Disease relevance of Magnaporthe

 

High impact information on Magnaporthe

  • Trehalose synthesis and metabolism are required at different stages of plant infection by Magnaporthe grisea [2].
  • Here we demonstrate the requirement for an ABC transporter during host infection by the fungal plant pathogen Magnaporthe grisea [3].
  • CYP1 cyclophilin also is the cellular target for CsA in Magnaporthe, and CsA was found to inhibit appressorium development and hyphal growth in a CYP1-dependent manner [4].
  • MAP kinase and protein kinase A-dependent mobilization of triacylglycerol and glycogen during appressorium turgor generation by Magnaporthe grisea [5].
  • The rice blast pathogen Magnaporthe grisea can also penetrate synthetic surfaces such as poly(vinyl chloride) [6].
 

Biological context of Magnaporthe

  • We have initiated a mutational analysis of pathogenicity in the rice blast fungus, Magnaporthe grisea, in which hygromycin-resistant transformants, most generated by restriction enzyme-mediated integration (REMI), were screened for the ability to infect plants [7].
  • Expression of OsBIHD1 was also up-regulated rapidly during the first 6 h after inoculation with Magnaporthe grisea in BTH-treated rice seedlings and during the incompatible interaction between M. grisea and a resistant genotype [8].
  • 9-Methyl 4,8-sphingadienine-containing ceramides are usually glycosylated to form fungal cerebrosides, but the recent description of a ceramide dihexoside (CDH) presenting phytosphingosine in Magnaporthe grisea suggests the existence of alternative pathways of ceramide glycosylation in fungal cells [9].
  • Here we report the characterization of a P-type ATPase-encoding gene, MgAPT2, in the economically important rice blast pathogen Magnaporthe grisea, which is required for exocytosis during plant infection [10].
  • Transcriptional activation of the alternative oxidase gene of the fungus Magnaporthe grisea by a respiratory-inhibiting fungicide and hydrogen peroxide [11].
 

Anatomical context of Magnaporthe

 

Associations of Magnaporthe with chemical compounds

  • Mutants of Magnaporthe grisea harboring a defective gene for 1,3, 8-trihydroxynaphthalene reductase retain the capability to produce scytalone, thus suggesting the existence of a second naphthol reductase that can catalyze the reduction of 1,3,6, 8-tetrahydroxynaphthalene to scytalone within the fungal melanin biosynthetic pathway [13].
  • We describe the isolation and characterization of ICL1 from the rice blast fungus Magnaporthe grisea, a gene that encodes isocitrate lyase, one of the principal enzymes of the glyoxylate cycle [14].
  • CA induced these defense responses more rapidly than did fungal cerebroside, a sphingolipid elicitor isolated from the rice pathogenic fungus Magnaporthe grisea [15].
  • Increased tryptophan decarboxylase and monoamine oxidase activities induce Sekiguchi lesion formation in rice infected with Magnaporthe grisea [16].
  • Metabolomic approaches reveal that phosphatidic and phosphatidyl glycerol phospholipids are major discriminatory non-polar metabolites in responses by Brachypodium distachyon to challenge by Magnaporthe grisea [17].
 

Gene context of Magnaporthe

  • The MAPK gene MAF1, related to Saccharomyces cerevisiae MPK1 and Magnaporthe grisea MPS1, was isolated and functionally characterized [18].
  • The gene encoding the small subunit of the arginine-specific carbamoyl phosphate synthetase, ARG2, of Magnaporthe grisea was characterized to examine the basic regulation of biosynthetic genes in this plant pathogen [19].
  • Isolation of the ERG2 gene, encoding sterol delta 8-->delta 7 isomerase, from the rice blast fungus Magnaporthe grisea and its expression in the maize smut pathogen Ustilago maydis [20].
  • Two PAK kinase genes, CHM1 and MST20, have distinct functions in Magnaporthe grisea [21].
  • To study the signaling processes involved in this special host-pathogen interaction, we have cloned a gene, cpmk1, encoding a mitogen-activated protein (MAP) kinase that shows significant homology to Fus3 of Saccharomyces cerevisiae and to pmk1 of Magnaporthe grisea [22].
