This work evaluated the impact of exogenous soil inoculation of beneficial fungal strain Piriformospora indica on phytochemical changes and the related genes expression of Chinese cabbage Brassica campestris ssp. chinensis L. by greenhouse pot experiments. High performance liquid chromatography HPLC affirmed that among the different combinations of fungal and organic fertilizer treatments, the phenolic acids and flavonoids were considerably enriched in organic fertilizer and fungi OP followed by organic fertilizer, biochar, fungi OBP treated plants. The antiradical activity was higher in OP 61.29% followed by P 60% and organic fertilizer OF 53.84% inoculated plants which positively correlated with chlorophyll, carotenoids and flavonoids level P<0.05. Furthermore, results showed that the exogenous application of P. indica significantly P<0.05 enhanced plant growth, as well as stimulating the activation of chlorophyll, carotenoids and other antioxidant related pathways. The RT-qPCR analysis indicated that key FLS gene triggering the synthesis of kaemferol was up-regulated by the inoculation of P. indica. In conclusion, the results revealed that organic fertilizer and P. indica OP is the most appropriate combination for improving phytochemical and antiradical properties in Pakchoi.
