Expression profile of histone chaperones in Arabidopsis and rice under various biotic stress conditions. Heat maps show the microarray-based expression pattern of histone chaperones from Arabidopsis (A) and rice (B) under conditions of infection with different pathogens as indicated at the top of the heat map. Color bars at the bottom of each of the heat maps show the corresponding scale for log2 fold change in expression. Heat maps were generated using hierarchical clustering for which weighted average linkage method and Pearson correlation distance metric were used. Genes which showed more than two-fold up- or down-regulation {log2(fold change) ≥ 1, or log2(fold change) ≤ -1, respectively; Student’s t-test p < 0.05} were considered to be showing significant differential regulation of expression in the respective conditions.
