Euonymus species from the Celastraceae family are considered as a source of unusual genes modifying the oil content and fatty acid composition of vegetable oils. Due to the possession of genes encoding enzyme diacylglycerol acetyltransferase (DAcT), Euonymus plants can synthesize and accumulate acetylated triacyglycerols. The gene from Euonymus europaeus (EeDAcT) encoding the DAcT was identified, isolated, characterized, and modified for cloning and genetic transformation of plants. This gene has a unique nucleotide sequence and amino acid composition, different from orthologous genes from other Euonymus species. Nucleotide sequence of original EeDAcT gene was modified, cloned into transformation vector, and introduced into tobacco plants. Overexpression of EeDAcT gene was confirmed, and transgenic host plants produced and accumulated acetylated triacylglycerols (TAGs) in immature seeds. Individual transgenic plants showed difference in amounts of synthesized acetylTAGs and also in fatty acid composition of acetylTAGs. |
