e0“which was translated into a higher activity of the FLS enzyme producing flavonol-type flavonoids”
t0“Grape Berry Tissues”
t1“Overall, the HL microclimate, compared to that of LL, resulted in a higher expression of genes encoding elements associated with both photosynthesis (VvChlSyn and VvRuBisCO), carbohydrate metabolism (VvSPS1), and photoprotection (carotenoid pathways genes) in both tissues.”

- Observation Exocarp VvSuSy1 expression was highest at the green stage.
- Observation Exocarp VvPAL1 expression was highest at the green stage.
- Observation Exocarp VvSTS1 expression was highest at the green stage.
- Observation Exocarp VvDFR, VvLAR2 and VvANR expression was highest at the green stage.
- Observation Seed VvCHS1 and VvCHS3 expression peaked at véraison.
- Observation Seed VvDFR and VvLAR2 expression peaked at véraison.
- Observation Seed RuBisCO expression persisted to maturity.
- Intervention effect High light raised VvChlSyn and VvRuBisCO expression in both berry tissues relative to low light.
- Intervention effect High light raised VvSPS1 expression in both berry tissues relative to low light.
- Intervention effect High light raised carotenoid pathway gene expression in both berry tissues relative to low light.
- Intervention effect High light induced VvFLS1 expression.
- Intervention effect High light reduced expression of VvCHS3, VvSTS1 and VvDFR.
- Intervention effect High light reduced expression of VvLDOX.
- Mechanism The authors suggested flavonols have a specific photoprotective role in high-light grape berries.
- Mechanism The authors suggested a transcriptional connection between berry photosynthesis and primary and secondary metabolism.
