organism: Arabidopsis thaliana
description: This sample consists of cDNA tags that query the mRNA-poly(A) junction, prepared using RNA isolated from dry Arabidopsis seeds.  cDNA was prepared and the desired tags made as described in Wu et al. (submitted).  These paired-end tags are bar-coded and mixed with other samples in the various experiments.  Wild-type leaf tags have the following codes:  5' reads begin with either CCCATG or CCACGT, and 3' reads begin with the sequence NNNGCTTTT (for tags in the AHQL2 sample) or NNNGGTTTT (for tags in the AHBD2 sample).  These codes can be used to extract seed tags for analysis.
