Endophytic fungi (EFs) are one of the important and quantifiable components of fungal biodiversity. In the study, 171 endophytic fungi were isolated from the roots of Aconitum carmichaelii, a traditional Chinese medicine, collected from six production sites of Yunnan Province in southwestern China. These EFs were categorized to belong to 28 taxa by molecular identification, and Chaetomium and Fusarium were the dominant genera with a relative frequency of 16.96% and 16.37% respectively. Cladosporium and Pochonia were found to be unique dominant genera from the roots of A. carmichaelii in Huize and Yulong counties, respectively. The Shannon index ranged from 1.68 to 2.05 and the Simpson's diversity index ranged from 0.81 to 0.92 for the EFs of A. carmichaeli, indicating the rich diversity of EFs in A. carmichaelii. Preliminary screening of the growth inhibition of three severe fungal pathogens by the isolated EFs was conducted and 17 genera of EFs were found to inhibit the growth of the tested pathogens. For example, Acrostalagmus luteoalbus, Phoma sp., and Thielavia sp. each displayed good anti-fungal activity against Alternaria alternate, Fusarium oxysporum f. sp. cucumerinum, and Phytophthora drechleri. The investigation of the root-EFs diversity of A. carmichaelii provides additional fungal resources with the potential to biologically control pathogenic fungi. [ABSTRACT FROM AUTHOR] |
