Other claims from this paper (10)
- Observation Detached-leaf inoculation of 176 F1 progenies showed a 1:1 resistant-to-susceptible segregation ratio in grapevine leaf tissues.
- Association Resistant leaves showed enhanced antioxidant enzyme activities that alleviated oxidative stress and delayed fungal colonization.
- Observation Grapevine fruit resistance followed a 1:7 resistant-to-susceptible ratio.
- Association Fruit resistance showed no significant correlation with leaf resistance (R = -0.1779), indicating organ-specific regulation.
- Observation Untargeted metabolomic profiling of resistant and susceptible fruits identified 550 differentially accumulated metabolites.
- Observation Susceptible grapevine fruits showed significant enrichment of the linoleic acid metabolism pathway, with accumulation of lipid peroxidation products that exacerbated membrane damage.
- Association Resistant grapevine fruits showed enhanced accumulation of flavonoid metabolites.
- Mechanism The authors interpret flavonoid metabolites in resistant fruits as conferring resistance through direct antifungal activity.
- Intervention effect Endogenous flavonoid extracts from resistant fruit (100 mg/L in vitro; 50 mg/L for spore disruption) showed significant antifungal activity against B. cinerea.
- Mechanism The authors conclude that grapevine resistance to B. cinerea is governed by an interplay between flavonoid-mediated defense and dysregulated linoleic acid metabolism.
