39 gene duplications, identifiers of duplication nodes correspond to those of the consensus tree. Unresolved nodes The tree topology for BAM2/BAM7 is not yet resolved. The expected topology is discussed in section evidence 8. No stable topology and / or significant branch support was achieved for orthologs from Chlamydomonas reinhardtii (CHLRE), Physcomitrella patens subsp. patens (PHYPA), Selaginella moellendorffii (SELMO) and Volvox carteri (VOLCA).
