Quantitative fluorometric GUS analysis of leaf blade, leaf sheath, stem, and panicles of T0 stable transgenic rice containing each of the three green tissue-specific promoters at the heading stage. The rice plants were grown in the greenhouse at 25–29 °C under 12-h photoperiods (390 μE/m2/s). Stable transgenic rice containing the promoter of CaMV 35S was used as positive control. The fluorometric GUS assay was conducted on at least 10 transgenic lines at the heading stage with the representatives being shown
