Integrative interactomics applied to bovine fescue toxicosis [PDF]

Scientific Reports, 2022
Bovine fescue toxicosis (FT) is caused by grazing ergot alkaloid-producing endophyte (Epichloë coenophiala)-infected tall fescue. Endophyte’s effects on the animal’s microbiota and metabolism were investigated recently, but its effects in planta or on ...

Evaluation of Resistance to Fescue Toxicosis in Purebred Angus Cattle Utilizing Animal Performance and Cytokine Response [PDF]

Toxins, 2020
Fescue toxicosis is a multifaceted syndrome common in cattle grazing endophyte-infected tall fescue; however, varying symptomatic responses potentially imply genetic tolerance to the syndrome.

Use of Integrative Interactomics for Improvement of Farm Animal Health and Welfare: An Example with Fescue Toxicosis [PDF]

Toxins, 2020
Rapid scientific advances are increasing our understanding of the way complex biological interactions integrate to maintain homeostatic balance and how seemingly small, localized perturbations can lead to systemic effects.

Beef cattle that respond differently to fescue toxicosis have distinct gastrointestinal tract microbiota. [PDF]

PLoS ONE, 2020
Tall fescue (Lolium arundinaceum) is a widely used forage grass which shares a symbiosis with the endophytic fungus Epichloë coenophiala. The endophyte produces an alkaloid toxin that provides herbivory, heat and drought resistance to the grass, but can ...

Condensed Tannins Attributes: Potential Solution to Fescue Toxicosis?

Agriculture, 2023
Tall fescue (Schedonorus arundinaceous (Schreb.) Dumort. nom. cons. Lolium arundinaceum (Schreb.) Darbysh.) toxicosis results from the consumption of alkaloids released by wild-type endophytes (Epichloe coenophiala) that live in symbiosis with the plant.

Endophyte Infected Tall Fescue: Plant Symbiosis to Animal Toxicosis [PDF]

Frontiers in Veterinary Science, 2021
Endophyte-infected fescue is a major cool season forage used for livestock production in the United States and through other areas of the world. A unique aspect of this forage resource is the symbiotic relationship with an endophytic fungus (Epichloë ...

Determining the earliest growth stage to detect the presence of endophytes in tall fescue and perennial ryegrass seedlings using molecular markers

Grassland Research, Volume 2, Issue 2, Page 106-111, June 2023., 2023
Many forage grasses have a beneficial fungus living inside them. The presence of this fungus is a necessity to many producers. Knowing when and how to test for it has been a problem in the past. Here, we compare different methods of fungal testing and different time points that will help producers make testing decisions. Abstract Background Tall fescue

Elevated atmospheric CO2 suppresses silicon accumulation and exacerbates endophyte reductions in plant phosphorus

Functional Ecology, Volume 37, Issue 6, Page 1567-1579, June 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many temperate grasses are both hyper‐accumulators of silicon (Si) and hosts of Epichloë fungal endophytes, functional traits which may alleviate environmental stresses such as herbivore attack.

Clover frost‐seeding rate effects on productivity and nutritive value of tall fescue pastures during the year of establishment

Crop Science, Volume 62, Issue 3, Page 1394-1403, May/June 2022., 2022
Abstract Frost seeding is a low‐cost effective strategy to introduce legumes into existing perennial pastures; however, it has been deemed unreliable in the upper southeast USA. We evaluated frost seeding planting rate effects of clover (Trifolium spp.) during the year of establishment on productivity and nutritive value of clover‐tall fescue [Festuca ...

Ergot alkaloids in New Zealand pastures and their impact

New Zealand Journal of Agricultural Research, Volume 65, Issue 1, Page 1-41, February 2022., 2022
ABSTRACT In identifying endophytes for use in pastures in New Zealand there have been two strategies used, either exclusion of ergopeptine and lolitrem alkaloids or, retaining some ergopeptine expression to enhance the stability of natural defences against invertebrate pests. Both have their strengths and weaknesses.
