Ginger and turmeric PKSs that are not bona fide chalcone synthases cluster into two major groups, WtPKS1-like (DKS-like) and WtPKS2-like (CURS-like), in a neighbor-joining similarity tree (parsimony and maximum likelihood approaches produce similar trees). Abbreviations are as follows: WtPKS, Wachendorfia thyrsiflora (Haemodoraceae)

In many cases, branches of the tree represent a large number of related sequences, for example, the branch called “Marchantia paleacea PKSs” consisted of four closely related sequences, whereas the branch called “Large Cluster of Rice PKSs” represented over 20 sequences, and the branch called “Other Chalcone Synthases” represented over 100 sequences.
