We characterized two endophyte fungi from the leaves of Astragalus membranaceus in Korea. The isolated strains were identified on the basis of the morphological characters and sequences analysis of the internal transcribed spacer and large subunit regions of the rDNA and β-tubulin gene. To the best of our knowledge, this is the first report of Diaporthe oncostoma and Diaporthe infecunda in Kore...
Coronamycin is a complex of novel peptide antibiotics with activity against pythiaceous fungi and the human fungal pathogen Cryptococcus neoformans. It is also active against the malarial parasite, Plasmodium falciparum, with an IC(50) of 9.0 ng ml(-1). Coronamycin is produced by a verticillate Streptomyces sp. isolated as an endophyte from an epiphytic vine, Monstera sp., found in the Manu reg...
Pathogens are hypothesized to play an important role in the maintenance of tropical forest plant species richness. Notably, species richness may be promoted by incomplete filling of niche space due interactions of host populations with their pathogens. A potentially important group of pathogens are endophytic fungi, which asymptomatically colonize plants and are diverse and abundant in tropical...
Plant tissues host a variety of fungi. One important group is the dark septate endophytes (DSEs) that colonize plant roots and form characteristic intracellular structures - melanized hyphae and microsclerotia. The DSE associations are common and frequently observed in various biomes and plant taxa. Reviews suggest that the proportion of plant species colonized by DSE equal that colonized by AM...
lengthened gestation terms (Waller and Fribourg, 2002; Hemken et al., 1979). The U.S. economic loss in beef Cattle (Bos taurus) consuming tall fescue pastures infected with the associated with this endophyte was estimated at over endophyte Neotyphodium coenophialum often suffer physiological disorders that reduce animal performance. One solution is to replace $600 million annually (Hoveland, 19...
BACKGROUND A key argument in favor of conserving biodiversity is that as yet undiscovered biodiversity will yield products of great use to humans. However, the link between undiscovered biodiversity and useful products is largely conjectural. Here we provide direct evidence from bioassays of endophytes isolated from tropical plants and bioinformatic analyses that novel biology will indeed yield...
Article history: Received on: 18/08/2012 Revised on: 09/09/2012 Accepted on: 05/10/2012 Available online: 29/10/2012 Endophytic fungi inhabit the interior of plants without causing apparent harm to them and constitute an alternative for the control of human pathogens, since they can synthesize bioactive compounds. The plant Piper hispidum Sw. has several medicinal properties and harbors a diver...
Surface cracks create sites for pathogen invasion. Yew trees (Taxus) hyperbranch from long-lived buds that lie underneath the bark [1], resulting in persistent bark cracking and deep air pockets, potentially allowing pathogens to enter the nutrient-rich vascular system (vertical phloem and inter-connected radial medullary rays [MR]). Yew is famous as the source of the anti-cancer diterpenoid dr...
All plants have relationships and associations with animals, invertebrates, other plants, and microbes. This relationship or symbiosis can be beneficial, antagonistic or neither. Turf diseases are a good example of an antagonistic association and conversely, mycorrhizal fungi are a classic example of a beneficial relationship. In this article I want to introduce, or at least review a symbiosis ...
