Metabolite profiling identifies the mycotoxin alternariol in the pathogen Stagonospora nodorum
A recent comparative proteomics study identified the short-chain dehydrogenase (Sch1) as being required for asexual sporulation (Tan et al. Eukaryotic Cell 7:1916-1929, 2008). Metabolite profiling was undertaken on the mutant strains of Stagonospora nodorum lacking the Sch1 gene to help elucidate its role. Gas chromatography-mass spectrometry of the polar metabolites in the Sch1 mutants identified a secondary metabolite at a 200-fold greater concentration than observed in the wild-type strains....[Show more]
