The tomato DWARF enzyme catalyses C-6 oxidation in brassinosteroid biosynthesis

Bishop, Gerard J., Nomura, Takahito, Yokota, Takao, Harrison, Kate, Noguchi, Takahiro, Fujioka, Shozo, ...

Brassinosteroids (BRs) are steroidal plant hormones essential for normal plant growth and development. Mutants in the biosynthesis or perception of BRs are usually dwarf. The tomato Dwarf gene (D),...

BAS1: A gene regulating brassinosteroid levels and light responsiveness in Arabidopsis

Neff, Michael M., Nguyen, Serena M., Malancharuvil, Elizabeth J., Fujioka, Shozo, Noguchi, Takahiro, Seto, Hideharu, ...

The Arabidopsis bas1-D mutation suppresses the long hypocotyl phenotype caused by mutations in the photoreceptor phytochrome B (phyB). The adult phenotype of bas1-D phyB-4 double mutants mimics that...

The Arabidopsis dwarf1 Mutant Is Defective in the Conversion of 24-Methylenecholesterol to Campesterol in Brassinosteroid Biosynthesis1

Choe, Sunghwa, Dilkes, Brian P., Gregory, Brian D., Ross, Amanda S., Yuan, Heng, Noguchi, Takahiro, ...

Since the isolation and characterization of dwarf1-1 (dwf1-1) from a T-DNA insertion mutant population, phenotypically similar mutants, including deetiolated2 (det2), constitutive photomorphogenesis...

A Putative Role for the Tomato Genes DUMPY and CURL-3 in Brassinosteroid Biosynthesis and Response1

Koka, Chala V., Cerny, R. Eric, Gardner, Randy G., Noguchi, Takahiro, Fujioka, Shozo, Takatsuto, Suguru, ...

The dumpy (dpy) mutant of tomato (Lycopersicon esculentum Mill.) exhibits short stature, reduced axillary branching, and altered leaf morphology. Application of brassinolide and castasterone rescued...

Biosynthetic Pathways of Brassinolide in Arabidopsis1

Noguchi, Takahiro, Fujioka, Shozo, Choe, Sunghwa, Takatsuto, Suguru, Tax, Frans E., Yoshida, Shigeo, ...

Our previous studies on the endogenous brassinosteroids (BRs) in Arabidopsis have provided suggestive evidence for the operation of the early C6-oxidation and the late C6-oxidation pathways, leading...

Arabidopsis det2 Is Defective in the Conversion of (24R)-24-Methylcholest-4-En-3-One to (24R)-24-Methyl-5α-Cholestan-3-One in Brassinosteroid Biosynthesis1

Noguchi, Takahiro, Fujioka, Shozo, Takatsuto, Suguru, Sakurai, Akira, Yoshida, Shigeo, Li, Jianming, ...

Previously, we have shown that the Arabidopsis det2 (deetiolated2) mutant is defective in the biosynthesis of brassinosteroids (BR) and that DET2 (a steroid 5α-reductase) acts early in the proposed...

Brassinosteroid-Insensitive Dwarf Mutants of Arabidopsis Accumulate Brassinosteroids1

Noguchi, Takahiro, Fujioka, Shozo, Choe, Sunghwa, Takatsuto, Suguru, Yoshida, Shigeo, Yuan, Heng, ...

Seven dwarf mutants resembling brassinosteroid (BR)-biosynthetic dwarfs were isolated that did not respond significantly to the application of exogenous BRs. Genetic and molecular analyses revealed...

Loss of Function of a Rice brassinosteroid insensitive1 Homolog Prevents Internode Elongation and Bending of the Lamina Joint

Yamamuro, Chizuko, Ihara, Yoshihisa, Wu, Xiong, Noguchi, Takahiro, Fujioka, Shozo, Takatsuto, Suguru, ...

Brassinosteroids (BRs) are plant growth–promoting natural products required for plant growth and development. Physiological studies have demonstrated that exogenous BR, alone or in combination with...
