Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

open access: yesNew Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

A chemotaxonomic analysis of cannabinoid variation in Cannabis (Cannabaceae) [PDF]

open access: yesAmerican Journal of Botany, 2004
Cannabinoids are important chemotaxonomic markers unique to Cannabis. Previous studies show that a plant's dry‐weight ratio of Δ9‐tetrahydrocannabinol (THC) to cannabidiol (CBD) can be assigned to one of three chemotypes and that alleles BD and BT encode alloenzymes that catalyze the conversion of cannabigerol to CBD and THC, respectively.

Genetic architecture of phenological, morphological, and phytochemical traits in Cannabis landraces

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Despite its long history of cultivation and diverse applications, Cannabis sativa remains underexplored at the genomic level, particularly in landrace populations that harbor untapped genetic diversity. In this study, we investigated the genetic architecture of 145 Iranian cannabis landrace accessions, including both male and female plants ...
