Complete F-type mitochondrial genome of Chinese freshwater mussel Lamprotula tortuosa.

Lamprotula tortuosa is the endemic species of freshwater pearl mussel in China. The complete F-type mitochondrial genome of L. tortuosa was first determined. This circle genome (15,722 bp in size) comprises 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, except for COI, CYTB, ND6, and ND4L, with TTG, ATT, ATT, and ATA start codon, respectively; the remaining protein-coding genes initiated with the orthodox ATG start codon. There were 25 noncoding regions found throughout the mitogenome of L. tortuosa, ranging in size from 1 to 241 bp, the largest of which is between ND5 and tRNA^Gln (241 bp), but is shorter than the control region sequences(about 280 bp) of freshwater mussels from Poland and South Korea.
