Endophytic fungi of three leguminous plant roots in Egypt


Abstract: Seventy-eight species, in addition to six varieties belonging to twenty-one genera of endophytic fungi were isolated and identified from the roots of three leguminous plants (peanut, alfalfa and broad bean) on PDA and water agar at 28±2˚C. Fusarium (15 species), Penicillium (16 species) and Aspergillus (12 species and 5 varieties) were the dominant genera of which F. solani, F. subglutinans, F. oxysporum, P. duclauxii, P. funiculosum, A. tubingensis and A. flavus were the most prevalent. The endophytes of peanut and alfalfa were rich in fungal counts (229 & 209 and 230 & 188 colonies/20 samples on PDA and water agar respectively) compared with broad bean (138 & 102 colonies). All isolated fungi belong to Ascomycota and Deuteromycetes. Key words: Endophytes, peanut, alfalfa, broad bean, roots.
