Brassinosteroids 111-127 Cytochrome P450 superfamily protein Arabidopsis thaliana 18-24 16407451-2 2006 Arabidopsis (Arabidopsis thaliana) DWARF4 (DWF4) catalyzes a flux-determining step in the BR biosynthetic pathways. Brassinosteroids 90-92 Cytochrome P450 superfamily protein Arabidopsis thaliana 35-41 16407451-2 2006 Arabidopsis (Arabidopsis thaliana) DWARF4 (DWF4) catalyzes a flux-determining step in the BR biosynthetic pathways. Brassinosteroids 90-92 Cytochrome P450 superfamily protein Arabidopsis thaliana 43-47 16407451-3 2006 Thus, it is hypothesized that the tissues of DWF4 expression may represent the sites of BR biosynthesis in Arabidopsis. Brassinosteroids 88-90 Cytochrome P450 superfamily protein Arabidopsis thaliana 45-49 16407451-8 2006 DWF4:GUS activity was increased by treatment with brassinazole, a BR biosynthetic inhibitor, and decreased by exogenous application of bioactive BRs. Brassinosteroids 66-68 Cytochrome P450 superfamily protein Arabidopsis thaliana 0-4 16407451-11 2006 Thus, it is likely that the DWF4 promoter serves as a focal point in maintaining homeostasis of endogenous bioactive BR pools in specific tissues of Arabidopsis.
