Resumen:
Endophytic fungi areubiquitous and live within host plants without causing any noticeable symptomsof disease. Little is known about the diversity and function of fungalendophytes in plants, particularly in economically important species. The aimof this study was to determine the identity and diversity of endophytic fungiin leaves, stems and roots of soy-bean and corn plants and to determine theirinfection frequencies. Plants were collected in six areas of the provinces ofBuenos Aires and Entre Ríos (Argentina) two areas were selected for samplingcorn and four for soybean. Leaf, stem and root samples were surface-sterilized,cut into cm2 pieces using sterile scalpel and aseptically transferred to platescontaining potato dextrose agar plus antibiotics. The species were identifiedusing both morphological and molec-ular data. Fungal endophyte colonization insoybean and corn plants was influenced by tissue type and varieties whereas incorn plants only by tissue type. greater number of endophytes were isolatedfrom stem tissues than from leaves and root tissues in both species of plants.The most frequently isolated species in all soybean cultivars was Fusariumgraminearum and the least isolated one was Scopulariopsis brevicaulis.Furthermore, the most frequently isolated species in corn plants wasAspergillus terreus whereas the least isolated one was Aspergillus flavus.These results could be relevant in the search for endophytic fungi isolatesthat could be of interest in the control of agricultural pests
