Age-dependent Distribution of Fungal Endophytes in Panax ginseng Roots Cultivated in Korea.

ABSTRACT: Fungal endophytes were isolated from 1-, 2-, 3-, and 4-year-old ginseng roots (Panax ginseng Meyer) cultivated in Korea. The isolated fungal endophytes were identified based on sequence analysis of the internal transcribed spacer and morphological characterization by microscopic observations. A total of 81 fungal endophytes were isolated from 24 ginseng roots. Fungal endophytes were classified into 9 different fungal species and 2 unknown species. Ginseng roots that were 1-, 2-, 3-, and 4-years old were colonized by 2, 6, 8, and 5 species of fungal endophytes, respectively. While Phoma radicina was the most frequent fungal endophyte in 2-, 3-, and 4-year-old ginseng roots, Fusarium solani was the dominant endophyte in 1-year-old ginseng roots. The colonization frequencies (CF) varied with
