(Submitter supplied) 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.

(Submitter supplied) Benzothiadiazole (BTH) is a so-called ‘plant activator’ and protects plants from diseases by activating the salicylic-acid (SA) signaling pathway. We identified BTH-responsive genes in rice leaves 24 h after treatment using rice 44K microarray. Keywords: response to chemical treatment

Analysis of leaves of Oryza sativa plants treated with benzothiadiazole (BTH). BTH is a functional analog of salicylic acid and enhances the resistance of rice to the fungal pathogen Rhizoctonia solani. Results provide insight into the molecular mechanisms underlying BTH-induced disease resistance.

(Submitter supplied) We used GeneChip Rice Genome Array (Affymetrix, Santa Clara, CA, USA) to identify genes that were rapidly induced by glutamate in rice roots. Transcriptomic analysis of rice roots revealed that the expression of at least 122 genes involved in metabolism, transport, signal transduction, defense, and stress responses was rapidly induced by glutamate within 30 minutes.

(Submitter supplied) NPR1 is a central positive regulator of salicylic-acid (SA)-mediated defense signaling in Arabidopsis. Here, we report characterization of OsNPR1, an Oryzae sativa (rice) ortholog of NPR1, focusing on its role in blast disease resistance and identification of OsNPR1-regulated genes followed by their comparison with NPR1-regulated genes in Arabidopsis. Blast resistance tests using OsNPR1–knockdown and –overexpressing rice lines indicated that OsNPR1 plays an essential role in benzothiadiazole-induced blast resistance. more...

(Submitter supplied) The plant hormone jasmonate (JA) plays important roles in the regulation of defense responses in many plants. To clarify the response to JA in rice at gene expression level, we performed a microarray analysis using the Agilent Rice Oligo Microarray (44k, custom-made; Agilent Technologies, Redwood City, CA, USA). As a result, treatment of JA caused high upregulation of many defense-related genes including pathogenesis-related (PR) genes in rice. more...

(Submitter supplied) Contrary to the relative wealth of information regarding pathogen defense responses in aboveground plant parts, little is known about the mechanistic basis and regulation of plant immunity in root tissues. Aiming to further our fundamental understanding of root immune responses, we have investigated the interaction between rice and one of its major root pathogens, the oomycete Pythium graminicola. The specificic objectives of this study were twofold: i) to disentangle the molecular and genetic basis of the rice-Pythium interaction by comparing the transcriptome of rice roots at different times after inoculation with a highly virulent Pythium strains, and ii) to offer fundamental insights into the genetic architecture and regulation of rice disease resistance pathways operative in root tissue and to identify the molecular players controlling the possible nodes of convergence between these resistance conduits

(Submitter supplied) We used GeneChip Rice Genome Array (Affymetrix, Santa Clara, CA, USA) to identify genes that were rapidly induced by glutamine in rice roots. Transcriptomic analysis of rice roots revealed that the expression of at least 35 genes involved in metabolism, transport, signal transduction, and stress responses was rapidly induced by glutamine within 30 minutes.
