In vivo inhibition of polyamine biosynthesis and growth in tobacco ovary tissues

, : In vivo inhibition of polyamine biosynthesis and growth in tobacco ovary tissues. Plant & Cell Physiology 26(8): 1519-1526

Post-fertilization growth of tobacco ovary tissues treated with inhibitors of polyamine (PA) biosynthesis was examined in relation to endogenous PA titers and the activities of arginine decarboxylase (ADC) and ornithine decarboxylase (ODC). DL- alpha -Difluoromethylornithine (DFMO) and DL- alpha -difluoromethylarginine (DFMA), specific irreversible inhibitors of ODC and ADC in vitro, were used to modulate PA biosynthesis in excised flowers.
