Metabolite levels in shoots after growing in RTM with NAA or BAP when inoculated either as rooted shoots or shoots that had their roots excised prior to inoculation. a individual metabolites in shoots with roots intact with NAA or BAP, b individual metabolites in shoots with roots excised grown in medium containing NAA or BAP, c comparison of total end products (AN + deoxyAN + AB) versus total precursors (AA + DHAA) versus sum of all five metabolites in shoots where inoculum was rooted shoots, d comparison of total end products (AN + deoxyAN + AB) versus total precursors (AA + DHAA) versus sum of all five metabolites in shoots where inoculum was shoots with roots excised. *p ≤ 0.05 when compared to RTM, n ≥ 6. Black RTM, white RTM + 2.5 μM BAP, hatched RTM + 0.25 μM NAA. AN artemisinin, deoxyAN deoxyartemisinin, AB arteannuin B, AA artemisinic acid, DHAA dihydroartemisinic acid, AX all artemisinic metabolites
