Significance of miRNA in enhancement of flavonoid biosynthesis
Plant Biology, 2021AbstractFlavonoid metabolism shows very strong plasticity in plant development and coping with the changing environment. Flavonoid biosynthesis is regulated by many metabolic pathways, including transcriptional regulation, post‐transcriptional control, post‐translational regulationand epigenetic regulation.

Biosynthesis of flavonoids—XXXIV. Occurrence of the “NIH-shift” in flavonoid biosynthesis
Phytochemistry, 1969Abstract The incorporation of p -tritio-cinnamic acid [3- 14 C] into the flavonols kaempferol and quercetin in pea seedlings ( Pisum sativum ) and into the isoflavones formononetin and biochanin A in chana seedlings ( Cicer arietinum ) was investigated. The retention of tritium found was: kaempferol, 85 per cent; quercetin, 49 per cent; formononetin,

In this chapter we will present a brief overview of flavonoid biosynthesis, along with comments on genetic control of the various steps. Our goal is to demonstrate that the very considerable amount of information that has accumulated on the formation and control of flavonoids in a variety of plant species applies equally well to the pathway in ...

Interest in the biosynthesis of flavonoids was first stimulated by studies on genetic aspects of flower colour (cf. Harborne, 1967; Hess, 1968) and by chemical speculations on the mode of formation of the carbon skeleton of this class of compounds (Birch and Donovan, 1953; Robinson, 1955); tracer studies were first applied to the problem around 1957 ...

Biosynthesis of flavonoids—XV ☆Occurrence and biosynthesis of flavonoids in Datisca cannabina
Phytochemistry, 1968The major flavonoids in Datisca cannabina L. were characterized as datiscetin 3-rutinoside and galangin 3-rutinoside. The incorporation of 2,2′,4t,6t-tetrahydroxychalcone-4′-glucoside-[β-14C] (I), cinnamic acid-[β-14C] (II) and o-hydroxycinnamic acid-[β-14C] (III) into both flavonoids was compared. The dilution of radioactivity upon incorporation of (I)

Biosynthesis of citrus flavonoids and their health effects
Critical Reviews in Food Science and Nutrition, 2018Citrus-derived flavonoids play important roles in the regulation of physiological conditions of citrus plants, including color changes of flower and fruit, flavor development, and anti-stress physiology. Moreover, citrus flavonoids possess multiple health-promoting effects in humans, and they are important ingredients for nutraceuticals and functional ...

Biosynthesis of flavonoids and effects of stress
Current Opinion in Plant Biology, 2002The accumulation of red or purple flavonoids is a hallmark of plant stress. Mounting evidence points to diverse physiological functions for these compounds in the stress response. Advances are also being made toward understanding how plants control the types and amounts of flavonoids that are produced in response to different cues.

Biosynthesis of flavonoids—XVI
Phytochemistry, 1968Abstract The incorporation of dihydrokaempferol-[T] (I) and dihydroquercetin-[T] (II) into kaempfero and quercetin in the pea plant was investigated. (I) is a precursor for both flavonols whereas (II) is a specific precursor for quercetin. These results give further support to the postulated pathway: flavanone → dihydroflavonol → flavonol, in which ...
