NaKR1 Is Expressed in Companion Cells, and NaKR1-GFP Is Phloem Mobile.

Confocal images (except in [C]) of Arabidopsis tissue stained briefly with propidium iodide.

(A) NaKR1pro:histone2B-GFP localization in companion cell nuclei of Col-0 primary root.

(B) NaKR1pro:histone2B-GFP localization in the proximal meristem region of the primary root meristem.

(C) Epifluorescence image of NaKR1pro:histone2B-GFP expression in Col-0 root. Aniline blue staining shows sieve plate (indicated by arrow) of the adjacent sieve element.

(D) NaKR1pro:NaKR1-GFP expression in a mature, complemented nakr1-1 root.

(E) NaKR1pro:NaKR1-GFP fluorescence in the proximal meristem region of a primary root of complemented nakr1-1. Inset is magnified meristem region.

(F) NaKR1pro:NaKR1-GFP expression in the lateral root of complemented nakr1-1.

(G) Free GFP expressed using the SUC2 promoter showing fluorescence in the mature primary root of Col-0.

(H) Expression of free GFP under control of the SUC2 promoter in a primary root meristem of Col-0. Scale bars indicate 100 μm except for C in which the bar is 10 μm.
