Project description:This series examines differential gene expression during appressorium formation induced by exogeous cyclic AMP in the rice blast fungus Magnaporthe grisea. RNA was extracted from spores germinated on hydrophilic (non-inductive) side of GelBond as well as from spores elaborating appressia on hydrophilic surfaces in the presence of cAMP after 9 hrs incubation. RNA from two biological replications of each treatment was pooled in equal amounts and labeled with both cy3 and cy5 dyes using the Agilent Technologies Low Input Linear Amplification Kit. Hybridizations were performed on Agilent Technologies whole genome oligo rice blast arrays (product G4137B) using manufacturer prescribed protocols and reagents in an reference design in which each treatment was paired with every other. This series contains a total of 4 hybridizations; each treatment was used in 4 hybridizations (2 with Cy3 and 2 Cy5). Spot fluorescence was normalized using Lowess within and between microarray slides in Bioconductor. Keywords: Cell development Two-condition experiment, cyclic AMP treated vs. non treated spores. 4 biological replicates with dye-swaps

Project description:This series examines differential gene expression during germination and appressorium formation by the rice blast fungus Magnaporthe grisea. Conidia were germinated on either the hydrophobic (inductive) or hydrophilic (non-inductive) side of GelBond. RNA was extracted from conidia and following incubation for 7 and 12 hours. RNA from two biological replications of each treatment was pooled in equal amounts and labeled with both cy3 and cy5 dyes using the Agilent Technologies Low Input Linear Amplification Kit. Hybridizations were performed on Agilent Technologies whole genome oligo rice blast arrays (product G4137A) using manufacturer prescribed protocols and reagents in an interlaced loop design in which each treatment was paired with every other. This series contains a total of 10 hybridizations; each treatment was used in 4 hybridizations (2 with cy3 and 2 cy5). Spot fluorescence was normalized using Lowess within and between microarray slides in Bioconductor and gene expression profiles analyzed in GeneSpring. Keywords: other

Project description:The rice pathogen, Magnaporthe oryzae, undergoes a complex developmental process leading to formation of an appressorium prior to plant infection. In an effort to better understand phosphoregulation during appressorium development, a mass spectrometry-based study was undertaken. Phosphosites were identified from phosphoproteins from mycelia, conidia, germlings, and appressoria of the wild type and a ckpA mutant. The cyclic-AMP dependent protein kinase A (CPKA) is required for initial perception of the leaf surface, development of functional appressoria, and timely mobilization of storage reserves in conidia, including glycogen and lipid bodies.
