Schematic map of the second copy of 17-kb repeat in CMS-Sa and CMS-Sb. Coding genes are indicated by boxes of purple color. The mtpt sequence and its homolog in chloroplast genome are labeled in green color. The eliminated 3.3-kb sequence in CMS-Sb is labeled in gray color. The putative nad1 transcripts were cleaved at the sites adjacent to trnP to generate the 5′ end of precursor. 3′ end of nad1 precursor were tested at the sites adjacent to mtpt sequence
