GUS activity assays of transgenic Arabidopsis AtACBP3pro::GUS plants following wounding. (A) Four-week-old AtACBP3pro::GUS transgenic plants were wounded with a pair of forceps and harvested at 1, 2, 3, and 4 h post wounding (hpw) for quantitative GUS activity measurements. Vector (pBI101.3)-transformed plants were analysed at 1 hpw and served as a negative control, while unwounded AtACBP3pro::GUS plants were used as a baseline control. “**” indicates statistically significant difference (P < 0.01, n = 3 by Student's t-test) in comparison to unwounded samples collected at the same time point. Error bars represent standard deviations. (B) A representation of histochemical staining of wounded 4-week-old leaves from AtACBP3pro::GUS and vector (pBI101.3)-transformed (VC) Arabidopsis. These experiments were repeated twice with consistent results. Scale bars = 0.8 cm.
