Intervention effect AM inoculation significantly improved plant height by 34.3 to 84.7%.
Intervention effect AM inoculation significantly improved root biomass by 10.9 to 27.8%.
Intervention effect Compared with uninoculated plants, AM inoculation elevated leaf P levels by 110.9 to 252.2%.
Intervention effect Compared with uninoculated plants, AM inoculation elevated root P levels by 33.0 to 179.5%.
Intervention effect AM inoculation raised P levels in line with an increase in soil acid, neutral and alkaline phosphatase concentrations.
Observation Roots were the primary site of resveratrol biosynthesis.
Intervention effect Inoculation with F. mosseae increased bioactive compound concentrations in both leaves and roots to varying degrees.
Intervention effect The increase in bioactive compound concentrations was greater when hyphae could pass a 37 um mesh into the P-supplemented hyphal chamber than with a 0.45 um mesh restricting hyphal access.
Intervention effect Extra P supplied to the hyphal chamber further increased root aloe-emodin concentration by 23.1% in AM plants.
Intervention effect Extra P supplied to the hyphal chamber further increased root chrysophanol concentration by 28.5% in AM plants.
Intervention effect Extra P supplied to the hyphal chamber further increased root physcion concentration by 14.8% in AM plants.
Intervention effect Extra P supplied to the hyphal chamber further increased root polydatin concentration by 14.7% in AM plants.
Intervention effect Extra P supplied to the hyphal chamber further increased root resveratrol concentration by 14.4% in AM plants.
Intervention effect Extra P supplied to the hyphal chamber further increased leaf chrysophanol concentration by 138.0% in AM plants.
Intervention effect Extra P supplied to the hyphal chamber further increased leaf physcion concentration by 224.5% in AM plants.
Intervention effect Extra P supplied to the hyphal chamber further increased leaf polydatin concentration by 113.7% in AM plants.
Intervention effect Extra P supplied to the hyphal chamber was accompanied by up-regulated expression of PcCHS1, PcCHS2, PcCRS1 and PcRS genes.
Mechanism The authors conclude that mycorrhizal extraradical hyphal nutrient absorption, especially of P, is a critical mechanism modulating plant growth and bioactive compound production in P. cuspidatum.
