The F-type complete mitochondrial genome of Arconaia lanceolata

In this study, complete nucleotide sequence of the F-type mitochondrial genome of Arconaia lanceolata (Bivalvia: Unioninae), the endemic species of freshwater pearl mussel in China, was first determined. The complete mitochondrial genome of Arconaia lanceolata is 15,782bp in size, and encodes 35 genes, including 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs. Those genes are similar to most species of Unioninae in order, structure and composition. In the 13 protein-coding genes, ND2, Cytb, ND1 and ND6 are located in the light chain while the rest on the heavy chain. Also, COXI, Cytb, ND1, ND6 and ND4L with ATA as start codon, the remaining protein-coding genes initiated with the orthodox ATG as start codon. There are 28 non-coding regions in the mitochondrial genome of A. lanceolata, the largest is of 345bp in length, located between ND5 and tRNA(Gln) gene.
