plantStressCounts {DAAGbio}R Documentation

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.
