Fig. 3: Comparative genomic analyses of Chinese wild rice genome.

a Distribution of gene copy number in Chinese wild rice and nine other species. b Venn diagram of shared orthologous gene families in Chinese wild rice and other four related gramineous species (Brachypodium distachyon, Leersia perrieri, Oryza brachyantha, and O. sativa). c Phylogenetic tree of Chinese wild rice and nine other species. “+” represents the number of gene families expanded on the node and “-” represents the number of gene families contracted on the node. The pie chart shows the proportion of the corresponding branch contraction and expansion gene families. d, KEGG enrichment analyses for the expanded genes in the Chinese wild rice genome. e Ks distribution in Chinese wild rice and other representative species.
