Ks distributions suggest possible genome duplications in basal angiosperms, and no evidence for genome duplication events in Amborella and some gymnosperm species. (A) Ks distribution in Amborella, a basal-most angiosperm. No significant large-scale duplication is detected. (B) Three distinct components in the Ks distribution for Nuphar, also a basal-most angiosperm, suggest at least two large-scale genome duplications. (C) Ks distribution for putative orthologs between Amborella and Nuphar. (D) Pinus taeda (loblolly pine) paralogous pairs follow the null model (see Methods). (E) Ks distribution for paralogs in a gymnosperm, Welwitschia.
