(2019) The male and female complete mitochondrial genomes of the threatened freshwater pearl mussel Margaritifera margaritifera (Linnaeus, 1758) (Bivalvia: Margaritiferidae), Mitochondrial DNA B Part B, 4: 1417–20http://hdl.handle.net/10347/31903The 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.eng© 2019 The Author(s).
