Figure 8. GFP expression driven by GTTGA and TATTT in the transgenic rice leaves.

(a) GFP fluorescence assay of transgenic rice leaves inoculated with R. solani strain YWK196. Three T₁ lines of each element were used. Bars = 5 mm. (b) Quantitative fluorometric assay of transgenic rice leaves post inoculation with R. solani. The fluorescence value was calculated relative to CK of GTTGA-1. The full-length GRMZM2G315431 promoter and 35S minimum promoter were used as the positive and negative controls, respectively. Error bars indicate the SD (n = 3). Asterisks indicate P < 0.05 (*) in Student’s t test analysis.
