Metabolomics Reveals Resistance-Related Secondary Metabolism in Sweet Cherry Infected by <i>Alternaria alternata</i>.

ABSTRACT: Sweet cherry (Prunus avium L.) is a tree species cultivated worldwide with high economic value. During its growth, it is frequently threatened by pathogenic fungi, leading to reduced yield and deteriorated quality. However, in sweet cherry, the disease-resistant cultivars against brown spot disease (BSD) caused by Alternaria alternata, as well as the associated disease-resistant metabolic pathways and metabolites, remain limited. In this study, we investigated the disease-resistant germplasm and associated metabolic pathways of sweet cherries using field disease resistance screening, physiological analyses, and metabolomics. The results showed that sweet cherry cultivar Q8 exhibited relatively strong resistance to BSD, while cultivar Q9 demonstrated the weakest resistance. Ph
