Assay Methods for BR Biosynthesis Inhibitors

B L is synthesized from campesterol via either early or late C-6 oxidation pathways that include cytochrome P450 monooxygeneses. 

Other plant hormones, such as auxins and GAs. Finally, selected compounds were assayed using a cress hypocotyl elongation test. It has been demonstrated that cress is very sensitive to an internal deficiency of BRs and is therefore a useful species for evaluating BR biosynthesis inhibitors [7-8],
