Fig. 5

The SCBV21 promoter directs GUS gene expression in the sugarcane culm vasculature and storage parenchyma. GUS activity was analyzed histochemically in transverse sections of a, b transgenic sugarcane culms carrying SCBV21:GUS, and in c nontransformed sugarcane culms. x, xylem; px, protoxylem; mx, metaxylem; p, phloem; s, sclerenchyma; spa, storage parenchyma. Scale bar 50 μm
