Stable-isotope-assisted metabolomics enables the study of (a)biotic stress-related metabolism of tyrosine compared to phenylalanine in wheat Open
To investigate the role of the previously little-studied tyrosine (Tyr), we have used stable isotope-assisted metabolomics to compare its metabolism to the well-studied phenylalanine (Phe) in wheat. Flowering wheat ears were treated either…

Gramiketides, Novel Polyketide Derivatives of Fusarium graminearum, Are Produced during the Infection of Wheat Open
The plant pathogen Fusarium graminearum is a proficient producer of mycotoxins and other in part still unknown secondary metabolites, some of which might act as virulence factors on wheat. The PKS15 gene is expressed only in planta, so far…

Towards a broader view of the metabolome: untargeted profiling of soluble and bound polyphenols in plants Open
Phenylalanine (Phe) is a central precursor for numerous secondary plant metabolites with a multitude of biological functions. Recent studies on the fungal disease Fusarium head blight in wheat showed numerous Phe-derived defence metabolite…
