e0“In seeds, the expression of several genes associated with both phenylpropanoid (VvCHS1 and VvCHS3) and flavan-3-ol synthesis (VvDFR and VvLAR2) showed a peak at the véraison stage”
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.”

Other claims from this paper (15)
- 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 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 increased FLS enzyme activity producing flavonol-type flavonoids.
- 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.
