| Title |
Microarray analysis of rice plants exposed to jasmonic acid (JA) |
| Platform organism |
Oryza sativa Japonica Group |
| Sample organism |
Oryza sativa |
| Experiment type |
Expression profiling by array
|
| Summary |
In this study, integrated transcriptomics and proteomics approaches were applied to investigate the molecular responses of JA in the shoots of 7-days old rice (cv. Nipponbare) seedlings exposed to 5 micromolar JA for a period of 7 days. Based on the morphological alteration of JA-exposed rice seedlings, transcript profiling of rice genes was performed in seedlings using rice DNA microarray chip, and proteomics by 2-DGE. This systematic survey showed that JA triggers a chain reaction of altered gene and protein expressions involved in multiple cellular processes in rice growth and development and defense.

| Overall design |
An in vivo 7-days-old rice seedling model system was used, where whole seedlings were used for exposure to the JA (5 micromolar). Dye-swap or reverse labeling with Cy3 and Cy5 dyes procedure was applied followed by hybridization and wash processes, and the hybridized microarrays (G4138A) were scanned using a GenePix microarray scanner followed by the Gene Pix 4000 analysis application program for image analysis and data extraction processes. The GeneSpring Ver. 4 software was used for normalization.
