“…These ecological conditions have allowed the development of a wide range of endemic and native plant species [21]. Research of endophytic fungi of these plants is barely developed as we mentioned above; this offers an opportunity to find endophytic fungi or their metabolites with biotechnological potential [22] Plants such as E. chiloensis and B. Linearis inhabit this place. E. chiloensis is the most prominent cactus in central Chile and it can live in Mediterranean pluvial-seasonal and xeric-oceanic climates [23], and only one endophytic fungus has been described on this plant [11].…”

Botrytis cinerea is one of the most important phytopathogens in agriculture worldwide, infecting economically important crops. The main control of this fungus is by synthetic fungicides, causing the selection of resistant isolates. Compounds produced by endophytic fungi have been shown to have antifungal activity against this pathogen and can be used as an alternative to synthetic fungicides. The aim of this work was to isolate endophytic fungi from Chilean foothills in the Metropolitan Region. Ten fungi were isolated from Echinopsis chiloensis and Baccharis linearis, however, only two isolates inhibited the mycelial growth of B. cinerea by antibiosis and were identified as Epicoccum sp. and Pleosporales sp. Extracts at 200 mg L−1 from Epicoccum sp. and Pleosporales sp. showed antifungal activity against B. cinerea of 54.6 and 44.6% respectively. Active compounds in the Epicoccum sp. extracts were mainly alkaloids and phenolic compounds; meanwhile, in the Pleosporales sp. extracts, terpenes and/or saponins were responsible for the antifungal activity.
