DYW2 and NUWA are members of the PPR family. (A) DYW2. (B) NUWA. Schematic structures of the loci and the proteins. Predicted targeting peptide (TP, gray box), S (red), L (orange), P (yellow), DYW (blue), and coiled-coil region (C-C, green) domains are labeled on the protein sequence. The targeting peptide was predicted using the TargetP software at www.cbs.dtu.dk/services/TargetP/ for plant organisms using no cutoffs. S, L, P, and DYW domains were located according to the PPR Gene Database (11) and using the TPRpred software at https://toolkit.tuebingen.mpg.de/#/tools/tprpred [(P), light yellow]. Sequence-verified locations of the T-DNA insertions used in this study are indicated (+1 is the transcription start).
