Molecular basis of drought-induced susceptibility to the rice blast fungus Magnaporthe oryzae

Project description:In order to understand the mechanisms of Drought induced susceptibility (DIS) we’ve conducted a dual RNAseq experiment on rice infected tissues by Magnaporthe oryzae. At 4 days post inoculation tissues have been collected on mock inoculated and M. oryzae inoculated plants. Rice were conducted under two type of water regime: DIS Drought during three days before inoculation, NoDIS no drought before inoculation. RNAseq was conducted both on rice and fungal RNA.

Hierarchical transcriptional network controls appressorium-mediated plant infection by the rice blast fungus Magnaporthe oryzae

Project description:We report that the homeobox trasncription factor called HOX7 controls hyphae-associated genes, autophagy and cell cycle related genes necessary for appressorium development in the rice blast fungus Magnaporthe oryzae. We also report that the ste transcription factor MST12 regulates gene functions involved in septin reorientation.

Comparison of transcript abundance in mycelium from the rice blast fungus Magnaporthe oryzae grown in rich medium and in minimal medium using HT-SuperSAGE.

Project description:Mycelium from the rice blast fungus Magnaporthe oryzae was grown in both rich medium and under nutrient limiting conditions. Genes were identified that were more highly expressed in one condition as compared to the other.

Transcriptome analysis of rice (Oryza sativa) infected with blast fungus (Magnaporthe oryzae)

Project description:Rice blast is one of the most serious diseases and is caused by Magnaporthe grisea. SHZ-2, an indica cultivar with broad spectrum resistance to multiple races of the blast pathogen, was crossed to TXZ-13, a blast susceptible but high-quality variety, to produce one BC3 line, BC10 line, which showed strong to moderate blast resistance over eight cropping seasons in the field. In this study, we compared the transcription between blast-resistant and -susceptive lines by custom microarray. Keywords: time course, blast infection, disease response

Temporal gene expression analyisis from rice root (cv. Nipponbare) infected with Magnaporthe oryzae strain Guy11

Project description: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. Global temporal expression analysis suggested a purely biotrophic infection process reflected by the rapid induction of defense response-associated genes at the early stage of root invasion and subsequent repression coinciding with the onset of intracellular fungal growth. The same group of down-regulated defense genes was increasingly induced upon leaf infection by M. oryzae where symptom development occurs shortly post tissue penetration. Our molecular analysis therefore demonstrates the existence of fundamentally different tissue-specific fungal infection strategies and provides the basis for enhancing our understanding of the pathogen life style.

Analysis of transcript abundance during appressorium formation in the rice blast fungus Magnaporthe oryzae using HT-SuperSAGE.

Project description: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. We have also compared gene expression in the wild-type germinating conidium at four hours to a mutant strain deleted for the MAP kinase pmk1. The pmk1 mutant is unable to form appressoria.
