Journal ArticleDOI
Plant foods and herbal sources of resveratrol.
TL;DR: For people who do not consume alcohol, Itadori tea may be a suitable substitute for red wine and there is also a need for more information on the absorption and in vivo biomedical actions of free and conjugated resveratrol.
Journal ArticleDOI
Biosynthesis and Metabolism of Brassinosteroids
Shozo Fujioka,Takao Yokota +1 more
TL;DR: In this paper, a detailed study of the biosynthesis of brassinolide, a C28 BR, revealed that two parallel routes, the early and late C-6 oxidation pathways, are connected at multiple steps and also are linked to the early C-22 oxidation pathway.
Journal ArticleDOI
Metabolite Profiling of Hydroxycinnamate Derivatives in Plasma and Urine after the Ingestion of Coffee by Humans: Identification of Biomarkers of Coffee Consumption
Angelique Stalmach,William Mullen,Denis Barron,Kenichi Uchida,Takao Yokota,Christophe Cavin,Heike Steiling,Gary Williamson,Gary Williamson,Alan Crozier +9 more
TL;DR: Urinary dihydrocaffeic acid-3-O-sulfate and feruloylglycine are potentially very sensitive biomarkers for the consumption of relatively small amounts of coffee, indicating absorption in the large intestine and the probable involvement of catabolism by colonic bacteria.
Journal ArticleDOI
The tomato DWARF enzyme catalyses C-6 oxidation in brassinosteroid biosynthesis
Gerard J. Bishop,Takahito Nomura,Takao Yokota,Kate Harrison,Takahiro Noguchi,Shozo Fujioka,Suguru Takatsuto,Jonathan D. G. Jones,Yuji Kamiya +8 more
TL;DR: Data show that DWARF is involved in the C-6 oxidation of 6-deoxoCS to CS, the immediate precursor of brassinolide in BR biosynthesis, and the intermediate 6alpha-hydroxycastasterone was identified, indicating that DwarF catalyzes two steps inBR biosynthesis.
Journal ArticleDOI
The Arabidopsis deetiolated2 mutant is blocked early in brassinosteroid biosynthesis.
Shozo Fujioka,Jianming Li,Yong Hwa Choi,Hideharu Seto,Suguru Takatsuto,Takahiro Noguchi,Tsuyoshi Watanabe,Hiroki Kuriyama,Takao Yokota,Joanne Chory,Akira Sakurai +10 more
TL;DR: It is shown that DET2 actually acts at the second step in brassinolide biosynthesis in the 5 alpha-reduction of (24R)-24-methylcholest-4-en-3-one, which is further modified to form campestanol, strengthening the argument that brassinosteroids play an essential role in Arabidopsis development.
