Figure 4. Phylogenetic tree of DGAT1, DGAT2 and DGAT3 gene families reconstructed by the neighbor-joining (NJ) method.

Gene sequences other than peanut DGATs were shown by their nomenclatures found of www.phytozome.org, with the abbreviations. Colored branches indicated different groups of proteins. Red: DGAT2, blue: DGAT3, purple: DGAT1. Bootstrapping with 1,000 replicates was used to establish the confidence limits of the tree branches.
