Phylogenetic analyses of C. album UDP-glucosyltransferase (UGT) family members. The phylogenetic tree was constructed in the MEGA 6.0 program using the Neighbour-Joining method, and the bootstrap value was set to 1000. A total of 278 amino acid sequences of different plant UGTs were used, including 140 C. album UGTs, 122 Arabidopsis UGTs, four Prunus UGTs, three Z. mays UGTs, one Punica UGT and eight other UGTs that have been functionally characterized, including UGTs from Punica granatum, Quercus robur, F. × ananassa, V. vinifera, and C. sinensis. The outermost letters indicate different groups, including groups A–Q and the OG. Their information was shown in Table S1. Each group is highlighted in a different color.
