(Submitter supplied) Magnaporthe oryzae causes rice blast, the most devastating foliar fungal disease of cultivated rice. During disease development the fungus simultaneously maintains both biotrophic and necrotrophic growth corresponding to a hemi-biotrophic life style. The ability of M. oryzae to also colonize roots and subsequently develop blast symptoms on aerial tissue has been recognized. The fungal root infection strategy and the respective host responses are currently unknown. more...

(Submitter supplied) The hemibiotrophic fungus Magnaporthe oryzae produces specialized biotrophic invasive hyphae (IH) that alter membrane structure and defense responses in invaded rice cells. IH successively invade live neighbor cells, apparently through plasmodesmata. Understanding fungal and rice genes that contribute to biotrophic invasion has been a challenge because so few plant cells have encountered IH at the earliest infection stages. more...

(Submitter supplied) Two-week old rice plants (cultivar Nipponbare) were treated with either Magnaporthe grisea (virulent isolate FR13) spore suspension in gelatine or gelatine alone. Two time points were taken (3 and 4 days post inoculation- dpi). Disease symptoms were not visible at 3 dpi whereas they were at 4 dpi. Two biological repeats were done.

(Submitter supplied) Rice blast disease is a major threat to rice production worldwide, but the mechanisms underlying rice resistance to the causal agent Magnaporthe oryzae remain elusive. In this whole-genome transcriptome study of rice early defense response to M. oryzae, we applied Affymetrix Rice Genome Genechip to compare the compatible and incompatible rice-M. oryzae interactions in 24 hours post-inoculation.

(Submitter supplied) MicroRNAs (miRNAs) are small non-coding RNAs that function as post-transcriptional regulators of gene expression in eukaryotes. In rice, miR7695 targets an alternatively spliced transcript of natural resistance-associated macrophage protein 6 (OsNramp6) encoding an iron transporter whose expression is regulated by infection with the rice blast fungus Magnaporthe oryzae. Rice plants grown under high iron supply showed blast resistance, which supports that iron is a factor in controlling blast resistance by still unknown mechanisms. more...

(Submitter supplied) The rice-blast fungus Magnaporthe oryzae is disseminated using a three-celled spore or conidium. Upon landing on the surface of a rice leaf, the conidium germinates and forms a specialised structure for entry into the host plant - the appressorium. In this study we have followed gene expression thoughout germination of the conidium and formation of the appressorium to identify genes that may be important for appressorium function. more...

(Submitter supplied) To investigate plant-fungus interactions in early stage of infection, we analyzed response of rice against Magnaporthe grisea infection deficient mutants. In M. grisea, Mgb1 and Mst12 are essential for development of infection structures. Deletion of MGB1 results in defect in appresorium formation, and MST12, in penetration peg development. Analysis of gene expression profiles in rice by microarray revealed the mutant-specific and R gene dependent gene expression, strongly suggesting that gene-for-gene interaction commences before the penetration into rice cell. more...

(Submitter supplied) We created a mutant in the MAP kinase-encoding Pmk1 gene of the rice blast fungus Magnaporthe oryzae (pmk1AS) that renders the gene sensitive to inhibition by 1NA-PP1. Fungal gene expression was compared during infection of rice sheath by the M. oryzae pmk1AS mutant in the presence and absence of 1NA-PP1.
