Figure 2: Analysis of PR1, MPK1, and TGA1 transcript accumulation in Arabidopsis leaves treated with defense response inducers only by qRT-PCR (2ΔΔCT method), 3 and 7 days post-inoculation application (dpi). A) PR1, plants treated with SA only (SA, 0.5 mM), and with SA plus virus (SA+T), inoculated only with virus (T+), sprayed with water only (T-). B) PR1; C) MPK1: D) TGA1. SA, salicylic acid, 0.5 mM; PE, hydrogen peroxide, 3 mM; K, NPK-oligosaccharin 450 μL /200 mL, T+, TuMV-infected plant with no inducer added.
