Finding Evidenee for Whole Genome Duplications: A Reappraisal

Dear Editor, Recently, Ren et al. reported an extensive analysis of the incidence of whole genome duplications (WGDs) throughout the evolutionary history of extant angiosperms (Ren et al., 2018). Examining a wealth of genomic data (36 complete genomes and 69 transcriptomic datasets) using commonly applied methods, they detected and located 55 WGDs throughout the an giosperm phylogeny.
