Fig. 4From: Characterizing glycosyltransferases by a combination of sequencing platforms applied to the leaf tissues of Stevia rebaudianaPhylogenetic analysis of the S. rebaudiana UGT superfamily shows 14 distinct groups, each with a bootstrap support greater than 90% in distance analysis excluding group I (66% bootstrap). The tree shown was derived by neighbour-joining distance analysis of the full-length amino acid sequence described in Additional file 6. Distance bootstrap analyses consisted of 1000 replicates. Bootstrap values are listed as percentages of the replications, where values over 50% are indicated above the nodesBack to article page
