NOTUNG: reconciled gene tree. A reconciled gene tree with duplication events as obtained from Notung is depicted. Duplication nodes are marked with circles. The branch shading corresponds to the pattern of gymnosperms branching. The blue branch indicates gymnosperm sequences that clustered with angiosperm PAL genes. The green branch indicates a unique gymnosperm branch, while the brown branch indicates gymnosperm sequences clustering with sequences from basal taxa.
