N (nine NADH dehydrogenase genes, five ATPThe Mitochondrial Genome of ButomusFigure 1. Circular map of the mitochondrial genome of Butomus umbellatus. Known protein coding, rRNA, and tRNA genes are shown and color coded as indicated inside the reduced 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 your circle is purely practical; facts on directionality is offered in Table 4. The inner circle shows GC content material. The figure was designed utilizing OGDRAW [59]. doi:10.1371/journal.pone.0061552.gsynthase genes, three cytochrome C reductases, one particular cytochrome C reductase) and 4 are involved in cytochrome C biogenesis. Collectively with matR and mttB these 24 genes are almost ubiquitously discovered in all full seed plant mitochondria sequenced so far. Exceptions would be the loss of cox2 in members of Fabaceae [36], of mttB in Vitis [37] and Boea [15], of a functional copy of ccmFc in Silene conica [2], and the potential loss of atp8 in Allium [38]. Two succinate dehydrogenase genes, sdh3 and sdh4, are present within the mitochondrial genome of Cycas, but based on Southern hybridization Adams et al. [39] recommended that these genes had been lost repeatedly among the angiosperms, and in some cases transferred to the nucleus [38]. Amongst the Alismatales, data from Adams et al. [39] indicated presence of each genes in 3 generaof Araceae, and absence in two genera of Hydrocharitaceae and 1 genus of Alismataceae. Hence, the absence of each genes in Butomus is just not surprising, even though we’ve got identified a partial, 157 bp long, pseudogene-like sequence of sdh4. Within the entirely sequenced mitochondrial genome of Spirodela (Araceae) sdh4 is present as recommended by Adams et al.2049109-24-0 site [39], but sdh3 will not be. Only 4 ribosomal protein genes, rps1, rps3, rps7, and rps12, are found in the mitochondrial genome of Butomus. These genes are only seldom lost amongst angiosperms (Fig. two) though Adams et al. [38] did report loss of rps7 in the Hydrocharitaceae and Alismataceae. A lower quantity of ribosomal genes have so far only been recorded for species of Silene [2]. In Spirodela, no much less than 10 functional ribosomal genes have been detected.

Repeated transfer and incorporation into the mitochondrial genome of 16S rRNA is supported by the two occurrences of partial or comprehensive 16S rRNA sequences in Cucumis and Boea, Therefore lending indirect assistance to the hypothesis of gene conversion in Silene.tRNA GenesNone in the angiosperm mitochondrial genomes sequenced to date has incorporated a full set of tRNA genes, and genome of Butomus is no exception. Only 12 various tRNA genes might be found (Table two, Fig. two).
