Regional influence and cultivar predisposition affect the prevalence of grapevine fungal pathogens in Portuguese vineyards

| Sumario: | Grapevine fungal pathogens are responsible for substantial yield losses and increased costs for producers aiming to maintain healthy vineyards, making viticulture less cost-effective in heavily affected regions. Fungi that target the woody organs of the vine can cause severe structural damage and plant death, in syndromes collectively known as grapevine trunk diseases (GTDs). The widespread presence of fungi makes it challenging to predict and control outbreaks. We hypothesize that pathogen diversity and prevalence would vary significantly among cultivars and regions. This study assessed commercial vineyards in nine economically important wine-producing regions of Portugal, identifying 312 grapevines with symptoms. Fungal isolates were recovered from necrotic wood tissue and DNA was extracted. Fragment amplification and sequencing allowed the construction of phylogenetic trees, for relationship clarification between taxa. |
