Phylogenetic tree showing A. glabripennis (color) and T. castaneum (black) UDP-glycosyltransferases (UGTs), reconstructed from amino acid sequences using ML inference (MLBS values <70 not shown). Each gene belonging to UGT352, UGT321, and UGT328 consists of four exons, with the long first exon (ca. 810 amino acids) followed by three short exons. Each member of UGT323, UGT324, and UGT325 is composed of four exons with the short first exon (ca. 200 amino acids) and the long second exon (ca. 800 amino acids) followed by two short exons. UGT312 and UGT353 (AglaUGT_63 and _64) consistently contain genes with five exons. Scaffold 72 is shown to illustrate the tandem arrangement typical of A. glabripennis UGTs.
