Abstract
In this study, the complete mitochondrianl genome of Procypris merus was sequenced. It was determined to be 16,581 bp and included 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes and 1 non-coding region (D-loop). The descending order of the base composition on heavy strand was 31.91% A, 24.95% T, 27.39% C, 15.75% G, which is similar to other cyprinid fish mitochondrial genomes. All protein-coding genes had ATG as the start codon but the stop codons have three types. Night genes end with TAA or TAG, and COII, ND4, ND6 and Cytb genes terminate with an incomplete – –T. The complete mitochondrial genome may provide important DNA molecular data for further phylogenetic analyses for higher taxa of Cyprinidae.
