Tissue Specific Biosynthesis

Tissue-specific biosynthesis refers to the differential production of metabolites—including cannabinoids, terpenes, and flavonoids—in different plant tissues such as trichomes, leaves, flowers, or stems. Cannabis produces most of its secondary metabolites in glandular trichomes on floral bracts and leaves, but the biochemical pathways active in root tissue, vascular bundles, and leaf mesophyll differ significantly. Understanding where and when specific compounds are manufactured is central to modern cannabis breeding and extraction strategy. This classification helps breeders identify genetic factors controlling metabolite distribution and accumulation patterns across plant organs.

Breeders working with tissue-specific biosynthesis traits focus on enhancing trichome density and metabolite concentration in target tissues while minimizing production in non-target areas. Selecting for robust expression of biosynthetic enzymes in floral tissue allows more efficient cannabinoid and terpene accumulation, directly influencing harvest quality and extraction yield without requiring c
