Differential expression analysis of genes linked to tomato defence mechanism. A: The RAP-2/ACTIN genes fold change, B: the XET-2/ACTIN genes fold change, and C: the ACS-2/ACTIN genes fold change after plant treatment with GAS-NPs and SA-NPs at two different concentrations (1Â ml/L and 3Â ml/L) as well as control, Actin gene, the most stable reference gene, was used as an internal reference gene
