Terpene Expression Regions
Terpene Expression Regions (TERs) refer to genetic loci and environmental zones where volatile secondary metabolites accumulate and differentiate across cannabis plant tissues. These regions are not single genes but rather clusters of genes involved in terpene biosynthesis, often found on different chromosomes and regulated by developmental and environmental signals. Breeders observe variable terpene profiles even within stabilized lines, reflecting both genetic potential and expression modulation. Understanding TERs helps explain why phenotypic variation in aroma and volatile composition persists across clones and seeds from the same cross.

Breeders working with terpene-forward selections examine tissue-specific expression patterns—glandular trichomes versus leaf volatiles—to stabilize desired aromatic profiles across generations. This trait family is central to pheno-hunting and selection programs targeting consistent secondary metabolite production.
