Phylogenetic tree of ADP-Glc PPases from oxygenic photosynthetic organisms. The tree is clearly divided into three major branches corresponding to enzymes from cyanobacteria (blue) and small and large subunits from green algae and plants. The small subunits are further divided into five branches: green algae (GAS, green), S. moellendorffii (SmoS, orange); dicots (violet); and monocots (two branches, red). The large subunits are divided into six branches: green algae (GAL, green); S. moellendorffii (SmoL, orange); and four groups (I-IV) from dicots and monocots (yellow). Numbers correspond to the bootstrap values for the indicated branches.
