(A) Determination of luciferase reporter gene activity of in vitro ‘Williams’ banana plants transformed with the construct containing P35S::luc2. Exposure time was 3 min in total darkness; the photo was captured using the Stella 3200 equipment camera (Raytest, Straubenhardt, Germany). Luciferin dissolved in water (500 µm) was applied to in vitro plants. ‘Live’ indicates luciferase enzyme activity detected under conditions of total darkness. (B) Luciferase activity in N. tabacum leaves agroinfiltrated for the luciferase reporter gene expression fused to the CaMV 35S promoter (P35S::luc2).
