Each family was associated with a representative gene and, when possible, with a specific SDR nomenclature initiative HMM. Information on the occurrence of SDRs in different genomes are reported by the taxon name (ViridP: Viridiplantae; LandP: Embryophytae; TracheoP: Tracheophytae; FlowerP: Magnioliophyta). Average pairwise identities were calculated from the sequences of plant genomes. Ambiguously predicted SDRs and families absent in flowering plants were omitted. *: occurrence in Viriplantae was deduced from the presence of homologues in other Green Algae genomes.
