Figure 3

Structure of large repeated sequences in the Silene latifolia mitochondrial genome. The genome contains a 1362 bp direct repeat present in 6 copies (white boxes). Additional repeat extensions (gray boxes) of varying length are shared by some but not all of the regions that flank the repeat. Shorter repeat extensions are identical in sequence to the initial portions of longer repeat extensions, with the exception of the "left" flanking regions next to repeat copies 4 and 5, which share a short 12 bp sequence (solid black boxes) that is unique relative to the other flanking sequences. Single copy sequences flanking the repeats are shown by thin black lines. The red bars indicate the location of probes used in Southern blot hybridizations (Figure 4). The values on the left and right side indicate the length of the respective repeat extensions. The order of the repeat copies and their flanking sequences corresponds to the genome conformation shown in Figure 2.
