From: The Arabidopsis translocator protein (AtTSPO) is regulated at multiple levels in response to salt stress and perturbations in tetrapyrrole metabolism

Figure 6

At TSPO has different sub-cellular location depending on the translational start site used. Confocal images of OxM1TSPO:eGFP (A-C), OxM21TSPO:eGFP (D-F) and OxM42TSPO:eGFP (G-I) localization. OxM1TSPO:eGFP localizes in the ER and vesicles of unknown function in the root (A), hypocotyl (B) and cotyledon (C). OxM21TSPO:eGFP localizes in the mitochondria of root (D), hypocotyl (E) and cotyledon (F). OxM42TSPO:eGFP show mitochondria localization in root (G), hypocotyls (H) and cotyledons (I). GFP fluorescence is represented by green and chlorophyll auto fluorescence in red. The samples were incubated with Mitotracker to identify mitochondria (see Additional file 3). Homozygous transgenic plants harboring 35S-TSPO:eGFP in wild-type background were used for the analysis. Scale bars = 50 μm.
