Figure 3.

Comparison of inverted repeat-single copy boundaries in six representative angiosperms. Variation occurs at each of the four junctions. In Calycanthus rpl2 is not in the IR. JSB occurs within ycf1 in all of the genomes but the amount of the 5' end of ycf1 that is duplicated ranges from 156 bp in Nymphaea to 1583 bp in Amborella. Eleven bp of ndhF is duplicated in Nuphar but none of the other genomes shown have any duplication of the gene. JLA varies from including 5 bp of spacer downstream of trnH in Nicotiana to the inclusion of trnH and an additional 140 bp upstream sequence in the IR in Nuphar.
