Sequence alignment and tree showing the relationship of
genes in Primulaceae. (A) Amino acid positions that are shaded are identical to PveGLO2. (B) The tree was rooted with the PI gene sequence from the kiwifruit draft genome (A. chinensis, ). Branch support values were calculated based on 1,000 neighbor-joining bootstrap replicates. Our labelling of GLO1 and GLO2 follows the convention established by Viaene et al. .
