“…In contrast, Williams et al () recognized both species based on their morphological distinctiveness and the fact that molecular evidence for synonymy was based on only one marker (ND1) from a single specimen. However, ND1 has been shown to be a highly representative marker of overall mtDNA evolution in unionoid mussels (Fonseca, Lopes‐Lima, Eackles, King, & Froufe, ). In addition, divergence between C. asperata and C. kieneriana sequences was very low.…”

Freshwater mussels (Bivalvia, Unionidae) have suffered strong declines over the last century. High morphological plasticity of Unionidae causes disturbances in their systematics and taxonomy, hampering conservation efforts. Species that have historically been placed under the North American genus Quadrula have suffered from numerous taxonomic and species delineation problems since its inception. Four genera are presently recognized within Quadrula sensu lato, that is, Cyclonaias, Quadrula, Theliderma and Tritogonia, but their phylogenetic basis remains incompletely tested. In the present study, we reconstructed several two-marker (mtDNA cytochrome c oxidase subunit I-COI and NADH dehydrogenase subunit 1-ND1) phylogenies with newly collected specimens and all previously available sequences covering most species within this group. We then delineated the species within the group using an integrative approach with the application of molecular statistical methods, morphometric (Fourier Shape) analyses and geographic distribution data.Four clades corresponding to these genera were consistently recovered in all phylogenies. To validate the generic status of these clades, molecular analyses were complemented with morphological, anatomical and ecological data compiled from the literature. Several revisions are here proposed to the current systematics and taxonomy of these genera, including the synonymization of Cyclonaias asperata under Cyclonaias kieneriana; the inclusion of Quadrula apiculata and Quadrula rumphiana under Quadrula quadrula; the placement of Quadrula nobilis under Tritogonia; and finally the separation of the Mobile River basin populations of Theliderma metanevra as a new species, that is, Theliderma johnsoni n. sp. The conservation implications of the proposed changes are then discussed. 314 | LOPES-LIMA Et AL.

“…This is in contrast to the vast majority of animal taxa, which inherit their mtDNA exclusively through the maternal lineage and thus exhibit only F-type mtDNA. In Unionoidea males, M-type mtDNA is restricted to the gonadal tissue inherited from the paternal lineage, and F-type mtDNA is present in all somatic tissues transmitted from the maternal lineage and also in female gonadal tissue (Breton et al 2009;Froufe et al 2016;Fonseca et al 2016;Lopes-Lima et al 2017b).…”

“…In recent decades, complete mitochondrial genome sequences have been published for a wide range of taxa, enabling reconstruction of shallow and deep phylogenies in both vertebrates and invertebrates (e.g., Jacobsen et al 2014;Liu et al 2016). However, the number of available mitogenomes for Unionida is low, particularly for M-type genomes (Froufe et al 2016;Fonseca et al 2016;Lopes-Lima et al 2017b;Huang et al 2019). A further shortcoming is that published mitogenomes are restricted to only a few higher Unionida taxa, with no mitogenomes being available for several families and subfamilies.…”

Mesozoic mitogenome rearrangements and freshwater mussel (Bivalvia: Unionoidea) macroevolution

Using a new fossil-calibrated mitogenome-based approach, we identified macroevolutionary shifts in mitochondrial gene order among the freshwater mussels (Unionoidea). We show that the early Mesozoic divergence of the two Unionoidea clades, Margaritiferidae and Unionidae, was accompanied by a synchronous split in the gene arrangement in the female mitogenome (i.e., gene orders MF1 and UF1). Our results suggest that this macroevolutionary jump was completed within a relatively short time interval (95% HPD 201-226 Ma) that coincided with the Triassic-Jurassic mass extinction. Both gene orders have persisted within these clades for~200 Ma. The monophyly of the so-called "problematic" Gonideinae taxa was supported by all the inferred phylogenies in this study using, for the first time, the M-and F-type mitogenomes either singly or combined. Within Gonideinae, two additional splits in the gene order (UF1 to UF2, UF2 to UF3) occurred in the Mesozoic and have persisted for~150 and~100 Ma, respectively. Finally, the mitogenomic results suggest ancient connections between freshwater basins of East Asia and Europe near the Cretaceous-Paleogene boundary, probably via a continuous paleo-river system or along the Tethys coastal line, which are well supported by at least three independent but almost synchronous divergence events.

“…The M-type and F-type mitochondrial lineages show high levels of divergence within species of Unionida freshwater mussels and even distinct gene order arrangements (Fonseca et al 2016;Froufe et al 2016;Guerra et al 2017). The Margaritiferidae also exhibit a unique M-type and F-type gene order (Lopes-Lima, Fonseca, et al 2017).…”

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 (68 nt substitutions), and the Female and Hermaphroditic European mitogenomes are almost identical, and matching sex-related ORFs.
