Induction of WRKY Genes by SAR Inducers and NPR1
Plotted here are log2-transformed microarray data normalized by the GeneSpring package, showing the expression levels of six WRKY genes 0, 8, and 24 h after BTH treatment in WT (NPR1 +) and npr1 mutant (NPR1 −). The expression levels of WRKY59 and WRKY66 were too low to be detected under these conditions. Error bars represent standard deviations (SDs).
