Unformatted text preview: mutant identified initially (in other words, was this mutant discovered in a targeted genetic screen for mutants that are defective in producing brassinosteroids)? 6. What was the initial discovery that led to the hypothesis that det2 mutant might be a steroid biosynthetic mutant? Explain an experiment that proved this hypothesis. 7. How were the bri1 ( brassinosteroid-insensitive 1 ) mutants discovered? What kind of protein does the Arabidopsis BRI1 gene encodes? 8. What is the main inhibitor protein in the brassinosteroid-signaling pathway? How does this negative regulator affect the plant steroid signaling?...
