Structure of IRb/SSC and SSC/IRa in Amborella and in angiosperms with expanded IR. In Amborella IR/SSC junction occurs within ycf1; truncated copy of ycf1 is thus generated at the IRb/SSC border. Such organisation of IR/SSC junction is characteristic for most angiosperms. Lemna, Ipomoea, Jasminum and Fagopyrum represent different ways of the IR expansion. Jasminum and Fagopyrum both have included ycf1 in the IR. In Lemna not only ycf1, but also rps15 and a part of ndhH belong to the IR, and in Ipomoea overall ndhH and a part of ndhA are also duplicated.
