Sample GSM207559 Query DataSets for GSM207559
Status Public on Jul 02, 2008
Title Mudanjiang8 OsWRKY13 Overexpressing D11UM1-1 rep2
Sample type RNA
Source name Mudanjiang8 OsWRKY13 Overexpressing tansgenic plant D11UM1-1
Organism Oryza sativa
Characteristics OsWRKY13-overexpressing independent transgenic line T3 D11UM1-1
Growth protocol Leaves of a 20 different plants pool were harvested from the 4-week old wild-type Mudanjiang 8 (Oryza sativa ssp. japonica) and OsWRKY13-overexpressing independent transgenic lines (D11UM1-1 and D11UM7-2) growing in the greenhouse at 26°C with 12 hours daylight. The experiment was repeated three times.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted with TRIZOL reagent (Invitrogen, Gaithersburg, MD) and was further purified with Nucleospin RNA Clean-up Kit (Macherey-Nagel, Germany) according to the manufacture’s instructions. The RNA quality was assessed by formaldehyde agarose gel electrophoresis and concentration was quantitated by spectrophotometric analysis.
Label biotin
Label protocol Biotin labeled cRNA was produced with MessageAmp II-Biotin Kit (Ambion Inc., Texas) with 5 ug of total RNA as starting material for each sample reaction.
Hybridization protocol Fifteen micrograms of the resulting biotin-tagged cRNA was fragmented to strands of 35 to 200 bases in length following prescribed protocols (Affymetrix GeneChip Expression Analysis Technical Manual). Subsequently, 10 g of this fragmented target cRNA was hybridized at 45°C with rotation for 16 h (Affymetrix GeneChip Hybridization Oven 320) to probe sets on an Affymetrix Genechip Rice Genome Array.
Scan protocol The chip was washed and then stained with streptavidin-phycoerythrin on an Affymetrix Fluidics Station 400, followed by scanning on a GeneChip Scanner 3000 (Affymetrix, Inc.).
Description The results were quantified and normalized using MicroArray Suite 5.0 (GCOS1.4) software (Affymetrix, Inc.).
Data processing The genes with probe set signal lower than 100 on the repeated six arrays were considered as non-expression and filtered out (Hu and Ma, 2006), resulting in 24283 expressed genes in rice line D11UM1-1 and 24293 expressed genes in D11UM7-2 for further analysis. The Significance Analysis of Microarrays (SAM) Excel Add-in (Tusher et al., 2001) was used to identify significantly differentially expressed genes between the control and OsWRKY13-overexpressing plants. The number of permutation for SAM analysis was 100. The delta value in the SAM was adjusted so that the estimated false discovery rate (FDR) was < 5% for significant genes. The cutoff value of expression fold change was set as 2.0 that was commonly used for microarray analysis to further increase the stringency (Hu and Ma, 2006). Microsoft Excel program was used to merge the overlapping significant genes from two transgenic generations. Annotations from Affymetrix for significant genes were checked in NCBI public database using Blastx program (Altschul et al., 1997) and in TIGR Rice Genome Annotation version 4.0 (Yuan et al., 2005) and corrected if necessary.

Data table header descriptions
VALUE average intensity of probe intensities for that gene from microarray (higher intensity = higher gene expression)
ABS_CALL whether the Affymetrix data extraction software detected the mRNA for that gene or not (if detected, then P for Present; if not detected, then A for Absent; M is Marginal for borderline detection)
DETECTION P-VALUE P-value for confidence in ABS_CALL (from Affymetrix data extraction software)
