A total of 104 genes were identified with significant Psm-induced upregulation in distal leaves of sid2 but not Col-0 plants (Figure 3A). The genes were listed in descending order according to their sid2 P/M ratios. The 10 genes with highest P/M ratios in sid2 and all genes significantly downregulated in Col-0 (SAR⁻ genes) from this group are depicted. The position of each gene in the list is indicated. Asterisks indicate significant changes between Psm and mock treatments (FDR < 0.01).
