The position of Amborella in the angiosperm phylogenetic tree. Taxa for which whole-genome sequences have been published are indicated in parentheses. The node highlighted by a star on the tree identifies the 'ancestral angiosperm', or most recent common ancestor of all living angiosperms. An Amborella genome sequence will allow the ancestral genes and genomic features of living angiosperms to be identified and will provide the essential root for angiosperm comparative genomics. Based on [14,15].
