The GO annotation of genes in italic text is suggestive of a role in ABA response. The GO annotation of genes in bold type is suggestive of a role in abiotic stress response. Genes were classified by their functional category using MIPS Functional Catalog (FunCat) Database (http://mips.gsf.de/projects/funcat): 1, metabolism; 2, transcription; 3, translation/posttranslation (protein folding, modification, or destination); 4, binding; 5, transport; 6, signal transduction; 7, abiotic stress response; 8, interaction with the environment; 9, ABA response; and 0, unclassified/other.

P values from a two-way ANOVA between log₂ RMA-processed expression values were corrected using the method of Benjamini and Hochberg. A significance level of α = 0.01 was used as the cutoff.
