title: Complete male mitochondrial genome of Anodonta anatina (Mollusca: Unionidae).
abstract: Anodonta anatina is a freshwater mussel of the family Unionidae. These mussels have a unique mitochondria inheritance system named doubly uniparental inheritance (DUI). Under DUI males have two, potentially very divergent mitochondrial genomes: F-type inherited from mother and M-type inherited from father. F-type is present in soma whereas M-type is present in gonadal tissues and sperm. Here we report two M-type sequences of complete mitochondrial genomes from Anodonta anatina. They are 16,906 bp long and their sequences are similar (0.1% divergence). The genome organization is identical to the other Unionidean M-type genomes published to date. There are 38 genes, including the recently described M-type specific M ORF. The presence of tRNA-like repeat in one of the noncoding regions, suggests that the control region is located in this area. Nucleotide composition is quite extreme, with AT content (66.2%) higher than in any other of the six published Unionidean M genomes.
