Identification of genes associated with sex expression and sex determination in hemp (Cannabis sativa L.)

Abstract Dioecy in flowering plants has evolved independently many times, and thus the genetic mechanisms underlying sex determination are diverse. In hemp (Cannabis sativa), sex is controlled by a pair of sex chromosomes (XX for females and XY for males). In an attempt to understand the molecular mechanism responsible for sex expression in hemp plants, we carried out RNA sequencing of male and female plants at different developmental stages. Using a pipeline involving differential gene expression analysis and weighted gene
