Expression divergence between duplicate genes derived from WGD, tandem (TD), proximal (PD), transposed (TRD), and dispersed (DSD) duplication in a C. reinhardtii, b P. patens, c S. moellendorffii, d P. abies, e A. trichopoda, f O. sativa, g N. nucifera, and h A. thaliana. The proportion of gene pairs conserved and divergent in expression, respectively, was indicated by different colors. i–k The expression divergence between duplicate genes derived from genome duplication events of different ages in model plants A. thaliana (eudicot) and O. sativa (monocot). l–n Expression divergence between duplicate genes in eudicot and monocot plants: l Zea mays, Sorghum bicolor, and Ananas comosus; n Camelina sativa, Brassica oleracea, and Vitis vinifera. j, m The phylogeny of different species and genome duplication or triplication events occurring in different branches were labeled. Significant differences (Fisher’s exact test): *P < 0.05, **P < 0.01, ***P < 0.001, n.s.P > 0.05
