DR5::GUS reporter gene expression in leaf primordia exposed to 2,4-D. First rosette leaf primordia were incubated in culture medium containing 1 μm 2,4-D for 5 h, followed by histochemical detection of GUS activity. Age in DAG: A, 2; B, 3; C, 4. Scale bars = 50 μm in A and B, 100 μm in C. DIC optics.
