11389832 | Kang JG, Yun J, Kim DH, Chung KS, Fujioka S, Kim JI, Dae HW, Yoshida S, Takatsuto S, Song PS, Park CM: Light and brassinosteroid signals are integrated via a dark-induced small G protein in etiolated seedling growth. Cell. 2001 Jun 1;105(5):625-36. Here, we demonstrate that a dark-induced small G protein, pea Pra2, regulates a variant cytochrome P450 that catalyzes C-2 hydroxylation in brassinosteroid biosynthesis. Transgenic plants with reduced Pra2 exhibit a dark-specific dwarfism, which is completely rescued by exogenous brassinolide. |

17693126 | Bishop GJ: Refining the plant steroid hormone biosynthesis pathway. Trends Plant Sci. 2007 Sep;12(9):377-80. Epub 2007 Aug 10. Many of the biochemical conversions in plant steroid hormone biosynthesis are catalysed by cytochrome P450 enzymes (CYPs or P450s). A recent paper by Toshiyuki Ohnishi et al. (2006) indicates the role of CYP90C1 and CYP90D1 in the synthesis of the most bioactive plant steroid hormone, brassinolide. |

9990098 | Bishop GJ, Nomura T, Yokota T, Harrison K, Noguchi T, Fujioka S, Takatsuto S, Jones JD, Kamiya Y: The tomato DWARF enzyme catalyses C-6 oxidation in brassinosteroid biosynthesis. Proc Natl Acad Sci U S A. 1999 Feb 16;96(4):1761-6. The tomato Dwarf gene (D), which was predicted to encode a cytochrome P450 enzyme (P450) with homology to other P450s involved in BR biosynthesis, was cloned previously. Here, we show that DWARF catalyses the C-6 oxidation of 6-deoxocastasterone (6-deoxoCS) to castasterone (CS), the immediate precursor of brassinolide. |
