We performed a decapitation treatment on a pair of near isogenic lines differentiated at the D-locus to investigate the transcriptomic response to increased sugar accumulation, and we identified differentially expressed genes related to programmed cell death, as well as a bHLH093 homolog involved upstream of gibberellin signaling. In addition, we detected enriched motifs associated with ethylene response, which may indicate a role in programmed cell death, and an induction of the hexose transporter SWEET1A, which may suggest an increase in the apoplasmic unloading at sink tissues.
