in vitro assessment of the antifungal activities was evaluated in the present study for both aqueous and ethanol extracts prepared from leaves of avicennia marina and rhizophora mucronata . leaves of mangrove species were collected from qeshm and syrik of south-east coast of iran, mangrove forest respectively. antimicrobial tests were carried out through disk diffusion method. minimum fungicida...

Forest fire is an important occurrence in western landscapes where it helps drive ecosystem processes, and prescribed a common forest management strategy. An initial consequence of burned ground with reduced biodiversity. Numerous studies have documented how forests recover after terms plant regeneration animal colonization, but little known the ecological roles fungi play this process. Pyrophi...

Quercus persica and Pistacia mutica are two known and prevalent forest trees of Baneh and Marivan from Kurdistan province (W Iran). Thirty-five fungal isolates were obtained from 50 bark samples of Q. persica collected in Sept. and Mar. 2010–11. The aim of this study was to identify fungi associated with oak trees of Kurdistan province. Based on morphological features and authentic keys (Ellis ...

Fungi associated with leaf spot symptoms of plants in forest areas of Golestan province, Iran, were collected and examined based on morphological characteristics of conidiophores, conidia and conidiogenous loci. Ten taxa were identified. Among the taxa, Passalora cf. bacilligera and Pseudocladosporium hachijoens are new records for the mycobiota of Iran. Cercospora on Eruca sp. was morphologica...

With improvements in molecular techniques, identification of taxa in mycorrhizal ecology has expanded from fruitbodies to mycorrhizal roots to extraradical hyphae (Anderson & Cairney, 2004). These molecular techniques are, in general, equally applicable to saprotrophic fungi, although this important functional group has received relatively little focus in community studies (Allmer et al ., 2006...

Recent studies have detected phylogenetic signals in pathogen-host networks for both soil-borne and leaf-infecting fungi, suggesting that pathogenic fungi may track or coevolve with their preferred hosts. However, a phylogenetically concordant relationship between multiple hosts and multiple fungi in has rarely been investigated. Using next-generation high-throughput DNA sequencing techniques, ...

BACKGROUND Endophytic fungi, which have been reported in numerous plant species, are important components of the forest community and contribute significantly to the diversity of natural ecosystems. OBJECTIVES The current study aimed to evaluate and characterize, at the molecular level, the diversity and antimicrobial activities of endophytic fungi from medicinal plants in Saudi Arabia. MAT...

1. Previous studies in humid forests have shown that the 13 C and 15 N isotopic composition differs between ectomycorrhizal (ECM) and saprotrophic (SAP) fungi, and that this ECM–SAP ‘divide’ may provide a useful tool for evaluating fungal trophic status. 2. We evaluated whether this method could delineate the trophic status of fungi in two semiarid, temperate forests of the south-western USA. T...

Fires are critical pathways of carbon loss from boreal forest soils, whereas microbial communities form equally critical controls over carbon accumulation between fires. We used a chronosequence in Alaska to test Read’s hypothesis that arbuscular mycorrhizal fungi should dominate ecosystems with low accumulation of surface litter, and ectomycorrhizal fungi should proliferate where organic horiz...
