Project description:Rice is one of important crop and, the genome has been already completely sequenced. Moreover we collected more than 30K rice FL-cDNA clones as transcriptome resources. However, the cDNA collection did not reveal the transcription activity and specificity of expression. So, we designed 60-mer oligo array based on the array system of Agilent Technologies (GPL477) as custom array. For validation of the array, we tested the reproducibility of labeling and hybridization. After this validation, 22K rice oligo array was supplied from Agilent Technologies (GPL892). 2: reproducibility of hybridization-2: We made a dye-swap experiment to validate dye-effect and data reproducibility between arrays. We hybridized shoot (as control) and stress-treated shoot. This data also indicated the diversity of gene expression profile among stress response. In addition, array data of samples treated for 24 hours have been already published on NCBI-GEO (GSE2415) Keywords: variety among tissues

After this validation, 22K rice oligo array was supplied from Agilent Technologies (GPL892). 1: reproducibility of labeling: mRNA of shoot sample was amplified and labeled more than 10 times with Cy3 and Cy5, and both Cy3- and Cy5-labeled cRNA was hybridized on a slide (self-hybridization), and validate the reproducibility of labeling. In addition, we also amplified and labeled mRNA of other samples with Cy3 and Cy5, and made a self-hybridization. The intensity data of these array was also indicated transcription activity of genes in these samples. Keywords: variety among tissues

Project description:Expression of the sense-antisense transcripts (SATs). Methods: The sequences of 60mer DNA specific to the sense and antisense genes were chosen by K.K. DNAFORM (Japan), and Agilent Technologies manufactured custom oligo DNA microarray chips by using this information. RNA was labeled and hybridized using Fluorescent Direct Label Kits (oligo dT-primed labeling) (Agilent Technologies), according to the manufacturer's protocols. For labeling with random nanomers, we used the CyScribe First-Strand cDNA Labeling Kit (Amersham). The RNA samples used for microarray experiments were from mouse ES cells, SL10 cells (fibroblast cell line), brain, heart, and testis. The total RNA of brain, heart, and testis for array experiments was purchased from Ambion. The total RNA of ES and fibroblast cells was isolated using Trizol reagent (Invitrogen). The same total RNA samples were reciprocally labeled with Cy3 or Cy5, hybridized to the oligo DNA on the chip, and dye-normalized, and processed signals were obtained using Feature Extraction software (Agilent Technologies).

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:The plant volatile linalool plays important roles in the regulation of defense responses in rice. To clarify the response to linalool 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, many defense-related genes including pathogenesis-related (PR) genes were upregulated in the linalool synthase-overexpressing transgenic rice. An Agilent Rice Oligo Microarray (44k, custom-made; Agilent Technologies, Redwood City, CA, USA) was used for the microarray analysis. Total RNA was extracted from leaf blades of four-leaf stage rice plants. Line 13 was used as the linalool synthase-overexpressing transgenic rice plant. For each biological replicate, material from at least three rice plants was pooled to provide a single sample for RNA extraction. We performed 3 biological replicates for each treatment. All microarray procedures and data analyses were performed according to the manufacturerM-bM-^@M-^Ys instructions. RNA integrity was checked using an Agilent 2100 Bioanalyzer (Agilent Technologies, Redwood City, CA, USA). Total RNA (100 ng) was labeled with Cy-3 using an Agilent Low Input Quick Amp Labeling Kit, One-Color (Agilent Technologies). Fluorescently labeled targets were hybridized to Agilent Rice Oligo Microarrays for 17 h at 65M-BM-0C. After hybridization, following wash processes were performed according to the manufacturerM-bM-^@M-^Ys instructions, and hybridized microarrays were scanned using an Agilent Microarray Scanner (G2565CA; Agilent Technologies). Feature extraction software (Agilent Feature Extraction; Agilent Technologies) was used to delineate and measure the signal intensity of each spot in the array, and to normalize intensities. The background was measured around each spot as local background, calculated by the Feature Extraction software. Statistical data extraction processes were performed according to the manufacturerM-bM-^@M-^Ys instructions.

Project description: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. However, many of these defense-related genes were not upregulated in JA-insensitive transgenic rice plant overexpressing JAZ8deltaC. An Agilent Rice Oligo Microarray (44k, custom-made; Agilent Technologies,?Redwood City, CA, USA) was used for the microarray analysis. Total RNA was extracted from leaf blades of four-leaf stage rice plants that had been treated with 100 ?M JA for 1 day. For each biological replicate, material from at least three rice plants was pooled to provide a single sample for RNA extraction. We performed 4 biological replicates for each treatment. All microarray procedures and data analyses were performed according to the manufacturer’s instructions. RNA integrity was checked using an Agilent 2100 Bioanalyzer (Agilent Technologies, Redwood City, CA, USA). Total RNA (100 ng) was labeled with Cy-3 using an Agilent Low Input Quick Amp Labeling Kit, One-Color (Agilent Technologies).
