Antagonistic Activity of Isolated Root Endophytic Freshwater Fungus Anguillospora Longissima Against Pathogenic Fungi

Abstract

Freshwater fungus Anguillospora longissima was recovered as root endophytic fungus from the pteridophytic plant Equisetum sp., growing in riparian areas of Nainital, Kumaun Himalaya, and evaluated through well diffusion and dual culture methods. The isolated endophytic fungus was found a potent inhibitor for test pathogenic fungi. Maximum inhibition by the isolated endophytic fungus was showed against pathogenic fungus Tilletia indica (79.76%), while minimum was recorded against Fusarium oxysporum (35.73%), in dual culture method. Further, in well diffusion method, pathogenic fungi Colletotrichum falcatum and Pyricularia oryzae were found maximum (62.96%) and minimum (17.85%) inhibited fungi, respectively, by the isolated fungus. In the present investigation, the used root endophytic fungus A. longissima was found potent to produce some antifungal substances that inhibited the growth of all test pathogenic fungi.
