Additional file 5: Table S4. of Genome-wide analysis of the TPX2 family proteins in Eucalyptus grandis

The Ka/Ks ratios and Evolutionary selection of paralogous TPX2 family proteins. Ks: number of synonymous substitutions per synonymous site; Ka: number of nonsynonymous substitutions per nonsynonymous site. When Ka/Ks = 1, neutral evolution; Ka/Ks < 1, purifying selection; Ka/Ks > 1, diversifying selection. Genes in duplicated pairs are in tandem duplication (Tandem), in homeologous chromosomes (Homeologous) or were simply paralogous. (XLSX 11 kb)
