The XY files: sex determination in hemp.

Hemp (Cannabis sativa) is a multipurpose crop that is used for thousands of different applications. Unlike most other plants, hemp is primarily dioecious, with individual male and female plants. The basis of the sex determination in hemp is a genetic XY sex chromosome system, but the molecular details of this system remain unresolved. Some hemp lines are even monoecious, with male and female flowers on the same individual, illustrating the flexibility of the sex determination in hemp. Understanding the sex determination system of hemp is of considerable significance for different agricultural and industrial applications. For example, only female inflorescences produce valuable secondary compounds and are thus preferred for phytocannabinoid production. For fiber production, male plants are preferred because their level of lignification is usually lower.  We aim to conduct a detailed morphological and genetic analysis to better understand sex determination in hemp. This will include detailed studies of the different stages of hemp flower development as well as transcriptomics analyses of hemp male and female flowers. Our goal is to better understand the molecular genetic basis as well as the morphological details of sex determination in hemp.
