Tissue-specific expression of TIP2;2-GFP in roots of Arabidopsis seedlings. Fluorescence (a,c,e,g,i) and transmitted light (b,d,f,h,j) images of roots of transgenic Col plants expressing a TIP2;2-GFP fusion protein driven by its own promoter. Seedlings were grown for 6 days (a–h) or 11 days (i,j) in a 16 h light/8 h dark cycle. (a–h) Mature region (a,b), border region of the elongation to mature zones (c,d), root tip (e,f), and lateral root primordium (g,h) of the primary root. (i,j) Growing lateral roots with bright fluorescence. co, cortical cell; en, endodermal cell; ep, epidermal cell; lp, lateral root primordium; lr, lateral root; mr, main root; p, pericycle cell; rm, root apical meristem. Bars, 50 µm.
