Figure 5From: Molecular evolution accompanying functional divergence of duplicated genes along the plant starch biosynthesis pathwaySites under selection along the evolution of the three starch biosynthesis enzymes exhibiting functional specialization, SS, BE and DBE. A: Starch synthase gene family; B: Branching enzyme gene family (following D2); C: Debranching enzyme gene family. Sites are positioned on consensus sequences built for each gene family. Posterior probability (PP) of sites detected under positive selection in branch a (above the sequence) or b (beneath the sequence) are indicated: * for PP > 0.95, ** for PP > 0.99. Sites highlighted in dark grey in the be enzyme gene correspond to the catalytic domain described by Burton and collaborators [31].Back to article page
