Serotonin-Salt-Stress Model-Induced Cell Growth via Promoting an Antioxidant System and Secondary Metabolites in Capsicum annuum Cell Suspension Culture.

ABSTRACT: Capsicum annuum contains potential therapeutic capsaicinoids, and various stress factors influence plant productivity. Serotonin is an indoleamine involved in signaling several stress response mechanisms in plants. However, the influence of serotonin on cell growth and the accumulation of secondary metabolites, mainly capsaicinoids production, is not yet clearly defined under salt stress. In this study, we optimized chili cell suspension cultures to maximize biomass, capsaicinoids, and phenolic compounds production using response surface methodology with two variables (serotonin and NaCl) of different concentrations in culture media supplemented with 2,4-dichlorophenoxyacetic acid and Kinetin. The results revealed a significant increase in biomass (14.3 g/L FW), capsaicin (0.93 μg/g
