During 2002-03 forty-four different barley growing regions in East Azarbaijanprovince of Iran were sampled for epiphytic fungi. Isolation of fungi was achieved using standard methods. As the result 374 hyphomycetous isolates were obtained that were placed in 22 genera and 49 species based on colony morphology and microscopic features (Table 1). Among these, Acremonium egyptiacum, A. sclerotigen...

Endophytic fungi live within the tissues of their host plants but, even for fungi, there's no such thing as a free lunch. Some of them pay the rent by producing compounds that protect the host against invading pathogenic microbes. These scanning electron micrographs show three species of endophytic fungus that have mutually beneficial relationships with plants of the family Taxaceae (yews and t...

Susceptibility of sorghum to the fungal pathogen Periconia circinata and sensitivity to its host-specific toxin are determined by the semidominant allele at the pc locus. Pretreatment of susceptible seedlings with cycloheximide or cordycepin for 4 hr before treatment with the toxin protected the seedlings against toxin-induced loss of electrolytes and prevented development of disease symptoms. ...

The study of the fungal community composition in house dust is useful to assess accumulative exposure fungi indoor environments. objective this research was characterize diversity and its association with environmental conditions bedrooms. For this, collected from 41 bedrooms children between ages 8 9 a family history asthma, residents Havana, Cuba. content each sample determined by two methods...

A sensitive and efficient colorimetric method was optimized for detection of esterase enzymes produced by endophytic fungi for development of High-Throughput Screening (HTS). The fungi were isolated and obtained previously from plant species of Cerrado and Atlantic Forest located in areas of environmental preservation in the State of Sao Paulo / Brazil, as part of the project "Chemical and biol...

spores as causal agents in allergies and respiratory diseases. Method: Three periods of sampling have been carried out. The first sampling in 2005 with Rotorod equipment; the quantitative parameters were diversity, volume, and frequency of spores, as well as its relation with meteorological factors, like average temperature, relative humidity, and precipitation; a second study was performed in ...

With the aim of increasing the knowledge about endophytic fungi, a group of microorganisms with high biotechnological potential and a valuable source of useful metabolites, a survey in leaves of mangrove plants (Avicennia schaueriana, Laguncularia racemosa, and Rhizophora mangle) was performed at the Itamaracá Island, PE, Brazil. Leaves were collected, during two seasons, dry and rainy, superfi...

The Cabo Rojo Solar Salterns located on the southwest coast of Puerto Rico are composed of two main ecosystems (i.e., salt ponds and microbial mats). Even though these locations are characterized by high solar radiation (mean light intensity of 39 mol photons m-2d-1) they harbour a diverse microscopic life. We used morphological and molecular techniques to identify a series of halotolerant fung...
