The relative expression of PR1 and PDF1.2 in different mutants detected by q-PCR.

Mock + TMV or COS + TMV means Arabidopsis pretreated with water or 50 mg/L COS, then inoculated with TMV by gently rubbing the leaf surface using Carborundum (silicon carbide). Mock means pretreated Arabidopsis with water, then inoculated with PBS. (A) The expression of PR1 and PDF1.2 in WT. (B) The expression of PR1 and PDF1.2 in NahG mutant. (C) The expression of PR1 and PDF1.2 in jar1 mutant. All data were measured using actin8 as reference gene. Values were presented as means ± SD from three independent measurements. Asterisks indicate significant differences (**P < 0.01; ***P < 0.001).
