Fig. 5: Fractionation of the synteny blocks in W. australiana.

a Synteny blocks were plotted on the chromosomes of O. sativa. The x-axis shows chromosomal positions and the y-axis shows the mean Ks values between W. australiana and O. sativa (left panel) and between S. polyrhiza and O. sativa (right panel). b GO enrichment analysis of the gene set from partially fractionated synteny blocks (top panel) and from missing synteny blocks (bottom panel). c Kernel density estimation plot of mean Ks values of intra-genome synteny blocks. The red vertical lines indicate ancient WGD peaks with the Ks values shown.
