Structural rearrangements and large deletions in S. conica mtpt. (A) Gray connections indicate stretches of homology between two different mitochondrial chromosomes and a contiguous region in the plastid genome. Plastid gene names followed by “(C)” are found on the complementary strand. Only mtpt fragments of at least 200 bp in length are shown, but adjacent small fragments extend the boundaries to positions 10,764 and 91,440 in the plastid genome and mitochondrial chromosome 2, respectively. The plastid gene map was generated with OGDRAW v1.2 (Lohse et al. 2007). (B) Alignments show representative examples of microhomology in the plastid sequences that correspond to the mtpt deletion breakpoints. Numbering (1–4) corresponds to the deletions labeled in part (A).
