From: Rapid turnover of life-cycle-related genes in the brown algae
Evolution of generation-biased genes. a Evolutionary rates measured as dN/dS between species pairs (Ectocarpus sp./S. lomentaria, M. pyrifera/S. japonica) for unbiased, gametophyte-biased, and sporophyte-biased genes in the four brown algal species. b Gene expression divergence measured as Euclidean distances for unbiased, gametophyte-biased, and sporophyte-biased genes in each of the four brown algal species. Different letters above the plots indicate significant differences (pairwise Wilcoxon test; p value < 0.05)
