the lpsa gene, a late acting gene in the biosynthetic pathway of ergovaline, a suspected causative agent for fescue toxicosis in cattle, has been cloned from neotyphodium lolii, an endophytic fungus of lolium perenne. in this study, a similar gene was detected in several strains of endophytic neotyphodium spp. isolated from grass hosts endogenous to iran using direct and nested-pcr assays. exce...

soil and water salinity are amongst the severe and progressive problems worldwide which affects most cropland areas of iran. using endophytic microorganisms (which are amongst the most important soil microorganisms) to alleviate the detrimental effect of environmental stresses such as salinity is recently globally considered. in order to test the effects of azospirillum strains and fungus pirif...

Plant endophytic microorganisms represent a largely untapped resource for new bioactive natural products. Eight polyketide natural products were isolated from a mangrove endophytic fungus Phomosis sp. A818. The structural elucidation of these compounds revealed that they share a distinct feature in their chemical structures, an oxygen-bridged cyclooctadiene core skeleton. The study on their str...

Endophytic fungi are rich in species diversity and may play an important role in the fitness of their host plants. This study investigated the diversity and antimicrobial potential of endophytic fungi obtained from Saussurea involucrata KAR. et KIR. A total of 49 endophytic fungi were isolated from S. involucrata and identified using morphological and molecular techniques. Extracts of fermentat...

The fungus Acremonium typhinum produces a novel endoprotease during symbiotic endophytic infection of the grass, Poa ampla. This protease is unusual because it is highly active in the presence of sodium dodecyl sulfate. The enzyme is a thiol-containing serine protease and is localized to a crude membrane fraction. Similar protease activity has been detected in endophyte-infected Poa autumnalis ...

Morphological and molecular methods were used to identify the statues of an isolate, EFY-36, a taxolproducing endophytic fungus. Based on the morphology of the fungal colony, the mechanism of spore production and the characteristics of the spores, the isolate is Mucor spp. Furthermore, the analysis of 18S ribosome RNA sequence of the isolate was achieved using PCR technology. The results showed...

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...

Chemical investigation of the mycelium of Edenia gomezpompae, a newly discovered endophytic fungus isolated from the leaves of Callicarpa acuminata (Verbenaceae) collected from the ecological reserve El Eden, Quintana Roo, Mexico, resulted in the isolation of four naphthoquinone spiroketals, including three new compounds and palmarumycin CP2 (4). We elucidated the structures of the metabolites ...
