Study on the Synergistic Regulation Mechanism of Phenylpropane-Flavonoid Metabolism in Elymus nutans Response to Extract Stress of Ligularia sagitta (PRJCA049456)
The root extract was prepared to determine the ethyl acetate phase as the strongest allelopathic donor and screen the sensitive concentration of the tested plants. The phase was then used to explore the allelopathic stress on seed germination and seedling growth of Weeping Spike. Then the purified monomer compounds were separated and the structure was confirmed, and their sensitive concentrations were screened. Finally, transcriptome and metabolome analysis were performed on sensitive seedlings of extracts and monomer compounds, and the association between genes and metabolites and regulatory pathways were jointly explored.
