The Impact of Infection on Key Metabolic Properties in 'Red Globe' Berries via Multiomics Approaches.

Grape anthracnose caused by (Shear) is one of the most serious fungal diseases that lead to the quality reduction and yield losses of grape ( 'Red Globe') berries. In the present study, metabolome and transcriptome analyses were conducted using grape berries in the field after infection with at 7, 10, and 13 days to identify the metabolic properties of berries. In total, 132 metabolites with significant differences and 6,877 differentially expressed genes were detected and shared by three comparisons. The analyses demonstrated that phenylpropanoid, flavonoid, stilbenoid, and nucleotide metabolisms were enriched in -infected grape berries but not amino acid metabolism. Phenolamide, terpene, and polyphenole contents also accumulated during infection. The results provided evidence of the enhancement of secondary metabolites such as resveratrol, α-viniferin, ε-viniferin, and lignins involved in plant defense. The results showed the plant defense-associated metabolic reprogramming caused by infection in grape berry and provided a global metabolic mechanism under stimulation.[Formula: see text] Copyright © 2021 The Author(s).
