Genetic variation and phylogenetic analysis of Indonesian indigenous catfish (baung fish) based on mitochondrial 12S rRNA gene

The complete mitochondrial genome of Mystus gulio Hamilton (Siluriformes: Bagridae) and its phylogenetic implication

Mystus gulio Hamilton, also called long whiskers catfish, is an endemic fish and a common food in some Asian countries. In this study, the complete mitochondrial genome of M. gulio was sequenced using the MinION system (Oxford Nanopore Technologies). The mitochondrial genome is 16,518 bp in length (41.1% [G + C] content) and consists of 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The results of phylogenetic analysis inferred from whole mitochondrial genomes of Mystus and related species in the family Bagridae revealed that M. gulio is closely related to Mystus cavasius.

New complete mitogenome datasets and their characterization of the European catfish (Silurus glanis)

We present new complete mitogenome sequences of Silurus glanis (S. glanis) from 4 samples such as male and female individuals from two countries (Hungary, Czech Republic). The complete mitochondria were determined from genome sequencing by using Illumina MiSeq platform resulting in long, 300 bp. paired-end reads. De novo assembly was performed resulting in one nod (scaffold) covering the total mitochondria in each sample. The mitochondrial genomes were circular, double-stranded molecules of 16,524 bp in length and consisted of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 control region. These sequences were deposited in the NCBI GeneBank under the accession numbers (MW796040, MW796041, MW796042, MW796043) and compared with the only available S. glanis mitochondrial genome (NC_014261.1) sequenced by unidentified technology and showed 99% similarity. We found in seq1 82, in seq2 82, seq3 83, seq4 82 nucleotide alterations involving 10 protein-coding genes and meaning 29 amino acid substitutions as well.
