The table shows the size of the IR, how much the IR has expanded compared to L. philippensis, the amount of the expanded repeat sequence that came from the LSC and from the SSC, the number of originally single-copy genes now found in the IR, and the number of genes originally found in the LSC and SSC now contained in the IR. The Aureolaria, Buchnera, and Striga results are from our analysis while the other data were previously published for Lindenbergia philippensis, Schwalbea americana [19], Pedicularis cheilanthifolia [28], Triphysaria versicolor [20]
