Figure 4. Analyses of simple sequence repeats (SSRs) in C. boreale chloroplast genomes.
(A) The frequency of SSRs per sequence type. (B) The frequency of SSRs in intergenic spacer (IGS), coding sequence (CDS), intron and IGS/CDS. IGS/CDS represents SSRs shared in IGS and CDS. (C) The frequency of SSRs in large single copy (LSC), inverted repeat (IR) and small single copy (SSC) regions.
