Fig. 4: Expression of GUS gene driven by promoter PSCBV-YZ2060 in transgenic Arabidopsis plants.

a Plants treated with 10 μM ABA. b Plants treated with 25% PEG6000. Values are the means (±standard errors) of three T3 transgenic lines and three biological replicates. For each treatment and each time point, values that are significantly different at P = 0.05 and P = 0.01 (Student’s T test) are indicated by one and two asterisks, respectively.
