Figure 1

A GFP::ALA1 fusion was transiently expressed in tobacco epidermal cells alone (A) or in the presence of an YFP::HDEL ER-retained marker (B). Green: GFP fluorescence; blue: autofluorescence; magenta: YFP fluorescence; gray: bright field image. Panels on the right show an overlay image. Scale bar: 25 µm.
