Phylogenetic relationships of wheat CCR and COMT genes with the homologs from other species. Phylogenetic trees of CCR (a) and COMT (b) were generated based on nucleic acid sequence similarity of the wheat genes with 34 CCR and 23 COMT genes, respectively, of other monocot and dicot species identified from the NCBI nucleotide database [39] using MEGA program [41], and the trees were inferred using Maximum Likelihood method based on the Tamura-nei model. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test of 500 replicates is shown next to the branches. ●, wheat candidate gene; ▲, genes from dicot species other than Arabidopsis; *, wheat sequence used for the analysis
