The Structure of the Chemotype Determining Locus in Cannabis sativa

Plant Direct, Volume 10, Issue 5, May 2026.
ABSTRACT The chemical phenotype (chemotype) of Cannabis sativa is defined by the ratio of cannabidiolic acid (CBDA) to Δ9‐tetrahydrocannabinolic acid (THCA). Although the Mendelian segregation of these traits suggests a single‐locus biallelic system, recent sequencing and phylogenetic evidence indicate they are encoded by two distinct, tightly linked ...
