(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) WRKY62 is a transcriptional repressor regulated downstream of WRKY45, a central TF of the salicylic acid (SA) signaling pathway for defense response in rice. To characteraze SA signaling induced genes whose expressions were regulated by WRKY62, we analized genome-wide epression profiles in WRKY62-kd and NB rice using benzothiadiazole (BTH), SA singaling activator.

(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) 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) 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) Rice blast disease is a major threat to rice production worldwide, but the mechanisms underlying rice resistance to the causal agent Magnaporthe oryzae remain elusive. In this whole-genome transcriptome study of rice early defense response to M. oryzae, we applied Affymetrix Rice Genome Genechip to compare the compatible and incompatible rice-M. oryzae interactions in 24 hours post-inoculation.

(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) The WRKY gene family has a very ancient origin but has faced extensive duplication only in the plant kingdom so much that Arabidopsis (Arabidopsis thaliana) has 74 copies of WRKY genes encoding transcription factors while 109 can be found in Rice (Oryza sativa L.). Several studies in the last decade has pointed their involvement in an heterogeneous number of biological processes, from development to hormone signalling, dormancy and senescence, but a wide number of WRKY genes are transcriptionally regulated during biotic or abiotic stresses. more...

(Submitter supplied) Many transcription factors (TFs) in animals bind to both DNA and mRNA, regulating transcription and mRNA turnover. However, whether plant TFs function at both the transcriptional and posttranscriptional levels remains unknown. The rice (Oryza sativa) bZIP TF AVRPIZ-T-INTERACTING PROTEIN 5 (APIP5) negatively regulates programmed cell death and blast resistance and is targeted by the effector AvrPiz-t of the blast fungus Magnaporthe oryzae. more...

(Submitter supplied) Accumulating information indicates that plant disease resistance signaling pathway frequently interact with other pathways regulating developmental processes or abiotic stress responses. However, the molecular mechanisms of these types of crosstalk remain poorly understood in most cases. Here we report that OsWRKY13, an activator of rice resistance to both bacterial and fungal pathogens, functions as a convergent point of the crosstalk between pathogen-induced salicylate-dependent defense pathway and at least five other physiological pathways. more...
