    Abstract: A non-naturally occurring or transgenic Nicotiana tabacum plant cell encompassing a heterologous polynucleotide that encodes arginine decarboxylase (ADC) and a method for producing such a cell are provided. Transgenic Nicotiana tabacum plants, plant parts, and plant tissues including these cells and plant materials and biomass produced by these cells and plants cells forming such a plant are provided. Materials produced by this plant, including plant leaves, flowers, seeds, extracts, and other plant biomass obtained from this plant including materials that have altered alkaloid levels are disclosed. Also provided are smoking articles including various tobacco products containing these materials.
