Project description:Plants were treated with MeJA and mRNA was extracted and sequenced

Project description:To understand signal transduction mechanism by MeJA in rice, we have analyzed transcription profile with 60K Rice Whole Genome Microarray after MeJA treatment. Gene transcripts were extracted from ten individual rice plants treated with 100 uM MeJA for 6 hrs. RNA samples from these plants were used to generate cyanine-3 (Cy3) and Cy5-labeled complementary DNA (cDNA) probes, which were then hybridized to the microarray. Each data set was obtained from three biological repeats independently.

Project description:We used Affymetrix 1.0 ST arrays to compare the transcriptome of 4 weeks‐day‐old plants sprayed with 250uM of MeJA or mock (control). For the experiments we used wild-type (Col-0), phyB-9 and jaz10 single mutants and jaz10phyb double mutant. Samples were harvested after 3hours of induction with MeJA or mock. We performed a first analysis with the transcriptomes of wild‐type (Col-0) to identify those group of genes that are up‐ and down‐regulated by MeJA treatment (2 fold-changes). We founded 719 genes whose expression was statistically significantly different between the two treatments. To gain knowledge into the regulation of phyB over these set of 719 genes, we contrasted their expression levels against phyB transcriptome. By cluster analysis, we identified five major groups of genes, where in two of them the transcript levels increased in presence of MeJA (clusters 1 and 2) and three whose expression decrease after MeJA treatment (Cluster 3, 4 and 5).

RNA samples from these plants were used to generate cyanine-3 (Cy3) and Cy5-labeled complementary DNA (cDNA) probes, which were then hybridized to the microarray. Each data set was obtained from three biological repeats independently. Preparation of fluorescence labeled probes and microarray hybridization was performed as procedures provided by Genisphere 3DNA Array Detection Array 50 kit (v. 2, Genisphere, Hatfield, PA). The microarray was scanned with Genepix 4000B (Axon Instruments, Union City, CA) and the quality of the chip data was analyzed with statistical R language and sma package in Bioconductor project (http://www.bioconductor.org/) implemented on Linux platform. Noncorrelation of signal and background intensities were confirmed by plotting base 2 log background intensity in x axis and base 2 log intensity subtracted with background intensity in y axis. Prior to normalization, normal distribution of Cy3 and Cy5 intensities were tested by qqplot function in R statistical language. The spatial effects on the chip during the hybridization process were checked with spatial func in sma package. The variance difference between Cy3 and Cy5 intensities within microarray was tested by the Student's t test under the assumptions firstly uniform and then nonuniform variances. The ANOVA difference of signal intensities between microarrays was performed by one-way ANOVA. Block-by-block Lowess normalization (Yang et al., 2002) and multivariate statistics such as clustering, principal component analysis, multidimensional scaling, etc. were analyzed with Acuity 3.1 (Axon Instruments). Spots with flag of 0 and a diameter greater than 51 pixel size were used for the analysis. Cy3 significant spots were determined when its log ratio is less than –0.67 [2**(–0.67) = 1.6-fold decrease] and its background subtracted intensity is higher than 500. On the contrary, Cy5 significant spots was determined when its log ratio is greater than 0.67 [2**0.67 = 1.6-fold increase] and its intensity is higher than 500. A preliminary microarray experiment using nontreated wild-type RNA labeled Cy3 and Cy5, respectively, gave less than 0.5% false positive signals in the analysis. To assess the reproducibility of the microarray analysis, we repeated the experiment three times with independently prepared total RNA

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 3’-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.

Project description:To identify genes involved in the OsDIS1-mediated drought-responsive pathway, we performed microarray analysis of the OsDIS1 overexpression and wild-type plants under both normal and drought stress conditions using the Agilent rice Genechip. Seven-day-old plants of the OsDIS1 overexpression line 9-4-2 as well as the wild-type plants were used in the drought treatment. OsLEA3 was used as a positive control for the drought treatment. Genes with more than two-fold changes in the overexpression plants compared with the wild-type plants were selected. The expression pattern of some differentially expressed genes was further confirmed by real-time PCR.

Project description:Using nylon filter arrays, we analyzed the expression profile of 1536 expressed sequence tags (ESTs) of sugarcane (Saccharum sp.) exposed to the phytormone methyl jasmonate (MeJA) for 0-12 h. 26 ESTs were differentially expressed, including novel genes and also genes that had not previously been reported as being MeJA-inducible. Data are for two independent experiments. Keywords = sugarcane Keywords = methyl jasmonate Keywords = nylon arrays Keywords: time-course

Project description:Dendrobium officinale is a traditional medicinal herb with a mount of bioactive components. Alkaloid is one of the major active ingredients of Dendrobium plants, and its immune regulatory effects have been well-studied. A total of 4857 DEGs, including 2943 up- and 1932 down-regulated genes, were identified between the control and MeJA-treated groups. Several shikimate and methylerythritol 4-phosphate pathway genes and a number of MeJA-induced P450 family genes, aminotransferase genes and methyltransferase genes were identified, providing several important candidates to further elucidate the alkaloid biosynthetic pathway of D. officinale. Furthermore, a large number of MeJA-induced transcript factor encoding genes were identified, suggesting a complex genetic network affecting the alkaloid metabolism in D. officinale.

The expression pattern of some differentially expressed genes was further confirmed by real-time PCR. The OsDIS1 overexpression 9-4-2 plants and the wild-type plants were cultured on 1/2 MS medium plus 3% sucrose for seven days. About half of the plants were sampled as the untreated control for RNA isolation, and the rest were transferred with 1/2 MS medium onto filter papers to induce drought stress. When the leaves of the OsDIS1 overexpression plants began to show drought stress phenotypes, we collected leaves for RNA isolation. OsLEA3 was used as a positive control for the drought treatment.
