Article Synopsis
- The study investigates how arbuscular mycorrhizal fungi (AMF) influence the composition of bioactive saponins in a valuable medicinal herb from China, using advanced mass spectrometry techniques.
- Researchers identified a total of 202 terpenoid metabolites, with 150 being triterpene glycosides, and found significant differences between samples treated with AMF and control samples.
- The treatment with AMF led to an increase in specific notoginsenosides and suggested that the pathways for synthesizing rare notoginsenosides are activated by AMF, potentially enhancing the ecological farming of medicinal herbs.
is a highly valued perennial medicinal herb plant in Yunnan Province, China, and the taproots are the main medicinal parts that are rich in active substances of saponins. The main purpose of this study is to uncover the physiological and molecular mechanism of saponin accumulation triggered by methyl jasmonate (MeJA) under arbuscular mycorrhizal fungi (AMF) by determining physiological indices, high-throughput sequencing and correlation analysis. Physiological results showed that the biomass and saponin contents of , the concentrations of jasmonic acids (JAs) and the key enzyme activities involved in notoginsenoside biosynthesis significantly increased under AMF or MeJA, but the interactive treatment of AMF and MeJA weakened the effect of AMF, suggesting that a high concentration of endogenous JA have inhibitory effect.
