As reported above, in the absence of pathogen infection, Ta SC1 alone induced a consistent expression of almost all the targeted defenses (2.44–13.03 for LOX9, PR2, GST1, PAL, and STS), suggesting that Ta SC1 may act as a priming stimulus for Tempranillo cultivar, but in a lesser extent when combined with Bs PTA-271 (1.84–9.66). This evidence concerns the gene STS and infection.
