Flavonoid biosynthesis in Cicer arietinum
Biochimica et Biophysica Acta (BBA) - General Subjects, 1965Abstract 2′,4,4′-Trihydroxy[14C]chalcone or its 4′-glucoside is transformed by chana seedlings in vivo or in cell-free extracts into 4′,7-dihydroxyflavanone, 4′,7-dihydroxyflavanol and 7-hydroxy-4′-methoxyisoflavone. 4′,7-Dihydroxy[14C]flavanolol is not transformed into 7-hydroxy-4′-methoxyisoflavone when administered in vivo or with cell-free ...

Flavonoids: a review on biosynthesis and transportation mechanism in plants
Functional & Integrative Genomics, 2023In recent years, significant progress has been made in understanding the biosynthetic pathway and regulation of flavonoids through forward genetic approaches. However, there remains a notable gap in knowledge regarding the functional characterization and underlying processes of the transport framework responsible for flavonoid transport.

The plant aromatic pathway consists of three segments: the shikimate pathway segment that produces the aromatic amino acids phenylalanine, tyrosine, and tryptophan; the phenylpropanoid segment that produces the cinnamic acid derivatives that are precursors of flavonoids and the plant structural component lignin; and the flavonoid segment that produces ...

Effect of latitude on flavonoid biosynthesis in plants
Plant, Cell & Environment, 2010ABSTRACTThe growth conditions in different latitudes vary markedly with season, day length, light quality and temperature. Many plant species have adapted well to the distinct environments through different strategies, one of which is the production of additional secondary metabolites. Flavonoids are a widely spread group of plant secondary metabolites

Modification of flavonoid biosynthesis in crop plants
Phytochemistry, 2004Flavonoids comprise the most common group of polyphenolic plant secondary metabolites. In plants, flavonoids play an important role in biological processes. Beside their function as pigments in flowers and fruits, to attract pollinators and seed dispersers, flavonoids are involved in UV-scavenging, fertility and disease resistance.

Flavonoid Biosynthesis in Flowers of Verbena hybrida
Journal of Plant Physiology, 1984Extracts from flowers of different strains of Verbena hybrida were found to contain flavones, flavonols, and anthocyanins. Furthermore, the presence of flavanones and dihydroflavonols was demonstrated. With regard to the B-ring substitution pattern, flavonoids with hydroxy groups at the 4'-, the 3',4'-, and the 3',4',5'-positions were found to occur ...

Photocontrol of flavonoid biosynthesis
1994The flavonoids are derived from the flavan or isoflavan skeleton (Fig. 1) and comprise a large group of secondary metabolites from higher plants (Harborne et al. 1975). In the literature the term flavonoid is often used to mean all flavonoids except anthocyanins and for the sake of convenience we have followed this usage.

The role of phenylalanine in flavonoid biosynthesis
Phytochemistry, 1970Abstract The incorporation of 14 C-labelled l -phenylalanine and sucrose into caffeic acid in sunflower discs has been determined under a number of conditions which affect the net rate of synthesis of the latter compound. The results indicate that l -phenylalanine may not be an obligate precursor in the biosynthesis of phenylpropanoid compounds ...

Are flavanones intermediates in flavonoid biosynthesis?
Chemical Communications (London), 1968CHALCONES and flavanones have been shown to be the products from (a) are higher than those from precursors for many classes of flavonoid com- (b). Furthermore, within each experiment, the pounds.l Enzymic and in vitro feeding experi- specific activities of these compounds follow ments, however, show that chalcone and (-)- closely that of the chalcone ...
