Os EMP5 Is a Mitochondrion-Localized PPR-DYW Protein.
(A) Alignment of maize Zm EMP5 protein with rice ortholog Os EMP5 and sorghum ortholog Sb EMP5 protein.
(B) OsEMP5N372:GFP fusion protein was transient expressed in tobacco epidermal cells. Fluorescence signals from OsEMP5N372:GFP (green) and MitoTracker stained mitochondria (red) were detected by confocal microscopy. DIC, differential interference contrast. Bar = 10 µm.
