Extended Data Figure 3. Venn diagram showing unique and shared gene families among members of Orchidaceae, dicots, and Poaceae, and M. acuminata and P. dactylifera.

Numbers represent the number of gene families. Comparison of the 4 groups revealed 474 gene families unique to Orchidaceae and which exist in all 3 Orchidaceae species. If we consider lineage-specific gene families for each group (that is, gene families present in one or a few but not all species in a group), then there are 4,958 unique gene families for Orchidaceae, 7,503 for Poales, 4,494 for the dicots, and 1,560 for the group of M. acuminata and P. dactylifera.
