Background
- Traditional cultivation of medicinal plants like Cyclocarya paliurus faces challenges balancing plant growth with secondary metabolism, impacting yield and quality.
- Dark septate endophytes (DSE) are known to enhance plant stress resistance and hormone synthesis, offering a potential solution to this trade-off.
Purpose Of The Study
- To investigate the effects of DSE inoculation on Cyclocarya paliurus growth, stress resistance, and secondary metabolism.
- To elucidate the molecular mechanisms underlying DSE-mediated improvements in medicinal plant cultivation.
Main Methods
- Sterile Cyclocarya paliurus seedlings were inoculated with DSE, with additional treatments including jasmonic acid spraying and inhibition.
- Plant growth parameters (height, biomass), stress indicators (antioxidant barrier, reactive oxygen species homeostasis), and root fungal diversity (ITS sequencing) were assessed.
- Integrated multi-omics analysis was employed to identify key metabolic pathways and molecular players involved.
Main Results
- DSE inoculation significantly increased seedling height (59.46%) and biomass (15.94%), while enhancing plant stress resistance.
- DSE treatment boosted total flavonoid content by 15.30%, notably increasing vitexin levels.
- The study confirmed DSE's role in promoting root fungal diversity and activating the jasmonic acid signaling pathway.
Conclusions
- Dark septate endophytes represent a key factor in synergistically enhancing both yield and quality of medicinal plants.
- This research provides novel insights into eco-efficient cultivation strategies using beneficial fungi for agroforestry applications.
