Fig. 2: Evidence for WGD in I. taiwanensis.
From: Underwater CAM photosynthesis elucidated by Isoetes genome
a Ks plot showing a peak centered on 1.8 corresponding to the ISTEβ event. b Hypothesized WGD events that were tested (colored rectangles) in our WhALE analysis are shown on a phylogeny. c I. taiwanensis’ posterior distribution of gene retention rates (q) falls between that of A. filiculoides and P. patens, both are known to have at least one WGD. This provides additional support for the ISTEβ event. Conversely, the gene retention rate is close to zero for M. polymorpha, consistent with its lack of WGD. Source data are provided as a Source Data file.
