RT Journal Article T1 The male and female complete mitochondrial genomes of the threatened freshwater pearl mussel Margaritifera margaritifera (Linnaeus, 1758) (Bivalvia:Margaritiferidae) T2 Los genomas mitocondriales femenino y masculino completos de la náyade amenazada Margaritifera margaritifera (Linnaeus, 1758) A1 Froufe, Elsa A1 Amaro González, Rafaela María A1 Ondina Navarret, María Paz A1 Breton, Sophie A1 Guerra, Davide A1 Bolotov, Ivan N. A1 Vikhrev, Ilya A1 Gan, Han Ming A1 Gomes dos Santos, André K1 Doubly uniparental inheritance; mitogenome; Unionida K1 Doubly uniparental inheritance K1 Mitogenome K1 Unionida AB The complete mitogenomes of one (M-)ale (North America), one Hermaphroditic (Europe), and two(F-)emale (North America and Europe) individuals of the freshwater pearl mussel Margaritifera margaritifera were sequenced. The M-type and F-type (Female and Hermaphroditic) mitogenomes have 17,421 and 16,122 nucleotides, respectively. All with the same content: 13 protein-coding genes, 22 transfer RNA, two ribosomal RNA genes, and one sex-related ORF. The M-type is highly divergent (37.6% uncorrected p-distance) from the F-type mitogenomes. North American and European F-type mitogenomes exhibit low genetic divergence (68nt substitutions), and the Female and Hermaphroditic Europeanmitogenomes are almost identical, and matching sex-related ORFs.
