Complete mitochondrial genome of Sinogastromyzon szechuanensis (Teleostei, Cypriniformes, Balitoridae) obtained using next-generation sequencing

Abstract

The complete mitogenome sequence of Sinogastromyzon szechuanensis was obtained using next generation sequencing and confirmed via overlap-PCR method. The genome was 16,565 bp in length and consisted of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 23 transfer RNA genes and 1 control region. The overall nucleotide composition of heavy strand was 30.38% A (5033), 16.62% G (2753), 25.25% T (4182) and 27.75 (4597), with a slight A–T skew (55.63%), which is most obvious in the D-loop and most transfer RNA genes. Mitochondrial genome analyses based on ML analyses yielded identical phylogenetic trees.
