We report the high production of stilbenes, including resveratrol and viniferins, in grapevine (Vitis labruscana L.) cell cultures through elicitation with methyl jasmonate (MJ) and stevioside (STE). Methyl-β-cyclodextrin (CD-M) is widely used as a solubilizer for resveratrol production. For the first time, we used STE as a solubilizer for stilbene production in plant cell cultures. MJ was most effective in activating VvSTS expression and stimulating stilbene biosynthesis and induced accumulation of trans-piceid in the cells. High levels of trans-resveratrol and δ-viniferin production were observed in the culture medium when CD-M and STE, respectively, were used as solubilizers, but neither were significantly elevated within the cells. Maximum production of trans-resveratrol (12.2 mg/L) and δ-viniferin (892.2 mg/L) was observed 5 days after elicitation of cells with MJ and STE in shake flask cultures. Notably, predominant production of δ-viniferin and trans-resveratrol was observed in shake and static flask culture medium, respectively. Furthermore, stilbene compounds of resveratrol, e-viniferin, and δ-viniferin were mainly produced in a 3 L bioreactor culture following elicitation of cells with MJ and STE. These results provide new strategies for conditional, high-level production of resveratrol and viniferins in cell cultures by utilizing the solubilizing properties of STE or CD-M.
