Fig. 6

Histochemical and quantitative fluorimetric analysis of different GmRD26 promoter deletion constructs in transgenic A. thaliana plants. The stress treatments for GUS activity analysis was performed on 4-week-old A. thaliana plants under 12 h treatments with ABA, PEG, or drought. (A) Histochemical localization of GUS activity in transgenic A. thaliana plants harboring promoter-GUS constructs. (B) The quantitative fluorimetric assay for GUS activity was carried out in three replicates. The soybean promoter and its modules were compared with the pAtRD29 and wild type plants. Control samples consisted of untreated plants. Bars indicate standard error and different lowercase letters indicate significant differences at P < 0.05 on Tukey’s Test. The data shown are representative of three independent lines (n = 3)
