Plant-mycorrhizal fungal interactions are ubiquitous in forest ecosystems. While ectomycorrhizal plants and their fungi generally dominate temperate forests, arbuscular mycorrhizal symbiosis is common in the tropics. In subtropical regions, however, ectomycorrhizal and arbuscular mycorrhizal plants co-occur at comparable abundances in single forests, presumably generating complex community stru...
Fungal endophytes were isolated from asymptomatic and symptomatic plants of Dactylis glomerata sampled in different ecosystems in Spain. Fungi were identified using morphological, as well as molecular methods based on internal transcribed spacer (ITS) and ribosomal DNA sequencing. Molecular data provided a framework for identification and assessing the phylogenetic position of isolates. One hun...
Sixty-one endophytic fungus strains with different colony morphologies were isolated from the leaves, stems and roots of Tephrosia purpurea with colonization rates of 66.95%, 37.50%, and 26.92%, respectively. Based on internal transcribed spacer sequence analysis, 61 isolates were classified into 16 genera belonging to 3 classes under the phylum Ascomycota. Of the 61 isolates, 6 (9.84%) exhibit...
Trichoderma sp. is one of the endophytic fungi, which is produce toxic culturefiltrate against plant pathogen e.g plant parasitic nematode. Experiments were conducted to in vitro bioassays of the antagonistic effects of culturefiltrate produced by endophytic fungi Trichoderma sp. in different medium on mobility and mortality of Meloidogyne-J2. Three different medium of culturfiltrate were inves...
Fescues (Festuca spp) are widely distributed in the temperate regions and are used for turf, forage and soil conservation. Though seed traits are important measures of the effects of endophytic fungi on their host, little information is available in this respect for Festuca. In this study, endophyte-infected (E+) and endophyte-free (E-) clones of the six fescue genotypes were used to investigat...
Twenty three endophytic fungi from leaf, stem and root of 0cimum basilicum (Tulshi) were isolated and purified. One of the fungi (2L-5) isolated from the leaves was fermented in a large scale and extracted with ethyl acetate. The fungal extract was found to be active against two bacteria, Bacillus cereus and Staphylococcus aureus. From the ethyl acetate extract two steroids, ergosterol and cere...
Endophytic fungi produce a plethora of secondary metabolites, which may open new avenues to study their applicability in pharmaceuticals. Therefore, the present focuses on fungal endophytic community Artemisia asiatica. During our work, endophytes were isolated from medicinal plant, A. The culturable identified using molecular techniques and biodiversity, richness tissue specificity examined. A...
13 strains of endophytic fungi were isolated from Astragalus monadelphus. The radical scavenging activity assay of secondary metabolites and mycelium extracts from these strains were investigated. Results showed that secondary metabolites and mycelium extracts from these strains had significant antioxidant activities. Reducing ability of H401 strain mycelium extracts were stronger than the ethy...
Neurospora crassa has a long history as an excellent model for genetic, cellular, and biochemical research. Although this fungus is known as a saprotroph, it normally appears on burned vegetations or trees after forest fires. However, due to a lack of experimental evidence, the nature of its association with living plants remains enigmatic. Here we report that Scots pine (Pinus sylvestris) is a...
