Figure 2. — PZF:GFP expression in Arabidopsis roots. (A) Root tips from a GFP-transformant (GFP) and an untransformed (control) plant under white light and (B) under blue excitation. Only the transformant shows green fluorescence in the meristematic cells. (C) Confocal image of a root tip expressing 180:GFP, showing GFP-fluorescent nuclei. (D) Magnification of cells shown in (C) reveals up to 10 brightly fluorescing spots per nucleus. (E) In comparison, the control GFP construct without PZF domain shows a diffuse fluorescence throughout the nucleus. Scale bar = 5 microns. (C–E) are Z stacks of optical sections.
