Tall fescue, Festuca arundinacea, and perennial ryegrass, Lolium perenne. are widely infected with fungal endophytes (Neotyphodium spp.). The symbiosis between plant and fungus leads to synthesis of alkaloids that have been shown to be either toxic or act as feeding deterrents against insect pests.

The mutualistic symbiosis following infection of tall fescue, Festuca arundinacea, and perennial ryegrass, Lolium perenne, by fungal endophyte (Neotyphodium spp.) results in the production of alkaloids that are feeding deterrents or toxic to insects and livestock. If the levels of the alkaloids can

Tall fescue (Festuca arundinacea) forms a symbiotic relationship with the clavicipitalean fungal endophyte Neotyphodium coenophialum. Endophyte-infected grass is tolerant to nematode, but the factors responsible are unknown. One objective of this work was to determine if root extracts of tall fescue

The objective of these experiments was to test the hypothesis that the major alkaloid classes found in endophyte-infected tall fescue could act as growth promoters for vascular smooth muscle. Bovine vascular smooth muscle cells (VSMC) from the dorsal metatarsal artery were grown in vitro and exposed
