Table 1 General features of mitochondrial genomes of two pepper lines and one tobacco line

From: Extensive structural variations between mitochondrial genomes of CMS and normal peppers (Capsicum annuum L.) revealed by complete nucleotide sequencing

Features FS4401 Jeju Nicotiana tabacum
Genome size (bp) 507,452 511,530 430,597
GC content (%) 44.5 44.6 45.0

  1. aAll of the copies of duplicated genes were included.
  2. bComplete sequences of chloroplast genomes of FS4401 [33] and Nicotiana tabacum [34] were used to screen for plastid-derived sequences in mitochondrial genomes of FS4401/Jeju and N. tabacum, respectively, based on the BLASTN algorithm. The value for N. tabacum was different from that of Sugiyama et al. [35] probably due to differences in methodology used to isolate plastid-derived sequence.
  3. cSequences longer than 100 bp and showing similarity higher than 95% between copies were considered repeated. In case repeated sequence units were overlapping, nucleotides that were included in repeated sequences at least one time were counted without repetition.
  4. drpl10, which was reported to be a conserved mitochondrial gene by Kubo and Arimura [32] was added to the list of genes described by Sugiyama et al. in tobacco [35].
  5. eThe number of tRNA genes included in plastid-derived sequences is given in parenthesis.
  6. The tobacco line is ‘Bright Yellow 4′ for which the mitochondrial genome was analyzed by Sugiyama et al. [35].
