Abstract: In order to better understanding the relationships between endophytic fungi and root-rot disease of Panax notoginseng (Araliaceae) which is a famous medicinal plant used in pharmaceutical industries. Sixty endophytic isolates were isolated from three artificial plantations, which included healthy and root-rot susceptible individuals of different ages. All isolates were separated based on morphological and ITS sequence analyses into six genera: Alternaria, Colletotrichum, Bionectria, Fusarium, Nigrospora, and Pestalotiopsis and 28 unidentifed species. Twelve species were only isolated from susceptible plants which have never been reported as root-rot pathogens. Nine speceis were only present in healthy individuals. The biodiversity of endophytic fungi is markedly reduced in diseased plants. The highest Shannon-Weiner diversity index for endophytes is from stems of healthy individuals, however different tissues did not significantly different by endophytic species in healthy and susceptible individuals.
