Convergent evolution of caffeine in plants by co-option of exapted ancestral enzymes
R Huang, AJ O'Donnell, JJ Barboline… - Proceedings of the …, 2016 - National Acad Sciences
Convergent evolution is a process that has occurred throughout the tree of life, but the
historical genetic and biochemical context promoting the repeated independent origins of a
trait is rarely understood. The well-known stimulant caffeine, and its xanthine alkaloid
precursors, has evolved multiple times in flowering plant history for various roles in plant
defense and pollination. We have shown that convergent caffeine production, surprisingly,
has evolved by two previously unknown biochemical pathways in chocolate, citrus, and …
