Abstract excerpt

Brassinosteroids are biosynthesized from campesterol via several cytochrome P450 (P450)-catalyzed oxidative reactions. We report the biochemical characterization of two brassinosteroid-biosynthetic P450s from rice: CYP90D2 and CYP90D3. A rice dwarf mutant, ebisu dwarf (d2), which contains a defective copy of CYP90D2, is known to be a brassinosteroid-deficient mutant, and CYP90D2 has been considered to act as a...
