The present invention provides a method of producing lysergic acid and other ergot alkaloids by genetic modification of a fungus. A strain of fungus comprising Aspergillus fumigatus (A. fumigatus) or any fungus having a pathway similar to Aspergillus fumigatus and expressing one or more genes of the ergot alkaloid biosynthesis pathway from one or more fungus selected from the group consisting of Epichloë festucae var. lolii×Epichloë typhina isolate Lp1 (E. sp. Lp1); Claviceps species; Claviceps africana (C. africana); Claviceps gigantea (C. gigantea); Epichloë coenophiala and Periglandula species, wherein gene easA or gene easM is inactivated in said A. fumigatus or said fungus having a pathway similar to Aspergillus fumigatus, is provided.
本发明提供了一种通过遗传修饰真菌生产麦角酸和其他麦角生物碱的方法。一株真菌包括烟曲霉(A. fumigatus)或任何具有与烟曲霉相似途径的真菌,并表达麦角生物碱生物合成途径的一个或多个基因,该基因来自选自Epichloë festucae var.lolii×Epichloë typhina isolate Lp1 (E. sp. Lp1);Claviceps species;Claviceps africana (C.africana);Claviceps gigantea (C.gigantea);Epichloë coenophiala 和 Periglandula species,其中基因 easA 或基因 easM 在所述烟曲霉或所述具有与烟曲霉相似途径的真菌中失活。
