Comparative analysis of SSRs and INEs in the nine Primulina chloroplast genomes. (A) Number of SSRs of six types; (B) Number of SSRs in different repeat units; (C) Number of SSRs in different regions; (D) Percentage of the length of SSRs in different regions; (E) Number of INEs of four types; (F) Length of four types of INEs, from left to right: forward repeats, palindromic repeats, reverse repeats, and complement repeats.
