In vivo localization of GFP-AtRanBPM in Arabidopsis cells and seedlings. A- Localization of GFP-AtRanBPM in Arabidopsis suspension culture. The protein is localized in the cytoplasm and in the perinuclear area. Weaker signal is present in nuclei. B- Root tip of 8 days old Arabidopsis plant. Weak cytoplasmic signal for GFP-AtRanBPM is enriched in the perinuclear area. C- Cytoplasmic and perinuclear localization of GFP-AtRanBPM in differentiated cells of root. Bars = 10 μm.
