Association between dipsacus saponin VI level and diversity of endophytic fungi in roots of Dipsacus asperoides

In this study, we isolated and identified 46 endophytic fungal strains from the taproots, lateral roots and leaves, and we used morphological and molecular biological methods to assign them into 15 genera:Fusarium sp.,Ceratobasidium sp.,Chaetomium sp.,Penicillium sp.,Aspergillus sp.,Talaromyces sp.,Cladosporium sp.,Bionectria sp.,Mucor sp.,Trichoderma sp.,Myrothecium sp.,Clonostachys sp.,Ijuhya sp.,Leptosphaeria sp. andPhoma sp. Taproots contained abundant endophytic fungi, the numbers of which correlated positively with level of dipsacus saponin VI. Primary fermentation of several endophytic fungal strains from taproots showed thatFusarium, Leptosphaeria, Ceratobasidium sp. andPhoma sp. can produce the triterpenoid saponin. These results may guide efforts to sustainably produce bioactive compounds fromD. asperoides.Graphical abstract
