Fig. 1. Identified WGD events in leptosporangiates, as reported by the 1KP initiative (2019) (left) and by Huang et al. (2020) (right).

Ten of 14 WGDs in leptosporangiates from the 1KP initiative (2019) are denoted as (light) red stars. Four WGDs are not included because they were placed in lineages not studied by Huang et al. (2020). Ten out of ten WGD events from Huang et al. (2020) are denoted as (light) blue stars. WGD events found in the same lineages by both studies are in solid red and solid blue. The grey background highlights the core leptosporangiates in the two phylogenetic trees. The names for species with fully sequenced genomes are in bold. The green circles denote the WGDs in core leptosporangiates identified in this study.
