Fig. 3.

Mitochondrial genome of the cybrid Nt(+Hn). Scale maps of the seven contigs that comprise the 705,036 bp mitochondrial genome of the cybrid. The wide orange and blue boxes located on the cybrid genome indicate regions inferred to derive from either the Nicotiana tabacum (Nt) or Hyoscyamus niger (Hn) parents, respectively. The thinner, orange and blue boxes to the right of the cybrid contig maps indicate regions shared (as defined by Blast hits) with the mitochondrial genomes of Nt or Hn, respectively. Numbers to the right of the blast hits designate the 35 intergenomic homologous recombination events detected in the cybrid (also see Table 3). Crossing and parallel lines mark inferred sites of crossover (CO) and gene conversion (GC) events, respectively. The cybrid contig maps show full-length genes, repeats ≥1 kb in length (purple boxes labeled ‘R’, followed by the repeat lengths in kb), and chloroplast-derived regions >400 bp in length (green boxes labeled ‘cp-like’). Genes marked on different sides of the central vertical lines are transcribed from opposite strands of the genome.
