From: In vivo functional analysis of a nuclear restorer PPR protein
Depiction of PPR-A, the base construct wtRfo and different derived genetic contructs. PPR repeats are indicated by ovals, non-PPR domains by rectangles of equal height. Portions of the construct composed of PPR-A sequences are crimson, portions from Rfo sequences are blue. The domains with the 4 amino acid deletion in PPR-A and the Rfo? construct lacks a black outline used to designate true PPR repeats. Non-protein coding regions are represented by lines. Construct numbers correspond to those of Additional file 6: Generation of genetic constructs. Construct 2 was omitted since it is a utility clone carrying only the Rfo promoter region with flanking Sal1 and Xho1 sites (Additional file 5: Figure S4).
