Two ubiquitous aldo-keto reductases in the genus Papaver support a patchwork model for morphine pathway evolution [PDF]

Communications Biology
The evolution of morphinan alkaloid biosynthesis in plants of the genus Papaver includes permutation of several processes including gene duplication, fusion, neofunctionalization, and deletion resulting in the present chemotaxonomy.
