Gene expression in rice leaves (Pish) in response to inoculation with rice blast fungus

ABSTRACT: Fourth leaves of rice seedlings (4.5 leaf stage) grown in hydroponic culture were inoculated with rice blast fungus and gene expression profiles were analyzed by microarray. Fourth leaves of the two isogenic lines of rice cv Nipponbare (blast-resistance gene: Pish or its mutant, pish) were inoculated with rice blast fungus, Kyu77-07A, carrying avirulence gene, AvrPish. Total RNA was isolated, labeled with cy3, and probed with agilent rice oligoarray (4x44).

Gene expression in invaded cells and the flanking cells of rice in response to the inoculation with rice blast fungus

Project description:Rice blast fungus was inoculated to susceptible and resistant lines of rice leaves and the invaded cells and their adjacent cells were collected by Laser Microdissection method. The extracted RNA was amplified and analyzed by two color microarray. Two-condition experiment, incompatible (resistant) and compatible (susceptible) combination by using two isogenic lines of rice cv Nipponbare. Biological replicates: 3 replicates. Time course: 4 points.

Transcription profiling of rice plants infected by rice blast fungus

Project description: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. Experiment Overall Design: Agilent rice oligo microarray was used to investigate the gene expression profiling in rice plants infected with Guy11, Mgb1 and Mst12. Total RNAs were isolated from fourth leaves at 24 and 48 hpi. Agilent rice DNA chips were used according to the manufactureâs protocol. After hybridization, arrays were scanned using an Agilent Microarray Scanner, and Feature Extraction version 9.1 was used for image analysis and data extraction. Signal intensities derived from inoculated leaved were compared with that of mock-inoculated leaves. In each treatment, the experiment was performed independently three times.

Effect of overexpression of the rice WRKY transcription factor OsWRKY53 or its phospho-mimicking mutant on rice leaves 48 h after either mock treatment or the rice blast fungus Magnaporthe Oryzae infection

Project description:Analysis of transgenic rice plants overexpressing the rice WRKY transcription factor OsWRKY53 or its phospho-mimicking mutant (OsWRKY53SD). Results provide insight into the roles of OsWRKY53 and its phosphorylation in the basal defense signaling against the rice blast fungus. Expression profiling in wild-type, OsWRKY53- or its phospho-mimicking mutant-overexpressing rice leaves infected with or without Magnaporthe Oryzae was analyzed using one-color method with four biological replicates.

Rice genes responsive to Glu

Project description:Treatment of rice roots with glutamate (Glu) induces systemic disease resistance against rice blast in leaves. To analyze the effect of Glu on the transcriptome of rice, rice roots were treated with Glu solution, and then fourth leaves were harvested and analyzed by Agilent rice microarray.
