Phylogenetic tree derived from amino acid sequences of UGT78 genes in both monocots and eudicots. The GenBank accession numbers of previously reported F3GT genes are as follows: petunia PhF3GT1b-2 (Q9SBQ8) and PhF3GT1b-1 (BAA89008); potato StF3GT1b-1 (AAX63403) and StF3GT1b-2 (AEN83502); tobacco NtF3GT1b-1 (BAM37965) and NtF3GT1b-2 (BAM37964); Solanum melongena SmF3GT1b (Q43641); Rosa × hybrida RhF3GT1b (BAF80946), RhF3GT1a-1 (BAF80947), RhF3GT1a-2 (BAK09602), and RhF3GT1a-3 (BAE72453); and Hordeum vulgare HvF3GTa (P14726). The genome sequences of grapevine, poplar, castor bean, cassava, M. truncatula, soybean, common bean, cucumber, papaya, E. globulus, Arabidopsis, T. halophila, C. rubella, B. rapa, tomato, potato, rice, maize, sorghum, citrus, apple, and strawberry were searched for UGT78 homologs through the Phytozome version 5.0 database (http://www.phytozome.net). The peach UGT78 genes are highlighted in light gray. [See online article for color version of this figure.]
