Differential gene expression in tall fescue tissues in response to water deficit

The Plant Genome, 2022
Tall fescue (Festuca arundinacea Schreb.) is a popular pasture and turf grass particularly known for drought resistance, allowing for its persistence in locations that are unfavorable for other cool‐season grasses.

Tall Fescue and E. coenophiala Genetics Influence Root-Associated Soil Fungi in a Temperate Grassland

Frontiers in Microbiology, 2019
A constitutive, host-specific symbiosis exists between the aboveground fungal endophyte Epichloë coenophiala (Morgan-Jones & W. Gams) and the cool-season grass tall fescue (Lolium arundinaceum (Schreb.) Darbysh.), which is a common forage grass in ...

Metabolomic shifts in beef steers rotationally grazing toxic endophyte-infected tall fescue under fall conditions [PDF]

Frontiers in Veterinary Science
BackgroundFescue toxicosis (FT) results from ingestion of tall fescue infected with the ergot alkaloid (EA)-producing endophyte Epichloë coenophiala. While the vascular system is a major EA target, their biogenic amine-like properties can trigger wider ...

Impact of Low-Level Ergot Alkaloids and Endophyte Presence in Tall Fescue Grass on the Metabolome and Microbiome of Fall-Grazing Steers [PDF]

Toxins
Fescue toxicosis (FT) is a mycotoxin-related disease caused by the ingestion of tall fescue, naturally infected with the ergot alkaloid (EA)-producing endophyte Epichloë coenophiala.

Root Herbivory: Grass Species, Epichloë Endophytes and Moisture Status Make a Difference [PDF]

Microorganisms, 2020
The root-feeding scarab insect Costelytra giveni causes severe damage to pasture ecosystems in New Zealand. Loline alkaloids produced by some Epichloë endophytes deter this insect. In two experiments, tall fescue infected with E.

Risks for animal health related to the presence of ergot alkaloids in feed [PDF]

EFSA Journal, Volume 22, Issue 1, January 2024.
Abstract The European Commission requested EFSA to provide an update of the 2012 Scientific Opinion of the Panel on Contaminants in the Food Chain (CONTAM) on the risks for animal health related to the presence of ergot alkaloids (EAs) in feed. EAs are produced by several fungi of the Claviceps and Epichloë genera.
