Phylogenetic analysis of UGT protein sequences in the Archaeplastida.

Unrooted cladogram of a maximum likelihood (ML) analysis of Archaeplastida UGT proteins conducted by PhyML 3.0 [50] using an estimated gamma distribution parameter, the LG_G+F model of amino acid substitution, and a Chi2-based approximate likelihood ratio (aLRT) test. Support values from the aLRT test for each clade are presented in parentheses. Protein sequences were aligned using MAFFT with the L-INS-I algorithm. UGT classes are indicated by pink highlighting and letters. Coloured dots indicate the presence of sequences from different species in each group. A. thaliana (yellow); O. sativa (dark green); S. moellendorffii (light blue); P. patens (light green); A. agrestis (dark purple); M. polymorpha (blue); K. nitens (light purple); C. reinhardtii (pink); C. merolae (maroon); C. paradoxa (orange). Confirmed NTSR genes or their A. thaliana homolog reported in Table 5 are indicated.
