Fig. 5From: A novel Sugarcane bacilliform virus promoter confers gene expression preferentially in the vascular bundle and storage parenchyma of the sugarcane culmThe 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.
