Mimic effects of GhLMM dosage on leaf phenotype by spraying LA. A, Leaf phenotype of W0 plants after being sprayed with different concentrations of LA solutions. Treatment with >20 mm LA solution leads to clear lesions on leaves. B, The content of ALA, H2O2, and SA was increased in W0 plants treated with different concentrations of LA solutions. C, PR gene expressions were up-regulated in W0 plants after LA treatment. At least three biological replicates were performed in each experiment. *P < 0.05 and **P < 0.01 (Student’s t test).
