Project description:The plant volatilebeta-cyclocitral plays important roles in the regulation of defense responses in rice. To clarify the response to beta-cyclocitral 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 linalool caused high upregulation of many defense-related genes including pathogenesis-related (PR) genes in rice.
Project description: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
Project description:This SuperSeries is composed of the following subset Series: GSE32633: Jasmonic acid-responsive genes in suspension-cultured rice cells GSE32634: Jasmonic acid-responsive genes in rice leaves Refer to individual Series
Project description:Jasmonic acid (JA) is involved in various developmental processes and defense responses against abiotic and biotic stresses. We identified JA-responsive genes in rice leaves 6-48 h after treatment using rice 44k microarray.
Project description:A rice transcription factor OsMYC2 plays important role in the regulation of defense responses in rice. To clarify the OsMYC2-responsive genes, we performed a microarray analysis using the Agilent Rice Oligo Microarray (44k, Agilent Technologies, Redwood City, CA, USA). As a result, many defense-related genes including pathogenesis-related (PR) genes were upregulated in the OsMYC2-overexpressing transgenic rice.
Project description:Benzothiadiazole (BTH) is a so-called âplant activatorâ 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 BTH-treated leaves were compared with mock-treated leaves using single-color method with 4 biological replicates.
Project description:Jasmonic acid (JA) is involved in various developmental processes and defense responses against abiotic and biotic stresses. We identified JA-responsive genes in suspension-cultured rice cells 2-12 h after treatment using rice 44k microarray.
Project description:To characterize plant heat stress-responsive genes and to clarify the heat stress-responsive transcription pathways, the transcriptome analysis of rice was conducted using microarray. Rice (Oryza sativa L. cv. Nipponbare) were grown in plastic pots filled with nutrient soil for 2 weeks with a 12 h light (28°C)/12 h dark (25°C) regimen (ca. 1500 μmol photons mâ2 sâ1) and were treated for 30 min at 42°C.
Project description:Jasmonic acid (JA) is involved in various developmental processes and defense responses against abiotic and biotic stresses. We identified JA-responsive genes in rice leaves 6-48 h after treatment using rice 44k microarray. Expression profiling in rice leaves treated with JA for 6, 12, 24 and 48 h was compared with that in the corresponding mock control using two-color method with two biological replicates.
Project description:Cytokinins (CKs) are a class of plant hormones that regulate many aspects of growth and development, including cell division, apical dominance, leaf senescence, nutrient signaling, and shoot differentiation. In the past decade, substantial progress has been made in understanding CK biosynthesis, metabolism and signal transduction. Much of this knowledge is based on research in Arabidopsis, a dicotyledonous model plant. Although cytokinin plays an important role for growth and development in the Gramineae, our knowledge of cytokinin responsive genes in monocotyledonous species is very limited compared to Arabidopsis. The search for genes whose expression is modified by CK has yielded a number of valuable tools that have been used to understand CK signaling and the complex developmental processes under control of this hormone. We tried to identify rice genes regulated by CK using an Affymetrix rice genome array. Keywords: time_course; hormone_response; organ_specific_response
