Antimycotic activity of three fern extracts from Hemionitis arifolia (Burm.f.) Moore., Pteridium aquilinum (Linn.) Kuhn. and Christella parasitica (Linn.) H. Lev. were evaluated against groundnut early leaf spot and rust disease causative agents viz., Puccinia arachidis Speg. and Phaeoisariopsis personata (Berk & M.A. Cuortis) Vanarx., espectively by mycelial dry weight method. Both the fungi w...

this study was carried out to evaluate the in vitro and in vivo antifungal efficacy of essential oil and extracts derived from the flower and leaves of magnolia liliflora, respectively, against plant pathogenic fungi. the oil (750 μg disc-1) and various leaf extracts such as hexane, chloroform, ethyl acetate and methanol (1,500 μg disc-1) revealed promising antifungal effects against botrytis c...

Cladosporium musae, a widespread leaf-spotting hyphomycete on Musa spp., is genetically and morphologically distinct from Cladosporium s. str. (Davidiella anamorphs, Mycosphaerellaceae, Dothideales). DNA sequence data derived from the ITS and LSU gene regions of C. musae isolates show that this species is part of a large group of hyphomycetes in the Chaetothyriales with dematiaceous blastoconid...

While Hymenoscyphus fraxineus causes dieback of the European ash (Fraxinus excelsior), flowering ash (F. ornus) appears resistant to the pathogen. To date, contributions of endophytic fungi to host resistance are unknown. The following hypotheses were tested: (i) endophytic fungi enhance the resistance of F. excelsior to the pathogen; (ii) resistance of F. ornus relies on its community of endop...

Plants response to symbiosis with arbuscular mycorrhizal fungi (AMF) under water stress is important to agriculture. Under abiotic stress conditions native fungi are more effective than exotics in improving plant growth and water status. Mycorrhization efficiency is related to soil fungi development and energy cost-benefit ratio. In this study, we assessed the effect on growth, water status and...

The contribution of fungi and bacteria to the decomposition of alder leaves was examined at two reference and two polluted sites in the Ave River (northwestern Portugal). Leaf mass loss, microbial production from incorporation rates of radiolabeled compounds into biomolecules, fungal biomass from ergosterol concentration, sporulation rates, and diversity of aquatic hyphomycetes associated with ...
