The Transcription Factors NFYA1 and GBF3 Jointly Regulate CHS2 to Promote Tangeretin Accumulation and Cold Tolerance in Citrus

Plant Biotechnology Journal, EarlyView.
ABSTRACT Tangeretin has been known as a polymethoxylated flavone conferring both phytoprotection and nutraceutical value, but cryoprotective roles and molecular regulation of tangeretin under abiotic stresses remain largely unexplored. In this study, we demonstrated that cold treatment led to greater accumulation of tangeretin and upregulation of ...

CsYABBY1 and CsMYB114 Enhance Acquired Drought Tolerance by Mediating Flavonoid Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Drought priming is a critical agronomic strategy for enhancing plant drought tolerance, yet the optimal priming intensity and transcriptional regulatory mechanisms underlying subsequent drought responses in the tea plant (Camellia sinensis) remain poorly characterised.

Engineering of the Flavone Rutinoside Biosynthetic Pathway Enables Production of Diosmin, a Venoactive Compound in Solanum lycopersicum and Nicotiana tabacum

Plant Biotechnology Journal, EarlyView.
ABSTRACT Diosmin is often used as a dietary supplement, and it is sometimes used to make phlebotropic drugs for venous diseases. Traditionally, diosmin is obtained by the dehydrogenation of the flavanone glycoside hesperidin through chemical semisynthesis.

Vasodilator Effects of Quercetin 3-O-Malonylglucoside Are Mediated by the Activation of Endothelial Nitric Oxide Synthase and the Opening of Large-Conductance Calcium-Activated K⁺ Channels in the Resistance Vessels of Hypertensive Rats

Molecules
We used molecular docking as a computational tool to predict the binding affinities and interactions of quercetin 3-O-malonylglucoside (Q3MG) with vascular target proteins. First, the proteins 1M9M (human endothelial nitric oxide synthase; eNOS) and 6ND0

Flavones: From Biosynthesis to Health Benefits

Plants, 2016
Flavones correspond to a flavonoid subgroup that is widely distributed in the plants, and which can be synthesized by different pathways, depending on whether they contain C- or O-glycosylation and hydroxylated B-ring.
