Fig. 7From: Identification of NHXs in Gossypium species and the positive role of GhNHX1 in salt toleranceSubcellular localization of GhNHX1A/D. GFP-GhNHX1A and GFP-GhNHX1D were co-transformed with vacuolar marker δ-TIP-RFP into the Arabidopsis protoplasts. Images were observed with confocal laser scanning microscope. GFP coexpressed with δ-TIP-RFP was used as positive control. The cell nuclei were marked with white arrows. Scale bar = 5 μmBack to article page
