The biotrophic fungus Erysiphe necator causes powdery mildew (PM) in grapevine. Phytohormones are major modulators of defensive responses in plants but the analysis of the hormonome associated with grapevine tolerance and susceptibility against this pathogen has not been elucidated. In this study, changes in hormonal profiling were compared between...

The aroma of grapes is cultivar dependent and is influenced by terroir, vineyard practices, and abiotic and biotic stresses. Trincadeira is a non-aromatic variety associated with low phenolic content and high sugar and organic acid levels. This cultivar, widely used in Portuguese wines, presents high susceptibility to Botrytis cinerea. This work ai...

Hormones play an important role in response to fungal pathogens. Nevertheless, analyses of hormonal profiling during defense are scarce. In this work, changes in hormonal metabolism in grapevine were compared between a susceptible (Vitis vinifera cv. Aragonês) and a tolerant (Vitis rupestris × riparia) species under infection with powdery mildew. T...
