Fig 4. EMP21 is a mitochondrion-targeted PPR-DYW protein.

Fig 4

(A) Protein structure of EMP21. EMP21 contains 11 PPR motifs, E1, E2, and DYW motifs. The Mu insertions are marked by triangles. (B) Non-rooted phylogenetic tree of EMP21 orthologs. (C) Subcellular localization of EMP21 in Arabidopsis protoplasts. The N-terminal 511 amino acid residues of EMP21 fused with green fluorescence protein (EMP21N511:GFP) was stably expressed in Arabidopsis. Florescence signals were observed by confocal microscope ZEISS LSM 880. The mitochondria were stained by MitoTracker Red. DIC, differential interference contrast. Bar = 10 μm.
