Article Synopsis
- Bud necrosis (BN) significantly reduces the yield of Vitis vinifera L., and double pruning management is used in Brazilian vineyards to mitigate these losses by optimizing plant cycles during winter and summer.
- RNA-seq analysis of healthy versus necrotic grape tissues reveals that genes associated with cell death are more active in necrotic tissues, potentially due to the influence of endophytic microorganisms.
- The study suggests that harsh conditions and low carbohydrate levels in buds may trigger a shift in endophytic fungi like Alternaria alternata from a biotrophic (nutrient-gain) to a necrotrophic (harmful) mode, contributing to the onset of BN.
