Differential cDNA cloning was used to identify genes expressed during infectious growth of the fungal pathogen Magnaporthe grisea in its host, the rice plant. We characterized one of these genes, MPG1, in detail. Using a novel assay to determine the proportion of fungal biomass present in the plant, we determined that the MPG1 transcript was 60-fold more(More)
Neurospora crassa is a central organism in the history of twentieth-century genetics, biochemistry and molecular biology. Here, we report a high-quality draft sequence of the N. crassa genome. The approximately 40-megabase genome encodes about 10,000 protein-coding genes--more than twice as many as in the fission yeast Schizosaccharomyces pombe and only(More)
Magnaporthe grisea is the most destructive pathogen of rice worldwide and the principal model organism for elucidating the molecular basis of fungal disease of plants. Here, we report the draft sequence of the M. grisea genome. Analysis of the gene set provides an insight into the adaptations required by a fungus to cause disease. The genome encodes a large(More)
We present an analysis of over 1,100 of the approximately 10,000 predicted proteins encoded by the genome sequence of the filamentous fungus Neurospora crassa. Seven major areas of Neurospora genomics and biology are covered. First, the basic features of the genome, including the automated assembly, gene calls, and global gene analyses are summarized. The(More)
Neurospora crassa is a filamentous fungus that grows on semisolid media by forming spreading colonies. Mutations at several loci prevent this spreading growth. cot-1 is a temperature sensitive mutant of N.crassa that exhibits restricted colonial growth. At temperatures above 32 degrees C colonies are compact while at lower temperatures growth is(More)
Mycoparasitism, a lifestyle where one fungus is parasitic on another fungus, has special relevance when the prey is a plant pathogen, providing a strategy for biological control of pests for plant protection. Probably, the most studied biocontrol agents are species of the genus Hypocrea/Trichoderma. Here we report an analysis of the genome sequences of the(More)
The fungus Trichoderma virens is a ubiquitous soil saprophyte that has been applied as a biological control agent to protect plants from fungal pathogens. One mechanism of biocontrol is mycoparasitism, and T. virens produces antifungal compounds to assist in killing its fungal targets. Peptide synthetases produce a wide variety of peptide secondary(More)
Many processes in fungi are regulated by light, but the molecular mechanisms are not well understood. The White Collar-1 (WC-1) protein is required for all known blue-light responses in Neurospora crassa. In response to light, WC-1 levels increase, and the protein is transiently phosphorylated. To test the hypothesis that the increase in WC-1 levels after(More)
The rice blast pathosystem has been the subject of intense interest in part because of the importance of the disease to world agriculture, but also because both Magnaporthe oryzae and its host are amenable to advanced experimental approaches. The goal of this review is to provide an overview of the system and to point out recent significant studies that(More)
MAP kinases homologous to Saccharomyces cerevisiae Fus3p/Kss1p have been identified in plant pathogenic fungi and are required for pathogenicity and sexual reproduction. To better understand the role of MAP kinase signaling in Neurospora crassa, and to identify downstream target genes of the pathway, we isolated, cloned, and disrupted the FUS3 homolog(More)
