Visualization of ALA10 promoter-GUS expression in 5-day-old A. thaliana seedlings after 12 h (a,b) or 40 min (c–e) of tissue staining. (a) Aerial tissues. (b) Guard cells of the cotyledons. (c) Full view of seedling. (d) Root tip. (e) Magnification of root tip in (d). Arrows indicate the position of unstained guard cells. Scale bars, (a,c) 0.5 mm; (b,e), 0.05 mm; (d), 0.1 mm.
