ABSTRACT
A total of 187 endophytic fungi were isolated from 11 plant species, which were collected from 11 locations in Korea. Their antifungal activities were screened in vivo by antifungal bioassays after they were cultured in potato dextrose broth and rice solid media. Antifungal activity against plant pathogenic fungi such as Magnaporthe grisea (rice blast), Corticium sasaki (rice sheath blight), Botrytis cinerea (tomato gray mold), Phytophthora infestans (tomato late blight), Puccinia recondita (wheat leaf rust), and Blumeria graminis f. sp. hordei (barley powdery mildew) was determined in vivo by observing the inhibition of plant disease development. Twenty (11.7%) endophytic fungi fermentation broths were able to control, by more than 90%, at least one of the six plant diseases tested. Among 187 liquid broths, the F0010 strain isolated from Abies holophylla had the most potent disease control activity; it showed control values of more than 90% against five plant diseases, except for tomato late blight. On the other hand, fourteen (7.5%) solid culture extracts exhibited potent disease control values of more than 90% against one of six plant diseases. The screening results of this study strongly suggested that metabolites of plant endophytic fungi could be good potential sources for screening programs of bioactive natural products.
