Flavonoid biosynthesis in the tea plant Camellia sinensis: properties of enzymes of the prominent epicatechin and catechin pathways.
Leaves of tea (Camellia sinensis L.) contain extraordinary large amounts of (-)-epigallocatechin, (-)-epicatechin, (+)-gallocatechin, and (+)-catechin and derivatives of these compounds that showExpand

Phloridzin: biosynthesis, distribution and physiological relevance in plants.
The phenolic compound phloridzin (phloretin 2'-O-glucoside, phlorizin, phlorrhizin, phlorhizin or phlorizoside) is a prominent member of the chemical class of dihydrochalcones, which areExpand

Biosynthesis of phloridzin in apple (Malus domestica Borkh.)
Abstract In contrast to the ubiquitously present flavonoids, dihydrochalcones seem to be restricted to approx. 30 plant families. In apple (Malus domestica Borkh.), the dihydrochalcone phloridzinExpand

Flavonoid genes of pear (Pyrus communis)
Pear (Pyrus sp.) is a major fruit crop of temperate regions with increasing extent of cultivation. Pear flavonoids contribute to its fruit color, pathogen defense, and are health beneficialExpand

Substrate specificity and contribution of the glycosyltransferase UGT71A15 to phloridzin biosynthesis
The dihydrochalcone phloridzin (phloretin 2′-O-glucoside) is the most abundant phenolic compound in apple trees (Malus × domestica) and was also discussed to have an influence on the pathogen defenceExpand

Dihydroflavonol 4-Reductase Genes Encode Enzymes with Contrasting Substrate Specificity and Show Divergent Gene Expression Profiles in Fragaria Species
During fruit ripening, strawberries show distinct changes in the flavonoid classes that accumulate, switching from the formation of flavan 3-ols and flavonols in unripe fruits to the accumulation ofExpand

Potent and specific bactericidal effect of juglone (5-hydroxy-1,4-naphthoquinone) on the fire blight pathogen Erwinia amylovora.
A screening of plant quinones for inhibiting effects on the bacterial fire blight pathogen Erwinia amylovora was performed. The most active compound, juglone from walnuts, has a potent and specificExpand

Silencing of flavanone-3-hydroxylase in apple (Malus × domestica Borkh.) leads to accumulation of flavanones, but not to reduced fire blight susceptibility.
Transgenic antisense flavanone-3-hydroxylase apple plants were produced to mimic the effect of the agrochemical prohexadione-Ca on apple leaves. This enzyme inhibitor for 2-oxoglutarate dependentExpand

Cloning and heterologous expression of glycosyltransferases from Malus x domestica and Pyrus communis, which convert phloretin to phloretin 2'-O-glucoside (phloridzin)
Abstract Phloridzin (phloretin 2′- O -glucoside) is the most abundant phenolic compound in apple ( Malus x domestica ) and represents up to 14% of dry weight in leaves. In contrast, the closelyExpand

Investigation of the biosynthesis of 3‐deoxyanthocyanins in Sinningia cardinalis
3-Deoxyanthocyanins provide bright orange-red colours to flowers of some members of the Gesneriaceae, including sinningia (Sinningia cardinalis). We examined 3-deoxyanthocyanin biosynthesis inExpand
