, 2007 Festuca arundinacea and Lolium perenne hay and silage samples were collected from 4 dairies in Willamette Valley, Oregon, USA, during July 2003-April 2005 and analysed for their ergovaline content using HPLC and mass spectrometry.

Plant, Cell &Environment, Volume 47, Issue 8, Page 2865-2878, August 2024.Abstract A trade‐off between growth and defence against biotic stresses is common in plants. Fungal endophytes of the genus Epichloë may relieve this trade‐off in their host grasses since they can simultaneously induce plant growth and produce antiherbivore alkaloids that circumvent the need for host defence. The Epichloë ability to decouple the growth‐

Physiological Reports, Volume 12, Issue 13, July 2024.Abstract To better understand mechanisms of serotonin‐ (5‐HT) mediated vasorelaxation, isolated lateral saphenous veins from cattle were assessed for vasoactivity using myography in response to increasing concentrations of 5‐HT or selective 5‐HT receptor agonists.

Acta Scientiarum Polonorum: Hortorum Cultus, 2011 Grasses are very often infected by endophytic fungi of the Neotyphodium and Epichloë genera. They can produce metabolites toxic to livestock as well as beneficially affect grasses. Thus, endophytes can be used for plants improvement.

Stability and purity of selected ryegrass Epichloë endophytes in New Zealand dairy pastures
Grassland Research, Volume 3, Issue 2, Page 113-122, June 2024.Ryegrass tiller sampling is performed to determine Epichloë fungal endophyte infection and strain of Epichloë, to ensure that sown selected endophytes are delivering pasture production, animal health, and productivity benefits for New Zealand dairy farmers.

Vasoconstrictive Responses by the Carotid and Auricular Arteries in goats to Ergot Alkaloid Exposure
Frontiers in Chemistry, 2014 A fungal endophyte (Neotyphodium coenophialum) infects most plants of ‘Kentucky 31’ tall fescue (Lolium arundinaceum) and produces ergot alkaloids that cause persistent constriction of the vascular system in grazing livestock.

Occurrence of ergovaline in endophyte infected grasses from mediterranean grasslands
, 2022 Fungal endophytes of the genera Neo~yphodium and Epich/oc systemicaIly infect several grasses. One of the most relevant aspects of the grass-endophyte interaction is the production of secondary compounds (alkaloids) which are toxic to both vertebrate and invertebrate herbivores.

Frontiers in Chemistry, 2014 The objectives of these experiments were to characterize rumen motility patterns of cattle fed once daily using a real-time wireless telemetry system, determine when to measure rumen motility with this system, and determine the effect of ruminal dosing ...

Recurrent selection in perennial ryegrass (Lolium perenne L.) for reduced levels of ergovaline with particular emphasis on the effect of other ergot alkaloid concentrations [PDF]
, 2015 Perennial ryegass (Lolium perenne L.) has coevolved with symbiotic Epichloë fungal endophytes (Neotyphodium lolii) to form a mutualistic association. Infection with endophyte imparts unique bioactive properties which increase the host plants tolerance to

Frontiers in Nutrition, 2015 It was hypothesized that isoflavones may attenuate ergot alkaloid-induced vasoconstriction and possibly alleviate diminished contractility of vasculature after exposure to ergot alkaloids.
