We performed a tBLASTn search of the M. esculenta genome and could not find any TpsA family genes containing a chloroplast transit peptides (i.e., potential homologs of casbene and neocembrene synthase) or a CYP726A family gene (data not shown). Understanding how these diterpenoids are produced by the Euphorbiaceae will provide insights into how these plants have evolved to produce a large chemical diversity of these compounds and could lead to methods of improving the supply of specific diterpenoids for trial purposes or therapeutic use.
