Sequence analysis and subcellular localization of the WSL4 protein. (A) WSL4 protein has 12 PPR motifs, whereas the wsl4 mutant protein contains only 9. (B) The 12 PPR motifs of WSL4. (C) Transient expression of WSL4–GFP and wsl4–GFP fusion proteins in rice protoplasts. (D) Colocalization of WSL4 (GFP) and PEND (CFP) within chloroplast nucleoids. GFP, GFP signals of WSL4 fusions; CFP, CFP signals of chloroplast nucleoid marker PEND; Auto, Chl autofluorescence; Merged, Merged images of GFP, CFP, and Auto. Bars, 5 μm.
