Effects of Arbuscular Mycorrhizal Fungi on the Physiology and Saponin Synthesis of Paris polyphylla var. yunnanensis at Different Nitrogen Levels

Arbuscular mycorrhizal fungi (AMF) are important members of the plant microbiome and affect uptake transfer mineral elements by forming a symbiotic relationship with roots. Nitrogen (N), as an element, can directly growth development at different N levels. It has been confirmed that inoculation AMF improve efficiency utilization plants. However, there still fewer reports on dynamic between arbuscular secondary metabolites nitrogen In this experiment, physiological indexes genes related to saponin synthesis were determined applying concentration gradients medicinal P. polyphylla var. yunnanensis infested test material. was found addition increased biomass, chlorophyll content, nutrient content above- below-ground parts some extent, but more significantly. also promoted expression pathway, including 3-hydroxy-3-methylglutaryl coenzyme A synthase (HMGS), squalene epoxidase 1 (SE1), cycloartenol (CAS), which is in according accumulation may increase plants altering P450s UGTs synthesis.
