Data from: Unioverse: a phylogenomic resource for reconstructing the evolution of freshwater mussels (Bivalvia, Unionoida)

Freshwater mussels (order Unionoida) are a diverse radiation of parasitic
bivalves that require temporary larval encystment on vertebrate hosts to
complete metamorphosis to their free-living phase. The freshwater
mussel-fish symbiosis represents a useful relationship for understanding
eco-evolutionary dynamics in freshwater ecosystems but the practicality of
this promising model system is undermined by the absence of a stable
freshwater mussel phylogeny. Inadequate character sampling is the primary
analytical impediment obfuscating a coherent phylogeny of freshwater
mussels, specifically the lack of nuclear molecular markers appropriate
for reconstructing supraspecific relationships and testing
macroevolutionary hypotheses. The objective of this study is to develop a
phylogenomic resource, specifically an anchored hybrid enrichment probe
set, capable of capturing hundreds of molecular markers from taxa
distributed across the entirety of freshwater mussel biodiversity. Our
freshwater mussel specific anchored hybrid enrichment probe set, called
Unioverse, successfully captures hundreds of nuclear protein-coding loci
from all major lineages of the Unionoida and will facilitate more
data-rich and taxonomically inclusive reconstructions of freshwater mussel
evolution. We demonstrate the utility of this resource at three disparate
evolutionary scales by estimating a backbone phylogeny of the Bivalvia
with a focus on the order Unionoida, reconstructing the subfamily-level
relationships of the Unionidae, and recovering the systematic position of
the phylogenetically unstable genus Plectomerus.
