Abstract: Composition and methods for the modification of the secondary metabolic functions of glandular trichomes in plants, such as tobacco or Cannabis, that control the formation of terpenes that impart specific flavor and aroma characteristics to the plant leaves are provided. Enhanced terpene production and composition are achieved through targeted modification in the biochemical synthesis pathways for menthol and cis-abienol. This application provides novel nucleotide sequences encoding the enzymology for production of these terpenes in tobacco and Cannabis application to their use plants.
