Title

Other claims from this paper (8)
- Intervention effect Auxin stimulated brassinosteroid biosynthesis.
- Intervention effect GUS activity increased beginning at 10 nm auxin.
- Intervention effect GUS activity rose noticeably after 1 h of auxin treatment.
- Mechanism Auxin induction required auxin-signaling pathways.
- Mechanism Auxin induction did not require brassinosteroids.
- Intervention effect Auxin inhibited BZR1 binding to the DWF4 promoter.
- Intervention effect Auxin-responsive genes were not properly regulated when brassinosteroid synthesis was disrupted by brassinazole.
- Mechanism The authors infer some auxin growth promotion relies on synthesized brassinosteroids.
