## Arabidopsis RNA-Seq data set

### Description

This dataset was imported from NBPSeq package and the following explanation is verbatim copy of their explanation:

An RNA-Seq dataset from a pilot study of the defense response of Arabidopsis to infection by bacteria. We performed RNA-Seq experiments on three independent biological samples from each of the two treatment groups. The matrix contains the frequencies of RNA-Seq reads mapped to genes in a reference database. Rows correspond to genes and columns correspond to independent biological samples.

### Usage

    data(arab)

### Format

A 26222 by 6 matrix of RNA-Seq read frequencies.

### Details

This dataset was imported from NBPSeq package and the following explanation is verbatim copy of their explanation:

We challenged leaves of Arabidopsis with the defense-eliciting ΔhrcC mutant of Pseudomonas syringae pathovar tomato DC3000. We also infiltrated leaves of Arabidopsis with 10mM MgCl2 as a mock inoculation. RNA was isolated 7 hours after inoculation, enriched for mRNA and prepared for RNA-Seq. We sequenced one replicate per channel on the Illumina Genome Analyzer (http://www.illumina.com). The length of the RNA-Seq reads can vary in length depending on user preference and the sequencing instrument. The dataset used here are derived from a 36-cycle sequencing reaction, that we trimmed to 25mers. We used an in-house computational pipeline to process, align, and assign RNA-Seq reads to genes according to a reference database we developed for Arabidopsis.
