Plastome variations in Convolvulaceae. a IR boundary changes. Calystegia and Convolvulus and other Ipomoea spp. were not shown since they are similar to I. quamoclit in structure. The purple and pink segments located in Dinetus and Dichondra indicate foreign insertions. b Plastomes (last IR removed) of Dichondra and Dinetus have experienced inversions. The pink and purple arrows showed the position of the foreign insertions, which had no homologs with other plastomes. The red ribbon exhibited the position of (c). c Dispersed repeats in Dichondra may create another copy of rpl16. The first exon was duplicated twice. Therefore, the second copy of rpl16 may have two potential combinations (labeled with numbers 1 and 2)
