From: Jasmonates elicit different sets of stilbenes in Vitis vinifera cv. Negramaro cell cultures
Stilbene production in V. vinifera cv. Negramaro cell cultures after elicitation with MeJA and CHI. Determination of cell biomass of V. vinifera cv Negramaro cultures elicited with 100 μM MeJA and 50 μg ml−1 CHI at different time points (A). Quantification of trans-resveratrol (t-R, B), trans-piceid (t-P, C), and viniferins (D) produced by Negramaro cell suspension cultures treated with different elicitors. Quantification was carried out by RP-HPLC using chemically synthesised compounds as external standards. Each point is the average of three independent experiments. Within any given quantification, bars with different letters indicate significant differences between different treatments (p < 0.05, ANOVA test).
