a Proposed stilbene biosynthetic pathway in grapevines and b effects of various elicitors on stilbene synthase genes (VvSTS6, VvSTS7, VvSTS36, and VvSTS42) expression in grapevine cell cultures. The cells were pre-cultured for 7 days and harvested at different time points after elicitation for qRT-PCR analysis. The elicitors used are as follows: MeJA, methyl jasmonate; SA, salicylic acid; ABA, abscisic acid; ET, ethephon. VvActin7 (XM_002282480.4) was used as a quantitative control. The sequential actions of PAL, C4H, 4CL, STS, and UGT or PRX result in the conversion of phenylalanine to stilbenes. PAL, phenylalanine ammonia-lyase; C4H, cinnamate-4-hydroxylase; 4CL, 4-coumarate-CoA-ligase; STS, stilbene synthase; UGT, UDP-glucosyltransferase; ROMT, resveratrol O-methyltransferase; PRX, peroxidase
