Figure 1.
Circular map of the mitochondrial genome of Butomus umbellatus.
Known protein coding, rRNA, and tRNA genes are shown and color coded as indicated in the lower left corner. Genes shown outside and inside of the circle are transcribed clockwise and counter clockwise, respectively. Repeats longer than 1 kb are shown as colored bars named RR1-RR3. The location of repeat units shown inside or outside of the circle is purely practical; information on directionality is given in Table 4. The inner circle shows GC content. The figure was created using OGDRAW [59].

Sequences of plastid origin in mitochondrial genome of Butomus umbellatus.
Figure 2.
Gene content in selected seed plant mitochondrial genomes.
Dark squares indicate presence of assumed intact, functional genes, lighter gray squares indicate putative pseudogenes, and white squares indicate absence of genes. Numbers below columns are the total numbers of assumed intact, functional genes. The table is modified and expanded from Sloan et al. [2].

Figure 4.
Phylogenetic analysis of substitution rates in three mitochondrial rRNA genes.
Analyses are based on a constraint tree using the topology from analysis of 24 protein coding genes (Fig. 3). Branch lengths are proportional to substitutions per site except the Silene branch in the rrn5 tree having been reduced to ca. 1/3 of its actual length.
