ROSMETER analysis of various abiotic stresses. The expression data of Arabidopsis plants exposed to various abiotic stress conditions (Kilian et al., 2007) are from GEO data sets (http://www.ncbi.nlm.nih.gov/gds/). They include salt (GSE5623), osmotic (GSE5622), cold (GSE5621), UV-B (GSE5626), heat (GSE5628), and drought (GSE5624) stresses. Only data from shoot tissue were analyzed. For each experiment, fold change values were normalized to the control series (GSE5620). The indices are listed on the abscissa, and the abiotic stress experiments are listed on the ordinate and clustered according to the similarity of their profiles represented in clusters A to G.
