HUP26 promoter assays upon various stresses. (a) Schematic representation of the HUP26pro-GUS constructs used to GUS. Construct of the HUP26 promoter was fused to the GUS reporter gene in the vector pCAMBIA1301. Each cis-acting regulatory elements (CAREs) were predicted by PlantCARE tool. (b) The promoter activity of HUP26 was highly induced by oxidative stress treatment. HUP26pro-GUS transgenic plant shows normal expression of vascular tissue and root tip region. (c) After 24 h upon Pst DC3000 (dipping inoculation with 1 × 10⁸ CFU/ml) or 6 h upon 1 mM SA spraying treatment, GUS activity of HUP26 promoter was highly induced in the leaf
