title: Complete F-type mitochondrial genome of Chinese freshwater mussels Lamprotula gottschei.
abstract: Lamprotula gottschei (Von Martens, 1894) is one of the freshwater pearl mussels which have great meaning on economy in China. The complete F-type mitochondrial genome of L. gottschei was firstly determined. This circle genome (15,915 bp in size) comprises 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, except for COI, CYTB, ND4, ND6 and ND4L, with ATA start codon, the remaining protein-coding genes initiated with the orthodox ATG start codon. There were 25 non-coding regions found throughout the mitogenome of L. gottschei, ranging in size from 1 to 305 bp, the largest of which is between ND2 and tRNA(Gln) (305 bp), and is longer than the control region sequences (about 280 bp) of freshwater mussels from Poland and South Korea. Strictly maternal inheritance (SMI) of mitochondrial DNA (mtDNA) is the standard rule in nearly all anisogamic organisms (SMI), (Roze et al., 2005; White et al., 2008). However, bivalves of the marine family Mytilidae and Veneroida as well as the freshwater family Unionidae possess two independently inheritance mode of mitochondrial DNA (mtDNA) (Boyle & Etter, 2013), which involves maternal (F) and paternal (M) transmission routes concomitant with highly divergent gender-associated mtDNA genomes. This system of mtDNA transmission was called doubly uniparental inheritance (DUI) (Zouros, 2000).
