Comments See Nystedt et al., 2013 PMID 23698360 p.580 right column 2nd paragraph: "However, a population dynamics model that takes into account both small- and large-scale modes of gene duplication (ref 20) suggested the presence of a small peak (around Ks of 1.1), which, considering the slow substitution rate of conifers, might represent the ancient WGD [Whole genome duplication] predating the divergence of angiosperms and gymnosperms (350 Myr ago (ref 21))."
