Ingia / Ingia

2D DOSY 1H NMR has proved to be a useful technique in the identification of the molecular skeleton of the four major compounds of ethyl acetate extract of aerial parts of Bidens sulphurea (Asteraceae). The combination of this technique with HPLC, mass spectrometry and other NMR techniques enabled

Ingia / Ingia

A chalcone 3-hydroxylase (CH3H) cDNA clone was isolated and characterized from Cosmos sulphureus petals accumulating butein (2',3,4,4'-tetrahydroxychalcone) derivatives as yellow flower pigments. The recombinant protein catalyses the introduction of an additional hydroxyl group in the B-ring of

Transgenic apple plants overexpressing the chalcone 3-hydroxylase gene of Cosmos sulphureus show increased levels of 3-hydroxyphloridzin and reduced susceptibility to apple scab and fire blight.

CONCLUSIONS Overexpression of chalcone-3-hydroxylase provokes increased accumulation of 3-hydroxyphloridzin in Malus . Decreased flavonoid concentrations but unchanged flavonoid class composition were observed. The increased 3-hydroxyphlorizin contents correlate well with reduced susceptibility to

Evaluation of a MdMYB10/GFP43 fusion gene for its suitability to act as reporter gene in promoter studies in Fragaria vesca L. 'Rügen'.

Ingia / Ingia

A Malus domestica MdMYB10 transcription factor gene was previously used as visible marker for successful plant transformation. We combined the MdMYB10 transcription factor gene with a GFP gene to test its viability as a non-destructive, visual, double reporter system for functional promoter studies
