Abstract excerpt
Brassinosteroids BRs)play important roles in plant growth and development.BRs modulate the phosphorylation status of two crucial transcription factors, BRI1 EMS SUPPRESSOR1 BES1)and BRASSINAZOLE RESISTANT1 (BZR1).Here we show that BES1 functions as a nucleocytoplasmic signal transmitter, and that its subcellular localization modulates the output intensity of the BR signal.BRASSINOSTEROID INSENSITIVE2 (BIN2)and...
