Proper control of the floral transition is critical for reproductive success in flowering plants. In Arabidopsis, FLOWERING LOCUS C (FLC) is a floral repressor upon which multiple floral regulatory pathways converge. Mutations in PHOTOPERIOD-INDEPENDENT EARLY FLOWERING1 (PIE1) suppress the FLC-media...
