Project description:The profiling was conducted with the Rice 3'-Tiling 135k Microarray designed from 31,439 genes deposited at IRGSP, RAP2 database (http://rapdb.lab.nig.ac.jp). In this research, an array of 31,439 rice genes was used to elucidate gene expression in leaf and panicles of non-transgenic and HMB4 over-expression line. The analyses show that transgenic rice induces early flowering due to an enhancement of stress response. A total of 20 chips were used for microarray. Total RNAs were extracted from rice leaf and panicle. Experiments were duplicated.

Project description:To identify genes that are regulated by MeJA and drought, global expression profilings were performed on panicles from Ubi1:AtJMT, drought-treated NT, and untreated NT plants. The underlying assumption of this approach was that high levels of MeJA produced either by overexpression of AtJMT in the transgenic panicles or by drought treatment in the NT panicles regulates genes that are involved in spikelet and/or panicle development. Profiling was conducted using the Rice 3M-bM-^@M-^Y-Tiling Microarray (GreenGene Biotech, Yongin, Korea). RNA samples from S1 panicles of Ubi1:AtJMT, drought-treated NT and untreated NT plants were used to generate cyanine-3 (Cy3)-labeled complementary DNA (cDNA) probes, which were then hybridized to the microarray. Each data set was obtained from three biological repeats. Expression profiling was conducted using a Rice 3M-bM-^@M-^Y-Tiling Microarray. Information on the microarray can be found at http://www.ggbio.com (GreenGene Biotech). The Rice 3M-bM-^@M-^Y-Tiling Microarray was designed from 27,448 genes deposited at IRGSP, RAP1 database (http://rapdb.lab.nig.ac.jp). Among these, 20,507 genes were from representative RAP1 sequences with cDNA/EST supports and 6,941 genes were predicted without cDNA/EST supports. Ten 60-nt long probes were designed from each gene starting 60 bp ahead the end of stop codon with 10 bp shifts in position so that 10 probes covered 150 bp in the 3' region of the gene. In total, 270,000 probes were designed (average size, 60-nt) to have Tm values of 75 to 85 M-BM-0C. The microarray was manufactured by NimbleGen Inc. (http://www.nimblegen.com/). Random GC probes (38,000) were used to monitor the hybridization efficiency and fiducial markers at the four corners (225) were included to assist with overlaying the grid on the image. The microarray was used to profile gene expression in Ubi1:AtJMT, drought-treated NT, and untreated NT plants. Cy3-labeled target cDNA fragments were synthesized from S1 panicles using a Cy3-9mer primer. For normalization, data were processed with cubic alpine normalization using quartiles to adjust signal variation between chips and with Rubust Multi-Chip Analysis using a median polish algorithm implemented in NimbleScan (Workman et al., 2002; Irizarry et al., 2003). To assess the reproducibility of the microarray analysis, we repeated the experiment three times with independently prepared total RNAs.

Project description:The profiling was conducted with the Rice 3'-Tiling 135k Microarray designed from 31,439 genes deposited at IRGSP, RAP2 database (http://rapdb.lab.nig.ac.jp). We have identified and characterized a T-DNA insert rice mutant (Osfuct) with loss of α1,3-fucosyltransferase function. Matrix-assisted laser desorption/ionization time-of-flight analyses of the N-glycan revealed the lack of α1,3-fucose in the N-glycan structure of rice Osfuct mutant. The mutant displayed the pleiotropic developmental defects such as diminished growth, shorter plant height, less number of tillers, shorter panicle lengths and internode, impaired anther and pollen development. In addition, the anther was curved, pollen grains shapes were shriveled, pollen viability and pollen number per anther was dramatically decreased in Osfuct mutant. The complementation test of Osfuct mutant clearly exhibited that the phenotype is caused by the loss of α1,3-fucosyltransferase function bescause complementation line is rescued. Transcriptome profiling data revealed that several genes essential in plant developmental processes were significantly altered in Osfuct mutant including protein kinases, transcription factors, genes involved in metabolism, genes related to protein synthesis and hypothetical proteins. Moreover, Osfuct mutant exhibited the enhanced salt insensitivity. Taken together, these findings demonstrated that Osfuct plays a critical role in growth, anther, pollen development and salt stress response.

Project description:OsMADS1 in rice is an important transcription factor in controlling flower development, not only in flower organs development, but also in floral meristem determinacy. Early flower panicle we used is a high expression stage for OsMADS1. We used microarrays to detail the global gene expression underlying functions of OsMADS1 in rice flower development. Rice panicles in length of 2 mm and 5-7 mm were collectecd for RNA extraction and hybridization on Affymetrix microarrays.Rice panicles in length of 2 mm is the stage for the initiation of inner floral organ development and in length of 5-7 mm is the late stages for floral organ development.Though comparing the microarray data of osmads1 and wild-type (control) at these two stages, we can find the functions of OsMADS1 in the early and late flower development stages. Three biological repeats were used. And totally 12 samples were analyzed.

Project description:The Polycomb Repressive Complex 2 (PRC2) represses the transcriptional activity of target genes through trimethylation of Lysine 27 of Histone H3. The functions of the plant PRC2 have been chiefly described in Arabidopsis but specific PRC2 functions in other plant species, especially the cereals, are still largely unknown. Here we utilize ChIP-seq data in the analysis of protein coding and non-coding RNAs in early WT panicles of rice.

Project description:To understand downstream genes affected by overexpression of OsbHLH148, the Rice 3’-Tiling Microarray analysis (GreenGene Biotech, Yongin, Korea) was carried out to profile gene expression of OsCc1:OsbHLH148 transgenic plants in comparison with wild-type plants under normal growth conditions. RNA samples from these plants were used to generate cyanine-3 (Cy3)-labeled complementary DNA (cDNA) probes, which were then hybridized to the microarray. Each data set was obtained from two biological repeats with independent transgenic lines. Expression profiling was conducted using a Rice 3’-Tiling Microarray. Information on the microarray can be found at http://www.ggbio.com (GreenGene Biotech). The Rice 3’-Tiling Microarray was designed from 27,448 genes deposited at IRGSP, RAP1 database (http://rapdb.lab.nig.ac.jp). Among these, 20,507 genes were from representative RAP1 sequences with cDNA/EST supports and 6,941 genes were predicted without cDNA/EST supports. Ten 60-nt long probes were designed from each gene starting 60 bp ahead the end of stop codon with 10 bp shifts in position so that 10 probes covered 150 bp in the 3' region of the gene. In total, 270,000 probes were designed (average size, 60-nt) to have Tm values of 75 to 85 °C. The microarray was manufactured by NimbleGen Inc. (http://www.nimblegen.com/). Random GC probes (38,000) were used to monitor the hybridization efficiency and fiducial markers at the four corners (225) were included to assist with overlaying the grid on the image. The microarray was used to profile gene expression in OsCc1:OsbHLH148 transgenic and wild-type rice plants. Cy3-labeled target cDNA fragments were synthesized from two-week old seedlings using a Cy3-9mer primer. For normalization, data were processed with cubic alpine normalization using quartiles to adjust signal variation between chips and with Rubust Multi-Chip Analysis using a median polish algorithm implemented in NimbleScan (Workman et al., 2002; Irizarry et al., 2003). To assess the reproducibility of the microarray analysis, we repeated the experiment two times with independent transgenic lines, T-2 and T-9, and analyzed each data set statistically using one-way ANOVA.
