a Altitude across the Qinghai-Tibet plateau (top left), a vegetative individual (bottom left) and a reproductive individual (right) of noble rhubarb. b Overview of the two Rheum genomes, the tracks (moving inward) show: (I) chromosomes; (II) gene numbers (0–100); (III) GC content (0.25–0.45); (IV) TE density (0–100%); (V) Gypsy density (0–90%); (VI) Copia density (0–60%); and (VII) identified syntenic blocks, calculated using 500 kb sliding windows. c Phylogenetic tree of 16 species and dating of WGD events. Gains and losses of gene families in sub-branches are highlighted in orange and green, respectively. Red, green and blue stars indicate Polygonaceae-specific WGDs, other reported WGDs, and whole-genome triplication events, respectively. d Distribution of average synonymous substitutions (Ks) between syntenic blocks after evolutionary rate correction. e Dotplots of interspecific syntenic blocks among Vitis vinifera, Fagopyrum tataricum, and R. nobile.
