A Genomic Approach to Study Anthocyanin Synthesis and Flower Pigmentation in Passionflowers

Figure 4

A Neighbor-joining phylogenetic tree of dihydroflavonol 4-reductase (DFR) amino acids sequences. Bootstrap values from 1,000 replicates were used to assess the robustness of the trees. Only bootstrap values above 75% are indicated at the nodes. Asn-type DFRs, Asp-type DFRs, and DFRs of neither Asn nor Asp-type are indicates in blue, red, and black, respectively [42]. Accession numbers for genes from other species are given in Supplementary data which are available online at doi:10.4061/2011/37157.
