Table 5 Abundance of SDRs in Scenedesmus and other UTC algal cpDNAs

From: The complete chloroplast genome sequence of the chlorophycean green alga Scenedesmus obliquus reveals a compact gene organization and a biased distribution of genes on the two DNA strands

cpDNA   Number of repeatsa Non-overlapping repeats ≥ 30 bpb
  Maximal size of repeats (bp) ≥ 30 bp ≥ 45 bp Total size (bp) Fraction of genome (%) Fraction of intergenic regions (%)

  1. aRepeats with identical sequences on the same DNA strand or different DNA strands were identified using REPuter.
  2. bThe repeats identified with REPuter were annotated and masked on the genome sequence using RepeatMasker.
