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.

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.

Comparison of ergovaline determinations between laboratories in the United States and Japan
NZGA: Research and Practice Series, 2007 Quality assurance and quality control is the foundation of any diagnostic test. The two laboratories in the United States that use HPLC to quantitate endophyte toxins in tall fescue (Festuca arundinacea) and perennial ryegrass (Lolium perenne) are Oregon State University (OSU) and University of Missouri (MU).

Acta Scientiarum Polonorum: Hortorum Cultus, 2013 Neotyphodium and Epichloë endophytes often influence beneficially on the host plant. Thus, could be used as a biological factor enhancing grass growth and resistance to stress factors.

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.

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.

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.

Occurrence of ergovaline in endophyte infected grasses from mediterranean grasslands
, 2000 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.
