An ethyl acetate extract of a culture filtrate (ECF) from an unidentified fungal isolate O821 was evaluated for antifungal activity against the rice pathogen Magnaporthe oryzae. The O821-ECF significantly inhibited spore germination, appressorium formation, and mycelial growth of M. oryzae, and its antifungal activity was heat-stable. It also significantly suppressed the number and size of blast lesions. In an analysis of the ITS sequence of this isolate, it shared similarities with species of… Expand

Inhibition of Magnaporthe oryzae by Culture Filtrates of Fungi Isolated from Wild Mushrooms
Analysis of fungi isolated from the fruiting bodies of wild mushrooms indicated that these isolates shared similarities with species of the genera Annulohypoxylon, Nigrospora, and Penicillium, which may yield potential control agents for plant diseases such as the rice blast disease. Expand

Origins of Host-Specific Populations of the Blast Pathogen Magnaporthe oryzae in Crop Domestication With Subsequent Expansion of Pandemic Clones on Rice and Weeds of Rice
The rice-infecting lineage is characterized by high copy number of the transposable element MGR586 (Pot3) and by a loss of AVR-Co39, and host-haplotype association is evidenced by low pathogenicity on hosts associated with other haplotypes. Expand

Emerging fungal threats to animal, plant and ecosystem health
It is argued that nascent fungal infections will cause increasing attrition of biodiversity, with wider implications for human and ecosystem health, unless steps are taken to tighten biosecurity worldwide. Expand
Amplification and direct sequencing of fungal ribosomal RNA genes for phylogenetics
The nuclear small-subunit rDNA sequences (16S-like) evolve rela­ tively slowly and are useful for studying distantly related organisms, whereas the mitochondrial rRNA genes evolve more rapidly and can be useful at the ordinal or family level. Expand
