Fungal alkaloids in populations of endophyte-infected Festuca rubra subsp. pruinosa [PDF]

, 2007
Festuca rubra subsp. pruinosa is a grass that grows on coastal cliffs along the Atlantic coast of Europe. Asymptomatic plants of this species are systemically infected by the fungal endophyte Epichloë festucae.

Pre-treatment with ergovaline does not alter tremors induced by lolitrem B

, 2018
Perennial ryegrass (Lolium perenne) infected with the common-toxic (wild-type) endophyte (Epichloë festucae var. lolii) is characterised by the production of lolitrem B which induces ryegrass staggers in grazing animals.

Sheep urinary lysergyls as a biomarker of exposure to ergovaline: A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Science with Honours at Lincoln University

, 2003
Ergovaline is one of the ergot alkaloid toxins produced through association of the endophyte Neotyphodium lolii with perennial ryegrass. Ergovaline affects the health and productivity of sheep grazing ryegrass infected with Neotyphodium lolii. Ergovaline

Intermediate Steps Towards the Total Synthesis of Ergovaline

, 2018
Ergovaline is an ergot alkaloid isolated from tall fescue grasses infested with the fungus Neotyphodium lolii. It poses a significant threat to the health of forage animals (especially cattle and horses in Kentucky) since it can produce a toxicosis in ...

Fluctuations in the concentration of ergovaline and lolitrem B produced by the wild-type endophyte (Neotyphodium lolii) in perennial ryegrass (Lolium perenne) pasture

, 2011
Mammalian toxins produced by the wild-type endophyte, Neotyphodium lolii, in perennial ryegrass (PRG) pasture cause production losses and animal health and welfare problems in livestock.

Genetic manipulation of the ergot alkaloid pathway in Epichloë festucae var. lolii and its effect on black beetle feeding deterrence

, 2021
Epichloë endophytes are filamentous fungi (family Clavicipitaceae) that live in symbiotic associations with grasses in the sub family Poöideae. In New Zealand, E. festucae var.

Comparative study on the metabolism of the ergot alkaloids ergocristine, ergocryptine, ergotamine, and ergovaline in equine and human S9 fractions and equine liver preparations

, 2019
1. Ergopeptine alkaloids like ergovaline and ergotamine are suspected to be associated with fescue toxicosis and ergotism in horses. Information on the metabolism of ergot alkaloids is scarce, especially in horses, but needed for toxicological analysis ...

Preference for tannin-containing supplements by sheep consuming endophyte-infected tall fescue hay

, 2013
Tannins may bind to alkaloids in endophyte-infected (E+) tall fescue and attenuate fescue toxicosis. To test this hypothesis, thirty-two 4-mo-old lambs were randomly assigned to 4 treatments (8 lambs/treatment) in a 2 by 2 factorial design that included ...
