Independent Evolution of a Lysergic Acid Amide in Aspergillus Species.

ABSTRACT: Ergot alkaloids derived from lysergic acid have impacted humanity as contaminants of crops and as the bases of pharmaceuticals prescribed to treat dementia, migraines, and other disorders. Several plant-associated fungi in the Clavicipitaceae produce lysergic acid derivatives, but many of these fungi are difficult to culture and manipulate. Some Aspergillus species, which may be more ideal experimental and industrial organisms, contain an alternate branch of the ergot alkaloid pathway, but none were known to produce lysergic acid derivatives. We mined the genomes of Aspergillus species for ergot alkaloid synthesis (eas) gene clusters and discovered that three species, A. leporis, A. homomorphus, and A. hancockii, had eas clusters indicative of the capacity to produce a lyserg
