Genetics of Fertility and Mating Type in Magnaporthe Grisea
2004Blast disease of rice (Oryza sativa L.) caused by Magnaporthe grisea (anamorph = Pyricularia grisea) is one of the principal disease of rice. M. grisea includes a large number of monocots among its host range, however individual isolates are specific to only one or few hosts species.

Disruption of a Magnaporthe grisea cutinase gene.
Molecular & general genetics : MGG, 1992Using a one-step strategy to disrupt CUT1, a gene for cutinase, cut1- mutants were generated in two strains of Magnaporthe grisea. One strain, pathogenic on weeping lovegrass and barley and containing the arg3-12 mutation, was transformed with a disruption vector in which the Aspergillus nidulans ArgB+ gene was inserted into CUT1.

The Rice Blast Fungus, Magnaporthe grisea
1997Magnaporthe grisea (Hebert) Barr (Barr 1977; Yaegashi and Udagawa 1978) is a filamentous, heterothallic Ascomycotina that collectively causes disease on many species of the grass (Poaceae) family. M. grisea is the teleomorph corresponding to the previously distinct anamorphs Pyricularia oryzae, infecting rice (Oryza sativa), and P.

RNA Silencing in the Blast Fungus Magnaporthe Grisea
2004We have examined RNA silencing in the blast fungus Magnaporthe grisea using the green fluorescence protein (GFP) gene as a model. The fluorescence in the GFP transformants was efficiently silenced by introducing a plasmid expressing double-stranded GFP RNA. Consequently, GFP mRNA accumulation was drastically reduced in the silenced transformants.

Preliminary Crystallographic Studies on Scytalone Dehydratase from Magnaporthe grisea
Journal of Molecular Biology, 1993Magnaporthe grisea are pathogenic, directly penetrating fungi which cause rice blast disease. Isolated, non-pathogenic mutant strains which are defective in the biosynthesis of dihydroxynapthalene-derived melanin fail to infect host plants and have been shown to lack certain key enzymes in melanin biosynthesis.

Cloning and analysis of CUT1, a cutinase gene from Magnaporthe grisea
Molecular and General Genetics MGG, 1992A gene from Magnaporthe grisea was cloned using a cDNA clone of the Colletotrichum gloeosporioides cutinase gene as a heterologous probe; the nucleotide sequence of a 2 kb DNA segment containing the gene has been determined. DNA hybridization analysis shows that the M. grisea genome contains only one copy of this gene.

A novel gene MGA1 is required for appressorium formation in Magnaporthe grisea
Fungal Genetics and Biology, 2007Insertional mutagenesis is an effective way to study the infection mechanism of fungal pathogens. In an attempt to identify the genes involved in appressorium formation from Magnaporthe grisea, we carried out Agrobacterium tumefaciens mediated transformation (ATMT) of the fungus.

A hybrid machine model of rice blast fungus, Magnaporthe grisea
Biosystems, 2003The fungus, Magnaporthe grisea (Rice blast fungus) is a major agricultural problem affecting rice and related food crops. The way that the fungus invades the host plant and propagates itself is a very important scientific problem and recent advances in research into the genetic basis of these processes can be used to build a simple partial model using ...

On the Trail of a Cereal Killer: Exploring the Biology ofMagnaporthe grisea
Annual Review of Microbiology, 2003▪ Abstract  The blast fungus Magnaporthe grisea causes a serious disease on a wide variety of grasses including rice, wheat, and barley. Rice blast is the most serious disease of cultivated rice and therefore poses a threat to the world's most important food security crop.
