A Simple Thin-Layer Chromatographic Method for the Detection of Ergovaline in Leaf Sheaths of Tall Fescue (Festuca Arundinacea) Infected with Neotyphodium Coenophialum

, 2001
A relatively simple and inexpensive thin-layer chromatographic (TLC) method is described for the detection and semiquantitative measurement of ergovaline in leaf sheaths of tall fescue ( Festuca arundinacea).

Determination of the Ergot Alkaloid Ergovaline in Tall Fescue Seed and Straw Using a QuEChERS Extraction Method with High-Performance Liquid Chromatography–Fluorescence Detection

Ergovaline is an ergot alkaloid produced by the symbiotic endophyte Epichloë coenophiala which can colonize varieties of the cool-season grass tall fescue (Festuca arundinacea).

The Effects of Exposure to Endophyte-Infected Tall Fescue Seed on Faecal and Urine Concentrations of Ergovaline and Lysergic Acid in Mature Gelding Horses [PDF]

, 2023
Despite the good nutritive value of endophyte-infected tall fescue, consumption by livestock results in a decrease in both reproductive and growth performance due to ergot alkaloids produced by an endophytic fungus (Cross et al., 1995).

Correlation of endophyte toxins (ergovaline and lolitrem B) with clinical disease : fescue foot and perennial ryegrass staggers [PDF]

Endophytic fungi (A. coenophialum and A. lolii) which infect grasses produce ergot alkaloids that serve as the grasses' chemical defenses and enhance the vigor of the grass. Turf-type tall fescue with high endophyte levels has been deliberately developed

Ergovaline concentrations in simulated herbivory experiment

, 2014
Data are from an experiment simulating herbivory and saliva application on 32 Festuca rubra plants infected with Epichloë festucae. We used two simulated herbivory treatments consisting of fortnightly and monthly clipping and a control of no herbivory.

Elevated ergovaline levels detected in ΔsidN infected plants.

, 2013
HPLC analysis of ergovaline production was carried out on perennial ryegrass pseudostems infected with wild-type E. festucae Fl1 (WT), ΔsidN mutant 85 (ΔsidN), and complemented ΔsidN strains (C-sidN 1 and C-sidN 2).
