Subcellular localization of HvSUT2, AtSUT4, and AtSUC2 by transient expression of GFP fusion proteins in onion epidermal cells and Arabidopsis epidermal cells. Cell walls and nuclei of Arabidopsis were stained in red with propidium iodide. Nuclei are indicated by arrowheads. A to E, Tonoplast localization of HvSUT2 in onion epidermal cells (A–C) and Arabidopsis epidermal cells (D and E). Fluorescence of the HvSUT2-GFP fusion protein in onion epidermal cells (A) and transmission picture (C) of the same cell. The tonoplast is located in the internal side of the cytoplasm including the nucleus as shown in the overlay of the detail pictures (B and E). F to J, Localization of the AtSUT4-GFP fusion protein at the tonoplast, transiently expressed in onion epidermal cells (F–H) and Arabidopsis epidermal cells (I and J). As shown in detail pictures (G and J), the green fluorescent tonoplast surrounds the nucleus. K and L, Plasma membrane localization of AtSUC2-GFP in Arabidopsis epidermal cells.
