Arabidopsis mutants with constitutive defense activation are deficient in ROS signaling. a, Morphology of three weeks old Arabidopsis constitutive defense/lesion mimic mutants dnd1, cim7 (constitutive immunity 7), cim13 (constitutive immunity 13), lht1 (lysine histidine transporter1) and siz1-2 (scale bar 1 cm). b, Relative expression of marker genes in clear air and after two hours of 350 nL L-1 O3 were analyzed with qPCR in constitutive defense/lesion mimic mutants and wildtype. Values are the mean ± SD of four biological replicates. Statistical significance (P < 0.05) was calculated on log2 transformed data by Two-way ANOVA with Tukey-test. (a, b, c represent comparison of different genotypes in clean air; A, B, C represent comparison of different genotypes in O3 treatment; * and n.s represent comparison between clean air and O3 treatment in each genotype). bHLH(At5g56690): basic helix-loop-helix transcription factor; CML37: CALMODULIN LIKE 37; LOX4: LIPOXYGENASE 4; PAD3: PHYTOALEXIN DEFICIENT 3; PLA2A: PHOSPHOLIPASE A 2A; PR1: PATHOGENESIS-RELATED GENE 1; SAG21: SENESCENCE-ASSOCIATED GENE 21; WRKY40: WRKY DNA-BINDING PROTEIN 40; WRKY75: WRKY DNA-BINDING PROTEIN 75; ZAT10: SALT TOLERANCE ZINC FINGER 10; ZAT12: SALT TOLERANCE ZINC FINGER 12.
