However, limitations in the availability of bi-parental markers for ferns Low-copy markers have greatly limited phylogenetic investigation of polyploidy in this group. With a large number of allopolyploid PacBio species, the genus Botrychium is a classic example in ferns where recurrent polyploidy is postulated to have Polyploid network driven frequent speciation events. Here, we use PacBio sequencing and the PURC bioinformatics pipeline to PURC capture all homeologous
