Phylogenetic relationships of flavonoid synthesis genes with safflower, rice and Arabidopsis thaliana. The phylogenetic tree was constructed using MEGA 5.0 with the neighbor-joining method. The safflower flavonoid genes were divided into 8 families: C3H, C4H, OMT, LAD, HCT, CHI, CHS and F3H. According to the clustering results, we named the flavonoid biosynthesis genes in safflower
