Display of citrus differentially expressed genes (DEGs) response to the DSF/Rpf-mediated Xanthomonas citri subsp. citri infection that are involved in different metabolic pathways (a) or biotic/abiotic stress responses (b). The log2 fold change of gene expression (∆rpfF -inoculated plants versus wild type Xanthomonas citri subsp. citri -inoculated plants) was analyzed using MapMan. Each square represents an individual gene within a category. Small squares colored in red and blue represent genes in infected plants that were up- and down-regulated by DSF/Rpf – mediated Xac infection, respectively. A false color scale was used and all the values were given on a log2 scale. The color saturates at a 4-fold change (i.e. log2 ratio = 2 or − 2). A significant downregulation was observed for many genes that are involved in photosynthesis, secondary metabolism, or response to biotic stress including genes for signaling, hormone metabolisms, and plant defense responses
