Subcellular Localization of Gle1.
The GFP signal in the nuclear envelope is marked with arrowheads.
(A) A DNA construct encoding GFP-Gle1 under the control of the cauliflower mosaic virus 35S promoter was expressed in N. benthamiana leaves via agroinfiltration. GFP fluorescence was observed by confocal microscopy.
(B) Tobacco BY-2 cells were fixed and doubled-labeled with anti-Gle1 antibodies (red) and anti-α-tubulin antibodies (green) and stained with DAPI for confocal microscopy.
(C) GFP fluorescence in root cells of the Arabidopsis transgenic plants designated ProGle1:GFP-Gle1, which express GFP-Gle1 under the endogenous Gle1 promoter, was observed by confocal microscopy. Two independent transgenic lines (lines #13 and #21) were examined for this analysis.
