To obtain a selective marker gene for generation of transgenic trees, we cloned and sequenced the cDNA of UDP-N-acetylglucosamine : dolichyl-phosphate N-acetylglucosaminephosphotransferase (GPT) from Lombardy poplar (Populus nigra var. italica). Overexpression of GPT in budding yeast conferred tunicamycin tolerance. We succeeded in the generation of GPT-introduced transgenic poplars by using tunicamycin and a new binary vector, which contained the cDNA of GPT as a selective marker gene.
