RT-PCR analysis of 3 independent col-0/35S:OsRFP-EGFPs T3 transgenic plants (#1, #2, and #3) and the control plant (35S:EGFP). Total RNA was extracted from 14-d-old Arabidopsis seedlings, and first-strand cDNA was synthesized using a cDNA synthesis kit (Takara-Bio, Ohtsu, Japan). Semi-quantitative RT-PCR was conducted using each gene specific primer set. The AtUBC10 (At5g25760) gene was used as an internal PCR control.

The root lengths of each transgenic plant and control plant were photographed after 7 d and analyzed using Image J software. Data represent means ± SDs of 3 independent experiments (n = 30). ‘*’ and ‘**’ indicate significant differences of overexpressing transgenic lines in comparison to the control at p < 0.05 and p < 0.01, respectively (Student’s t -test).
