Taxon-rich transcriptomics supports higher-level phylogeny and major evolutionary trends in Foraminifera

We analyzed transcriptomic data from 28 Foraminiferal species, adding 19 new species to the previously published dataset, including members of the strongly under-represented class Monothalamea. A phylogenomic reconstruction of Rhizaria, rooted with alveolates and stramenopiles, based on 199 genes and 68 species supports the monophyly of Foraminifera and their sister relationship to Polycystinea.
