Phylogeny of the ADP-Glucose transporter (AGT) and related transporters in plants, PANT1 and PANT2. Paralogs are identified by species name. Phylogeny is rooted with Physcomitrella patens. The scale is 0.1 substitutions per site. Nodes with bootstrap values lower than 90% were aggregated into rakes. Black circles indicate duplication events. Branch a emerging from duplication D1 and leading to the agt clade was tested for deviation from non-neutral evolution. Corresponding outgroup sequences used to infer ancestral states are followed by duplication name in square brackets.
