The complete F-type mitochondrial genome of Unio douglasiae is reported for the first time in this research. It is 15,767 bp in size and contains 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes. Except for COI, ND2, CYTB, ND1, ND6, ND4L, ATP8 with ATA start codon, and ND4 with ATT start codon, the remaining protein-coding genes initiate with the orthodox ATG start codon. There are 25 noncoding regions found throughout the mitogenome of Unio douglasiae, ranging in the size from 1 to 312 bp, the largest of which is between tRNA and ND2 (312 bp).
本研究首次报道了河蚬完整的F型线粒体基因组。其大小为15767bp,包含13个蛋白质编码基因、22个tRNA基因和2个rRNA基因。除COI、ND2、CYTB、ND1、ND6、ND4L、以ATA为起始密码子的ATP8以及以ATT为起始密码子的ND4外,其余蛋白质编码基因均以正统的ATG起始密码子起始。在河蚬的整个线粒体基因组中发现了25个非编码区,大小从1bp到312bp不等,其中最大的位于tRNA和ND2之间(312bp)。
