The complete mtDNA genome of Erythroculter ilishaeformis: genome characterization and phylogenetic analysis

The complete mitochondrial genome sequence of the hybrid of Erythroculter ilishaeformis was first determined by a PCR-based sequencing method in this study. The mitochondrial was 16 624 bp in length, including 13 protein genes, two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes and one control region. All genes were encoded on the heavy strain except for ND6 and eight tRNA genes. Base composition of the heavy strain was A (30.09%), T (24.96%), C (27.67%), G (16.41%) and with A + T bias of 55.05%. All the genes in E. ilishaeformis were distributed on the H-strand, except for the ND6 subunit gene and nine tRNA genes which were encoded on the L-strand. The phylogenetic relationships of 14 Cyprinidae species were reconstructed based on the complete mtDNA sequences using the MEGA inference method.
