SlSWEET15 localized on the plasma membrane in leaf cells. A, Green fluorescence in Arabidopsis protoplast expressing SlSWEET15–GFP fusion proteins. Asterisks indicate chloroplast autofluorescence (red), lining inside of the plasma membrane. B, Green and red fluorescence were shown in Arabidopsis protoplasts expressing SlSWEET15–GFP fusion proteins and AtPIP2A–RFP fusions, indicating localization to the plasma membrane. C, Confocal images of N. benthamiana epidermal leaf cells transiently expressing SlSWEET15–GFP fusions. Enlarged details were shown in insets. All images are single focal planes. Representative pictures were derived from three independent experiments, containing at least three biological samples. Bar = 10 µm.
