From: Rpv3–1 mediated resistance to grapevine downy mildew is associated with specific host transcriptional responses and the accumulation of stilbenes

Accumulation of stilbenes in susceptible and Rpv3–1 cultivars in response to Plasmopara viticola inoculation. a trans-resveratrol, b trans-pterostilbene, and c ε-viniferin were measured in leaf discs after inoculation with P. viticola isolates (avrRpv3+ or avrRpv3¯) or water control (H2O). Samples were collected 0, 6, 24, 48 and 72 hpi. Bars represent the average of two independent measurements of five pooled biological replicates. Error bars show standard deviation. ANOVA was used to determine the effects of cultivar and treatment (the two isolates) on the stilbene amount and then means were compared by Tukey’s HSD test. Statistical analysis is related to significance of all samples at the same time point, different letters (a, b, c) are significantly different (P < 0.05)
