Expression data from PEG treated roots

We study differences in gene expression between 5% PEG treated and control plants’ roots. We used microarrays to detail the global program of gene expression underlying morphological and developmental changes droved by water limitation mimicked by PEG treatment.treated Poplar roots from PEG treated and untreated from in vitro condition was selected for RNA extraction and hybridization on Affymetrix microarrays. Roots were sampled at 6, 24, 48, 96 and 504h after transfer to control and 5% PEG media and RNA was extracted.
