Scenarios proposed for the evolution of DGAT1 and DGAT2 in eukaryotes. The proposed evolutionary relationships between DGAT1 and DGAT2 family members are as follows: DGAT1 and DGAT2 have evolved asymmetrically since the eukaryotic emergence and underwent convergent evolution likely due to the importance of TAGs for all eukaryotic organisms.
