Fig. 4From: Evolution and expression of the fructokinase gene family in Saccharum The Ka/Ks of SsFRK haplotypes and SsFRK-SbFRK. The lower value of Ka/Ks is indicated by stars. The blue color indicates the Ka/Ks of gene pair allele comparisons, orange color indicates the Ka/Ks of orthologs genes between sorghum and S. spontaneum Back to article page
