Figure S1. The response of gibberellin is reduced when brassinosteroid levels are low.

Figure S2. Loss of repressor function suppresses the DWF4ox long hypocotyl phenotype.

Figure S3. Brassinosteroids increase DELLA abundance.

Figure S4. Brassinosteroid treatment does not have large effects on repressor or SLY1 gene expression.

Figure S5. Brassinosteroids increase DELLA abundance similarly throughout the day.

Figure S6. Induction of DELLA target gene expression by brassinosteroids is reduced in seedlings with reduced DELLA function.

Figure S7. Loss of PIF or HY5 function has opposite effects on seedling height.

Figure S8. DWF4ox seedlings have intact brassinosteroid response elements.
