Here we describe the generation of potato plants that constitutively overexpressed, UDP-N-acetylglucosamine: dolichol phosphate-N-acetylglucosamine- phosphotransferase (GPT). Such transgenic plants can be formed in a medium with tunicamycin at 9:8 ± 0:28% efficiency, similar to the 9:4 ± 1:10 for the bialaphos resistance gene (Bar) gene. This study indicated that GPT transformation was very stable with high reproducibility, and that growth and tuber production in the GPT-transformed plants were stronger than in the wild-type plants.
