Rice genes responsive to Glu

ABSTRACT: 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. Rice plants were treated with Glu (10 mM) or mock (water) solution and leaves were analyzed at 9 and 24 h in two biological replicates.

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

Project description: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: Pia or its mutant, pia) were inoculated with rice blast fungus, P91-15B, carrying avirulence gene, AvrPia. Total RNA was isolated, labeled with cy3, and probed with agilent rice oligoarray (4x44).

WRKY type transcription factor OsWRKY28 overexpression effect on rice leaves 48 h after Magnaporthe Oryzae infection

Project description:Analysis of transgenic rice overexpressing OsWRKY28, a WRKY type transcription factor. Results provide insight into the role of OsWRKY28 in the defense signaling against rice blast fungus. Expression profiling in wild-type and OsWRKY28 overexpressing rice leaves infected with or without Magnaporthe Oryzae was analyzed using one-color method with three biological replicates.

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.

RNA-Seq of Arabidopsis Col-0 and sid2 seedlings treated with L-Glu and urea

Project description:Plant resistance inducers (PRIs) are compounds that protect crops from diseases by activating plant immunity. The exogenous treatment with glutamate (Glu), an important amino acid for living organisms, was shown to induce resistance against fungal pathogen in rice and tomato. To understand the molecular mechanism of Glu-induced immunity, we developed a model system using Arabidopsis thaliana. Here, we found that exogenous treatment with Glu to Arabidopsis enhances resistance against Pseudomonas syringae pv. tomato DC3000 and Colletotrichum higginsianum. Consistently, transcriptome analyses of Arabidopsis seedlings treated with Glu showed that Glu significantly induces the expression of wound, defense, and stress related genes. Interestingly, Glu activates the expression of pathogen or damage associated molecular patterns (PAMP or DAMP)–inducible genes at much later time points than PAMP/DAMPs normally do. Moreover, expression of Glu-inducible genes does not require known components of PAMP receptor complex, glutamate receptors, salicylic acid-biosynthesis enzyme, or glutamate decarboxylase. In addition, Glu also enhances PAMP-inducible immune responses, such as production of reactive oxygen species and mitogen-activated protein kinase activation. These results show that Glu activates PAMP/DAMP-triggered immunity signaling pathway in a novel manner.
