bilberry [vaccinium myrtillus linn. (ericaceae)] fruit (vmf) has been traditionally used for treatment of bladder stones, biliary disorders, scurvy, coughs, and lung tuberculosis. vmf may have some pharmaceutical properties owing to these uses, but in vivo and in vitro studies are limited for clarification of medicinal activity and its antidiabetic and antioxidant properties are not investigate...

We show that MAX1, a specific repressor of vegetative axillary bud outgrowth in Arabidopsis, acts a positive regulator of the flavonoid pathway, including 11 structural genes and the transcription factor An2. Repression of bud outgrowth requires MAX1-dependent flavonoid gene expression. As the flavonoidless state leads to lateral outgrowth in Arabidopsis, our data suggest that a flavonoid-based...

Flavonoids play an important role in the grain color and flavor of rice. Since their characterization in maize, the flavonoid biosynthetic genes have been extensively studied in grape, Arabidopsis, and Petunia. However, we are still a long way from understanding the molecular features and mechanisms underlying the flavonoid biosynthetic pathway. The present study was undertaken to understand th...

Rhizopus azygosporus Yuan et Jong (ATCC 48108), a starter culture for fermented soybean tempeh, produces β-glucosidases that cleave flavonoid glycosides into aglycones during fermentation. However, recent data suggest that fermentation of a flavonoid glycoside-rich extract with this strain did not result in the production of aglycones. Thus, in this paper, flavonoid metabolism of this strain wa...

Flavonoid Biosynthesis, Chalcone Synthase, Flavonoid 3'-Hydroxylase, Flavone Synthase II, Sinningia cardinalis Flowers of Sinningia (syn. Rechsteineria) cardinalis contain glycosides of the flavones apigenin (4'-O H ) and luteolin (3',4'-O H ) respectively, and of the related 3-deoxyanthocyanidins apigeninidin and luteolinidin. Studies on substrate specificity of the key enzyme o f flavonoid bi...

A double cropping system has been commercially adopted in southern China, where there is abundant sunshine and heat resources. In this viticulture system, the first growing season normally starts as a summer cropping cycle; then, the vine is pruned and forced, resulting in a second crop in winter. Due to climate differences between the summer and winter growing seasons, grape ripening progressi...

Signal transducer and activator of transcription 3 (STAT3) signaling is constantly activated in human melanoma, and promotes melanoma metastasis. The dietary flavonoid apigenin is a bioactive compound that possesses low toxicity and exerts anti-metastatic activity in melanoma. However, the anti-metastasis mechanism of apigenin has not been fully elucidated. In the present study, we showed that ...

Two outstanding questions in evolutionary biology are whether, and how often, the genetic basis of phenotypic evolution is predictable; and whether genetic change constrains evolutionary reversibility. We address these questions by studying the genetic basis of red flower color in Penstemon barbatus. The production of red flowers often involves the inactivation of one or both of two anthocyanin...
