Data from: Frequent allopolyploidy with distant progenitors in the moss genera Physcomitrium and Entosthodon (Funariaceae) identified via subgenome phasing of targeted nuclear genes

Polyploids represent a new frontier in species discovery among
embryophytes. Within mosses, polyploid discovery is challenged by low
morphological complexity. The rapid expansion of sub-genome sequencing
approaches in addition to computational approaches to identifying whole
genome duplication using allelic variation among nuclear markers has
allowed for increased polyploid discovery among mosses. We confirm the
intergeneric hybrid nature of E. hungaricus, and the allopolyploid origin
of P. eurystomum and of one population of P. collenchymatum. We also
reveal that hybridization gave rise to P. immersum, as well as to yet
unrecognized lineages sharing the phenotype of P. pyriforme, P. sphaericum
and P. collenchymatum. Our findings and methods demonstrate the utility of
a novel approach to allele phasing and subgenome assignment, called
homologizer, when working with polyploid genomes, and its value in
identifying progenitor species using target capture data.
