Matrix holding mRNA counts
Description
Three treatments (3 samples each) were applied to Arabidopsis plants. RNA-Seq technology was used to determine messenger RNA (mRNA) counts. These were processed to remove counts for sequences that could not be identified as corresponding to a gene.
Usage
data("plantStressCounts")Format
The matrix plantStressCounts has 28775 rows,
and 9 columns. Rows have the nondescript names
"Gene1" "Gene2" "Gene3" "Gene4" ... . Columns are
named "CTL1", "CTL2", "CTL3", "Light1", "Light2", "Light3",
"Drought1", "Drought2", "Drought3"
Details
The treatments were:
- Control
Plants were grown under normal light and watering conditions
- Light stress
One hour of continuous exposure to light at ten times the level that the plants are normally grown under
- Drought stress
Nine days without water, causing wilting of the leaves
The interest is in how light and drought stress affect gene expression to produce proteins.
