Figure 2.

The genetic organization of recombined mtDNA in hybrids. For simpler comparison, the circular genomes, exported from Vector NTI, were aligned at the beginning of the large rRNA subunit (rnl). Genes are marked with colored rectangles with arrows or lines, and origins of replication are marked with black circles. The RNA of the rnpB gene and tRNA genes are indicated by thin lines. Introns are marked with white rectangles. Gene nomenclature follows the rules described in GOBASE (atp for ATP synthetase subunits; cox for cytochrome oxidase subunits; cob for cytochrome b; rns for small rRNA ribosomal subunit; rnl for large rRNA ribosomal subunit; T2, C, H, etc. for particular tRNA coding genes; rps3 for ribosomal protein; and rnpB for the RNA subunit of RNase P). Sections originating from S. cerevisiae are marked in red, and those originating from S. paradoxus are in blue. Introns and free standing ORFs known as mobile, in S. cerevisiae are marked in black³⁵. Their homologs in S. paradoxus are marked in yellow. Sizes are given on the bottom line in kbp. GenBank accession numbers MW367979, JQ862335, MW367976, MW367977.
