ABSTRACT: 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.
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. Samples were taken from mycelium grown in both complete medium and in glucose minimal medium. Three replicates were taken for each condition.

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.

Samples were taken from five time-points in wild-type germinating conidia and one time-point in the pmk1 mutant. Two replicates were taken at each time-point.

Project description:To investigate the role of iron excess in rice immune responses to Magnaporthe oryzae infection. Gene expression profiling analysis were performed using data obtained from RNA-seq of rice plants grown in differential iron supply and challenged with Magnaporthe oryzae spores.
Project description:Rice blast, caused by the fungal pathogen Magnaporthe grisea, is a devastating disease causing tremendous yield loss in rice production. The public availability of the complete genome sequence of M. grisea provides ample opportunities to understand the molecular mechanism of its pathogenesis on rice plants at the transcriptome level. To identify all the expressed genes encoded in the fungal genome, we have analyzed the mycelium and appressorium transcriptomes using MPSS, RL-SAGE and oligoarray methods. Keywords: RL-SAGE, oligoarray

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
