aligning 13 PCGs and two rRNA sequences with those of 42 species of Loricarioidei, 29 species from Loricariidae , and one species from Trichomycteridae (Table 1 ). The mitogenomes of Pterocryptis cochinchinensis ( Resende et al 2016 ) and Silurus asotus ( Nakatani et al 2011 ) (accession no. NC_027107.1 and NC_015806.1 , respectively, suborder Siluroidei ) were included as outgroups to root the Loricarioidei tree.…”

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

“…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.…”

Molecular Evidence Reveals Taxonomic Uncertainties and Cryptic Diversity in the Neotropical Catfish of the Genus Pimelodus (Siluriformes: Pimelodidae)

“…The database analyzed in the present study included 83 COI sequences of Pimelodus specimens collected during previous studies in a number of different South American basins ( Supplementary Table S2 ). These areas include the Maroni River [ 26 ], the basin of the Magdalena–Cauca and Orinoco Rivers [ 23 ], the Amazon River [ 27 , 28 ], the São Francisco River [ 29 , 30 ], the Paraíba do Sul River [ 31 ], the Paraguay River [ 32 ], the upper and lower Paraná basins [ 33 , 34 , 35 , 36 ], and the plains of the Argentinian Pampa [ 37 ]. In all these cases, the taxonomic identification of the species followed the original denomination presented in the respective study.…”
