Ergot Alkaloids Produced by Endophytic Fungi of the Genus Epichloë

Toxins, 2015
The development of fungal endophytes of the genus Epichloë in grasses results in the production of different groups of alkaloids, whose mechanism and biological spectrum of toxicity can differ considerably.

Epichloë Endophyte Infection Rates and Alkaloid Content in Commercially Available Grass Seed Mixtures in Europe

Microorganisms, 2020
Fungal endophytes of the genus Epichloë live symbiotically in cool season grass species and can produce alkaloids toxic to insects and vertebrates, yet reports of intoxication of grazing animals have been rare in Europe in contrast to overseas.

Perennial Ryegrass Alkaloids Increase Respiration Rate and Decrease Plasma Prolactin in Merino Sheep under Both Thermoneutral and Mild Heat Conditions

Toxins, 2019
A study was undertaken to determine the effects of feeding two levels of perennial ryegrass alkaloids (nil vs. moderate) under two climatic conditions. Alkaloids were fed via endophyte-infected perennial ryegrass seed and hay.

Bovine neuronal vesicular glutamate transporter activity is inhibited by ergovaline and other ergopeptines [PDF]

Journal of Dairy Science, 2011
l-Glutamate (Glu) is a major excitatory neurotransmitter responsible for neurotransmission in the vertebrate central nervous system. Vesicular Glu transporters VGLUT1 and VGLUT2 concentrate (50mM) Glu [Michaelis constant (measuring affinity), or K(m),=1 to 4mM] into synaptic vesicles (SV) for subsequent release into the synaptic cleft of glutamatergic ...

Exposure to Ergot Alkaloids During Gestation Reduces Fetal Growth in Sheep

Frontiers in Chemistry, 2014
Tall fescue [Lolium arundinaceum (Schreb.) Darbysh; Schedonorus phoenix (Scop.) Holub] is the primary cool season perennial grass in the eastern U.S. Most tall fescue contains an endophyte (Neotyphodium coenophialum), which produces ergot alkaloids that ...

Effects of red clover isoflavones on tall fescue seed fermentation and microbial populations in vitro. [PDF]

PLoS ONE, 2018
Negative impacts of endophyte-infected Lolium arundinaceum (Darbyshire) (tall fescue) are responsible for over $2 billion in losses to livestock producers annually.

Fungal alkaloid occurrence during seedling establishment and early growth in Lolium perenne seedlings infected with Epichloë festucae var. lolii and the influence of adult Argentine stem weevil (Listronotus bonariensis) feeding on alkaloid concentrations : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science (MSc) in Agriculture Science at Massey University, Palmerston North, New Zealand [PDF]

, 2016
Fungal endophytes of the genus Epichloë often form stable, symbiotic, and mutualistic relationships with grasses of the Pooideae, including perennial ryegrass (Lolium perenne L.).
