ENDOPHYTIC FUNGI MEDIATE Camellia oleifera GROWTH AND PROMOTE OF THE ACCUMULATION OF THE SECONDARY METABOLITES
KAI YAN
Abstract
Endophytic fungi are generally found in plants as beneficial bacteria, establishing a symbiotic relationship with them and enhancing their resistance and promoting growth, etc. To examine the effect of endophytic fungi on the growth of Camellia oleifera, four strains of endophytic fungi isolated from C. oleifera rhizomes were co-cultured with Camellia Oleifera seedlings individually in sterile soil for 49 days: Didymella sp. (DS), Fusarium sp. (FS), Penicillium sp. (PS), and Clonostachys rosea (CR). The experimental results showed that the biological activities of the four fungal strains differed, but all exhibited the promotion of quercetin accumulation and reduction of quercetin glycosides after co-culture with C. oleifera seedlings. DS, FS and PS significantly increased the leaf area of C. oleifera, and all of the experimental groups were more than 50% heavier than the Control (CON). Our results demonstrate the potential utility of endophytic fungi in C. oleifera production with the ability to enhance the productivity and accumulation of plant metabolites.
