Fig. 5

a–c Phylogenetic trees of germacrene A synthase (GAS), oxidase (GAO), and costunolide synthase (COS). They were constructed by neighbor-joining method, using deduced proteins of Cichorium endivia (Ce) contigs (in bold) and those retrieved from public databases of Lactuca sativa (Lsat or Ls) and Cichorium intybus (Ci) species. Bootstraps values were based on 1000 replicates. The line lengths indicate the relative distances between nodes. Underlined proteins have biochemically assessed functions (references in the text)
