Fig. 3: Visualization of eYGFPuv in the early stages of tissue culture-based plant transformation.

A Visualization of eYGFPuv during callus and shoot stage of tobacco transformation under UV light, two-week and four-week post transformation, respectively. Photos were taken in petri dishes without the lids. B Visualization of eYGFPuv during callus and shoot stage of poplar transformation under UV light, four-week and six-week post transformation, respectively. Photos were taken in petri dishes with the lids. C Visualization of eYGFPuv during callus and shoot stage of citrus transformation under UV light, five-week and eight-week post transformation, respectively. Photos were taken in petri dishes without the lids. (White arrows indicate eYGFPuv-expressing events; Scale bar, 1 cm)
