The data in Figure 2 are presented on non-logarithmic y-axis. (A) Amount of mRNA of each gene in untreated control leaves and wounded leaves harvested 80 min after wounding. (B) Amount of mRNA of each gene in leaves treated with 0.05% Tween 20 (mock) or 100 µM MeJA for 80 min. All mRNA levels are expressed as values relative to the amount of DAD1 mRNA in wounded leaves, defined as 1. Error bars denote SE.

Wounded leaves were harvested from 2-5 plants at 90 min after wounding and JA accumulated in the leaves were extracted and measured. The mutants aos (SALK_017756), opr3 (opr3-11), and double mutants acx1/5 (SALK_041464 × SALK_009998) were compared to wild-type Col-0 plants. nd, not detected.

(A) opr3-11 generated by fast neutron irradiation. (B) coi1-51 generated by ethyl methanesulfonate treatment. Untranslated regions, coding regions, and introns are represented by grey boxes, black boxes, and solid lines, respectively. Nucleotide and amino acid sequences around the mutation site are shown. Substituted nucleotide and amino acid residues are indicated by red. Numbers represent the positions of amino acid residues counted from the N-terminal methionine residue.

(A) Heatmap matrix representing expression levels of DAD1, DAD1-like lipases, and JA-related genes upon wounding in various JA-related mutants. Expression levels relative to that in wild type were color coded. nd, no data. (B) Pearson’s correlation coefficient table for DAD1 and its related genes showing their expression similarity. Relative expression levels indicated in (A) were used for calculation. P-values of t-test for correlation significances are also shown. Values are colored if p < 0.05 (red) and if 0.05 ≤ p < 0.07 (blue). Note that the correlation coefficient between DAD1 and DALL1 was negative.
