qRT-PCR analysis of relative transcript abundance of the three TFs (e.g., T14, T15 and T24) in their corresponding VIGS lines as compared to those in tobacco wild type (WT) and VIGS line with empty pTRV2 (V2) plants. The three TFs were induced 2 h after oxalic acid (OA) treatment. The Nbactin gene was used as the house-keeping control. Gene codes refer to those indicated in Additional file 3: Table S2. Data were statistically analyzed as outlined by Gomez and Gomez [28] and multiple comparisons were made following the Duncan’s New Multiple Range test [29]
