简介内容:Lolitrem B is one of many toxins produced by a fungus called Epichlo? festucae (var. lolii), which grows in perennial ryegrass. The fungus is symbiotic with the ryegrass; it doesn´t harm the plant, and the toxins it produces kill insects that feed on ryegrass. Lolitrem B is one of these toxins, but it is also harmful to mammals.
