EMP25 is a mitochondrion-localized P-type PPR protein. (A) Schematic diagram of the EMP25 protein. (B) Subcellular localization of EMP25. The N-terminus (223 amino acids) of EMP25 was fused with the green fluorescence protein (GFP). The EMP25N223aa–GFP fusion was transiently expressed in tobacco leaf epidermal cells and the signal was detected by confocal fluorescent microscopy. Mitochondria were detected with MitoTracker. DIC, differential interference contrast. Scale bar = 10 μm.
