Subcellular localization of AtOxR-GFP. A Expression of GFP protein (a, b) and AtOxR-GFP fusion constructs (c~f) in yeast cells. Scale bars = 5 μm. B Expression of GFP protein (a, b) and AtOxR-GFP fusion constructs (c~f) in A. thaliana root cells. The GFP column shows the signal detected in the green channel; the ER Tracker column shows the signal detected in the red channel; the GFP+ ER Tracker column corresponds to the merging of the green and red channels, in which yellow represents the superposition of green and red. DIC: differential interference contrast. Scale bars = 20 μm
