Fig. 9

Boxplots of Ka/Ks between species. Ka/Ks values were obtained by aligning the CDS of genes of T. foenum-graecum with those of five plants (Trifolium pratense, Trifolium meduseum, Trifolium grandiflorum, Trifolium aureum, Medicago truncatula). The horizontal coordinates indicate the gene names and the vertical coordinates indicate the Ka/Ks values. In the box plots, the upper and lower edges of the rectangle indicate the upper and lower quartiles, the thick line inside the box indicates the median whereas the dots beyond the upper and lower edges of the box indicate outliers. Whiskers above and below the box indicate the range of Ka/Ks ratio values
