Plant terpene specialized metabolism: complex networks or simple linear pathways?

The Plant Journal, Volume 114, Issue 5, Page 1178-1201, June 2023., 2023
SUMMARY From the perspectives of pathway evolution, discovery and engineering of plant specialized metabolism, the nature of the biosynthetic routes represents a critical aspect. Classical models depict biosynthesis typically from an end‐point angle and as linear, for example, connecting central and specialized metabolism. As the number of functionally
