'All genes' means all genes represented in the Affymetrix ATH1 chips. "GC_up" and "GC_down" represent ABA-induced and ABA-repressed genes in guard cells, respectively. "LF_up" and "LF_down" mean ABA-induced and ABA-repressed genes in leaves, respectively. The numbers in brackets in the header denote the total number of ABA-regulated genes in the corresponding category. P-values smaller than 0.01 are marked in bold.
