Enzymes from Fungal and Plant Origin Required for Chemical Diversification of Insecticidal Loline Alkaloids in Grass-Epichloë Symbiota
Figure 8
Summarized loline-alkaloid biosynthetic pathway.
Labeled arrows are for steps that contribute to diversity of the lolines. Presence or absence of functional copies of lolO, lolN, lolM, or lolP, or a plant acetyltransferase activity, determine which alkaloids accumulate in the symbiotic plant as the pathway end-products.
