Fig. 2: GUS expression triggered by different SCBV promoters in transgenic Arabidopsis plants.

a RT-qPCR assay of GUS gene, b Fluorometric GUS activity assay. Values are the means (±standard errors) of three T3 transgenic lines and three biological replicates. For each assay, mean values with the same letter are not significantly different at P = 0.05 according to Duncan’s multiple range test.
