Effect of HSP terminator on transient GFP expression at 3 days post-agroinfiltration. Total soluble proteins were extracted from agroinfiltrated plant leaves with pBYR2HS-EGFP or pBYR2fp-EGFP. Coomassie Brilliant Blue (CBB) staining and immunoblot analysis with anti-GFP antibodies were performed by using agroinfiltrated leaves of N. benthamiana (A), lettuce (B), eggplants (C), tomatoes (D), hot peppers, and roses (E). The numbers at the top of the gels indicate different samples taken from different leaves from different plants. NT indicates non-transfected plants. The amount of protein was measured according to band intensity from CBB staining gel using ImageJ software. Arrowheads indicate bands corresponding to GFP protein. The band clearly seen at 55 kDa in a CBB staining gel is corresponding to large subunit of Rubisco. Data represent the means ± SD (n = 3 to 4). Significance was determined using unpaired Student’s t tests (*p < 0.05). Full-length gels and full-length blots are presented in Supplementary Figures S1 and S2.
