Abstract The present study has been carried out at Botany Department, Faculty of Science, New Valley University during April 2018. It concerns the study of endophytic fungi associated with twenty wild (16 plants) and cultivated plant species (4 plants), and production of their cell wall-degrading enzymes as well as growth-promoting compounds and using these compounds for enhancement the growth of the wheat plant. Assessed to the current results, are as follows: 1. Two hundred and eighty-four fungal isolates from 64 species related to 30 genera were isolated and identified from the tested plants. 2. Seventeen fungal species namely Aspergillus creber, Aspergillus keveii, Aspergillus eucalypticola,, Alternaria perangusta, Alternaria citri macularis, Alternaria turkisafria, Alternaria gaisen, Alternaria longipes, Arthrenium euphorbiae, Chaetomium senegalense ,Cladosporium exile, Exserohilum gedarefense, Neosartorya aureola, Rhizopus microspores, Setosphaeria khartoumensis, Stachybotrys zhanymuensis, and Verticillium fungicola were recorded for the first time as endophytes from wild plants. Of which eight species namely Aspergillus creber, Aspergillus keveii, Aspergillus eucalypticola, Alternaria citri macularis, Alternaria turkisafria, Exserohilum gedarefense, Neosartorya aureola, and Stachybotrys zhanymuensis were recorded in the present study for the first time in Egypt. 3. Convolvulus arvensis was the richest wild plant with endophytes attaining 9 genera and 14 species and recording the highest CFUs (87 per 25 segments) comparing with the remaining plant species encountering in 8% of total fungi. Calotropis procera came next to Convolvulus arvensis with CFUs of 85 per 25 segments constituted 7.8% of total fungi, 5 genera and 11 species. While, Moringa oleifera was the poorest in endophytes giving rise to 3 genera and 6 species and the lowest CFUs of 18 per 25 segments having 1.65 % of total fungi. 4. Polypogen monspeliensis was the richest plant with endophytes attaining 8 genera and 12 species and recording the highest CFUs 81 per 25 segments, followed by Rumex dentatus with 4 genera and 6 species and CFUs 61 per 25 segments, and Prosopis farcta by 10 genera and 13 species and recording the highest CFUs 51 per 25 segments over the remaining plant species with 7.4% , 5.6% , 4.7% of the total fungi |
