  1. a: contains corrections to distance due to scaffold fusions. b: Populus comparisons include rearrangements during the re-diploidization of the ancestral tetraploid. c: some missing homologs in the Ricinus comparisons are simply not sequenced, while in the other comparisons, missing homologs are virtually all absent from the genome.
