Elicitation of Isatis tinctoria L. hairy root cultures by salicylic acid and methyl jasmonate for the enhanced production of pharmacologically active alkaloids and flavonoids
2019
Overview
Plant cell and organ cultures via the implementation of effective elicitation strategies can offer attractive biotechnological platforms for the enhanced production of phytochemicals of pharmaceutical interest. For the first time, the elicitation of exogenous signal molecules was conducted to enhance the production of pharmacologically active alkaloids and flavonoids in Isatis tinctoria L. hairy root cultures (ITHRCs). ITHRCs III and V correspondingly possessing high alkaloid and flavonoid productivity were adopted for elicitation treatments. The maximum accumulation of alkaloids in ITHRCs III elicited by 142.61 µM salicylic acid for 28.18 h and flavonoids in ITHRCs V elicited by 179.54 µM methyl jasmonate for 41.87 h increased 5.89- and 11.21-folds as compared with controls, respectively. Moreover, expressions of 11 genes involved in alkaloid and flavonoid biosynthetic pathways were significantly up-regulated following elicitation, among which YUCCA, CHI and F3′H genes might play a crucial role in the target phytochemical augmentation. Overall, two effective elicitation protocols were provided here to improve the yields of bioactive alkaloids and flavonoids in ITHRCs, which was useful for the scale-up production of these valuable compounds to meet the demands for natural bioactive ingredients by pharmaceutical industries.
