A phylogenetic tree of IGT family genes in A. thaliana, A. hypogaea, A. duranensis, and A. ipaensis constructed using the maximum likelihood method; Overall, 13 IGTs from A. hypogaea (red stars), 7 IGTs from A. thaliana (light blue triangles), 7 IGTs from A. ipaensis (orange boxes), and 6 IGTs from A. duranensis (light green boxes) were clustered into three major classes, denoted by different colors. The bootstrap is displayed in orange circles.
