Project description:5 leaves old rice plantlets were infected with Magnaporthe grisea spores and zero, two hours and twenty four houres after infection samples were collected control and 2 hour were mixed and hybridized with chip besides control and twenty four hours were mixed and hybridized with another chip. Both chips were performed in duplicate

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
Project description: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. Keywords: normal vs disease comparison,time course,treated vs untreated comparison
Project description:To evaluate the roles of gene regulation in Oryza sativa leaf, dynamic profiles of transcriptome were investigated in Oryza sativa L. spp. indica with different treatments, the aerial tissues of one-month-old plants from four different areas (groups 1–4) were treated with 0, 40 mL of 25% azoxystrobin, 0.01 g of VdAL, or 40 mL of 25% azoxystrobin plus 0.01 g VdAL, respectively.
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

Keywords: time course, blast infection, disease response Comparison between blast- and mock-infected rice. Biological replicates: 3 control (mock) and 3 blast-infected at each time point, independently grown and harvested at 24 and 48 hours after inoculation. Each sample was prepared with whole plant 5 cm above ground and was pooled from 5 plants grown under the same conditions.
