The ergot alkaloid pathway showing steps that result in diversification of compounds. Pathway steps are color-coded based on the position or diversification within the pathway, Blue = early steps to the intermediate chanoclavine, Green = mid steps leading to the tetracyclic clavines, Red = late steps represented by the lysergic acid amides and the complex ergopeptines, Purple = steps to fumigaclavines produced by Trichocomaceae.
