Fig. 8. Proposed biosynthetic pathways to 3-hydroxy acids, 3-hydroxy FAMEs and 2-alkanols. Full arrows describe the biosynthetic pathways most consistent with our A. arborescens leaf wax analysis results. Broken arrows describe two alternative pathways towards 2-alkanols that are neither supported, nor can be ruled out solely on the basis of our results herein. Intermediates shown in square brackets are expected to be unstable and thus undetectable in surface wax. Enzymes shown in round brackets denote situations where the respective reactions can also proceed non-enzymatically.
