The OpsDHN1 histidine-rich motif is required for its nuclear subcellular localization. (A) Schematic representation of the pMDC43-OpsDHN1-ΔHis construct. (B) Schematic representation of BiFC pYFN43- and pYFC43- OpsDHN1-ΔHis vectors. (C) Cytoplasm localization of GFP::OpsDHN1-ΔHis translational fusion in N. benthamiana leaves. White arrowheads indicate cytosolic and nuclear compartments. (D) BiFC assay of OpsDHN1-ΔHis version. Transient fluorescent expression was analyzed by laser-scanning confocal microscopy. From left to right: the GFP and DAPI fluorescence spectrum, bright field, chlorophyll fluorescence and overlay signals. The S-segment and K-segments are depicted as dark-gray box and black boxes, respectively. The deleted histidine-rich motif is represented by an open triangle. The scale bar corresponds to 10 μm.
