Treatment with the dioxygenase inhibitor prohexadione-Ca leads to major changes in the flavonoid metabolism of apple (Malus domestica) and pear (Pyrus communis) leaves. Accumulation of unusual… Expand
Suppression of Pythium ultimum by Biowaste Composts in Relation to Compost Microbial Biomass, Activity and Content of Phenolic Compounds
Seventeen composts from separately collected organic household waste plus one bark compost and one compost from grape marc were analysed for suppression of Pythium ultimum, phytotoxicity, microbial… Expand
Biosynthesis of phloridzin in apple (Malus domestica Borkh.)
- C. Gosch, H. Halbwirth, Jasmin Kuhn, Silvija Miosic, K. Stich
- Biology
- 1 February 2009
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 phloridzin… Expand

BackgroundMore than 20,000 cultivars of garden dahlia (Dahlia variabilis hort.) are available showing flower colour from white, yellow and orange to every imaginable hue of red and purple tones.… Expand
Screening for inhibitors of 2-oxoglutarate-dependent dioxygenases: Flavanone 3β-hydroxylase and flavonol synthase☆
- H. Halbwirth, T. Fischer, +4 authors K. Stich
- Biology
- 1 August 2006
Abstract 2-Oxoglutarate-dependent dioxygenases (2-ODDs) catalyze numerous steps in biosynthetic pathways of plants. Prohexadione-Ca is a known inhibitor of such reactions, due to its structural… Expand

Flavonoids are important secondary metabolites in strawberry as they fulfill a wide variety of physiological functions. In addition, they are beneficial for human health. Previous studies have shown… Expand
Biochemical formation of anthocyanins in silk tissue of Zea mays
- H. Halbwirth, S. Martens, U. Wienand, G. Forkmann, K. Stich
- Biology
- 1 April 2003
Two types of anthocyanins are formed in tissues of Zea mays (maize), the common 3-hydroxyanthocyanins and the rare 3deoxyanthocyanins. Their formation is generally controlled by independent… Expand
