| Sumario: | The aim of this work was to characterize the secondary metabolite (SMs) profile of <i>Stemphylium lycopersici</i>, a necrotrophic fungus that causes the disease known as grey leaf spot. We detected twenty-four SMs in cultures of <i>S. lycopercisi</i> within the extracts of 19 isolates. Each of them presented a characteristic unique profile. While highly virulent isolates synthesized a high number of metabolites (15), the low virulent ones synthesized a low number of SMs (2). However, a PCA analysis could not establish the relationship between SMs and virulence. Infectopyrone was the most frequent metabolite produced by the isolates (89%). |
