Mean expression levels within the Terpenoid Backbone, Diterpenoid and Zeatin Biosynthesis pathways. A) Normalized mean expression levels for enzymes within the Terpenoid Backbone Biosynthesis (TBB) pathways, namely, plastidic 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway, Diterpenoid Biosynthesis (DB) pathway and Zeatin Biosynthesis (ZB) pathway are provided. B) Normalized mean expression levels for enzymes within the TBB pathways, namely, cytosolic mevalonic acid (MVA) pathway, DB and ZB pathways. Number of E. fischeriana transcripts, from distinct gene clusters, matching each enzyme are shown between brackets in panels A and B.
