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

Abstract

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.
