Evolutionary relationships among acyltransferase proteins in different plant species. The tree was obtained using peptide sequences from S. melongena (Eggplant), S. lycopersicum (Tomato), S. tuberosum (Potato), C. annuum (Pepper), P. axillaris (Petunia), and Vitis vinifera (Vitis). SmelAAT and other acyltransferases with known function from the literature (SlAT2, SmSpmHT, SlFdAT1/Sl3AT) are indicated next to the corresponding sequences. A previously described V. vinifera sequence (corresponding to Vv3AT) was included as the outgroup. A subtree comprising the 32 most distantly related sequences to SmelAAT was compressed for clarity. Only bootstrap values >50 are shown.
