摘要 [Objectives] To investigate the mechanism of endophytic fungi mediating the plant growth and promoting the accumulation of secondary metabolites in Camellia oleifera. [Methods] Four strains of endophytic fungi isolated from the rhizomes of C. oleifera were co-cultured with C. oleifera seedlings individually in sterile soil for 49 d: Didymella sp. (DS), Fusarium sp. (FS), Penicillium sp. (PS), and Clonostachys rosea (CR). [Results] The biological activities of the four fungal strains differed, but all exhibited the ability to promote quercetin accumulation while simultaneously reducing quercetin glycosides after co-culture with C. oleifera seedlings. The DS, FS and PS treatments resulted in a significant increase in the leaf area of C. oleifera, with all of the experimental groups exhibiting a weight increase of over 50% compared to the control (CON) group. [Conclusions] Our findings demonstrate the potential utility of endophytic fungi in the production of C. oleifera, highlighting their capacity to enhance both productivity and the accumulation of plant metabolites.
