The two categories at left were compared for nonsynonymous rate differences (rN), synonymous rate differences (rS) or rate ratio (ω) differences. "Photo." refers to photosynthetic branches, "nonphoto." refers to nonphotosynthetic branches, "OEC" refers to Orobanche, Epifagus and Cistanche branches, and "HHB" refers to Harveya, Hyobanche and Boschniakia branches.
