Negative regulation of pathogen resistance by CIPK6 was dependent on salicylic acid (SA). (A) Col-0, cipk6, cipk6sid2-1, and sid2-1 leaves were manually infiltrated with MgCl2 and Pst DC3000 (EV) or Pst DC3000 (ΔhrcC). Total SA was measured at 9 hpi. (B, C) The same plant lines as above were infiltrated with MgCl2 and Pst DC3000 (AvrRps4/AvrRpm1). Total and free SA was measured at 9 hpi. (D) Bacterial growth was assessed at 3 dpi in Col-0, cipk6, eds1-2, cipk6eds1-2, sid2-1, and cipk6sid2-1 plants and was expressed as the log cfu/mg fresh weight. The asterisks indicate a significant difference following two-way ANOVA (α=0.05).
