  1. Table showing major clades in the D14/KAI2 family, as defined at the level of major taxonomic groups. Almost all sequences in the family unambiguously group into one of these clades. Within some clades there are major sub-clades where the lineage has been duplicated; these are listed at the right. Our analysis suggests that land plant D14/KAI2 proteins group into two super-clades, eu-KAI2 and DDK, as indicated on the left of the table
