Transcriptomic analysis of CDL-gated photoperiodic flowering mechanisms in cannabis and their responsiveness to R: FR ratios in controlled environment agriculture

Abstract While discrete regulatory mechanisms have been identified, a unified model for the transcriptional activation of photoperiodic flowering in short-day (SD) plants has not been delineated. Although the GIGANTEA-CONSTANS-FLOWERING LOCUS T (GI-CO-FT) pathway appears to be highly conserved, each species may differ in its blueprint for activation of FT and floral meristem identity. In cannabis, an SD plant, PSEUDO-RESPONSE-REGULATOR 37 (PRR37) has a causal effect in determining photoperiod sensitivity. This study identifies a network of WITH NO LYSINE (K) kinases
