CK2α3 and CK2β3 Affect ER Exit of PT.

(A) Subcellular localization of the PT2-GFP and PT8-GFP fusion proteins. Constructs of 35S-PT2/8-GFP were expressed in rice protoplast cells (control).

(B) to (E) Expression patterns of PT2-GFP and PT8-GFP fusion proteins in cells cotransformed with constructs overexpressing the four CK2 subunits.

(F) to (H) Subcellular localization of PT8-GFP in the epidermal cells of rice roots. Results from 7-d-old transgenic plants transformed with the PT8p-PT8-GFP construct alone (F) or simultaneously with PT8p-PT8-GFP and CK2α3 overexpression (G) or CK2β3 overexpression (H) are shown.

Bars in (A) to (E) = 5 μm; bars in (F) to (H) = 20 μm.
