| Title |
Laser capture microdissected (LCM) whole seeds at the linear-cotyledon stage, biological replicate 1 |
| Sample type |
RNA |
| |
|
| Source name |
Arabidopsis linear-cotyledon stage whole seeds captured by LCM
|
| Organism |
Arabidopsis thaliana |
| Characteristics |
genotype: Ws-0
|
| Treatment protocol |
Siliques between 1.6 and 1.9 cm long containing linear-cotyledon stage seeds were collected from 38-46 day old plants. Siliques were sub-divided and fixed in 3:1 (v/v) ethanol to acetic acid and embedded in paraffin. Microdissection of compartments was carried out on sections using a Leica LMD6000 system.
|
| Growth protocol |
Plants were grown in a Conviron chamber under continuous light with fluorescent lamps at 20°C and 50% - 70% relative humidity.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted using the RNaqueous Micro-Kit (Ambion, Austin, TX) using a modified protocol incorporating an on-column DNase treatment (Qiagen RNase-Free DNase Set) during column washes.
|
| Label |
biotin
|
| Label protocol |
2 to 5 ng of total RNA was amplified using the WT-Ovation Pico RNA Amplification System (NuGEN, San Carlos, CA). cDNAs were fragmented and labeled with NuGEN FL-Ovation™ cDNA Biotin Module V2.
|
| |
|
| Hybridization protocol |
Following fragmentation, five micrograms of cDNA was hybridized for 18 hr at 45°C with the GeneChip ATH1 Arabidopsis Genome Array. GeneChips were washed and stained using the EukGE-WS2V4_450 protocol in the Affymetrix Fluidics Station 450.
|
| Scan protocol |
GeneChips were scanned using the Affymetrix GeneChip Scanner 3000 7G System.
|
| Description |
Arabidopsis lcWS4
Whole seeds collected from seeds containing linear-cotyledon embryos 175 (+/- 11) microns in length as determined by median section using the LEICA LMD6000 system for microdissection.
|
| Data processing |
The data were analyzed with the Affymetrix GeneChip Operating system 1.4 (GCOS) using default analysis settings and global scaling as a normalization method. The mean target intensity of each array was set to 500.
