Colocalization analysis of cis-regulatory elements in hsfa2 and npr1 mutants and models of crosstalk. A and B, Colocalization analysis of predicted cis-regulatory elements for H₂O₂ responses at the indicated time points and the heat shock response (A) or response to SA (B) were applied to wild type and hsfa2 (A) or npr1 (B) mutants. WT, wild type. C and D, The vertical axis shows the number of colocalized loci. Models for crosstalk between the H₂O₂- and HSFA2-associated heat stress responses (C) and NPR1-associated SA and ABA responses (D), based on colocalization analysis (D also includes the results of Figs. 2 and 3). See Supplemental Table S12 for accession numbers of microarray data of hsfa2 under heat shock stress and npr1 with SA treatment using promoter prediction.
