Fungal seed treatments of cotton affect boll weevil development

Pest Management Science, Volume 80, Issue 3, Page 1566-1576, March 2024.
Fewer boll weevil larvae hatched and fewer adults emerged from fungal‐treated plants. In addition, the developmental time from oviposition to adult emergence was delayed in the fungal‐treated plants. Abstract BACKGROUND Nonpathogenic fungi associated with plants can enhance plant defenses against stress factors, including herbivory. This study assessed

Acute exposure to ergot alkaloids from endophyte-infected tall fescue does not alter absorptive or barrier function of the isolated bovine ruminal epithelium*

Animal, 2014
Ergot alkaloids in endophyte-infected (Neotyphodium coenophialum) tall fescue (Lolium arundinaceum) have been shown to cause a reduction in blood flow to the rumen epithelium as well as a decrease in volatile fatty acids (VFA) absorption from the washed ...

Risks for animal health related to the presence of ergot alkaloids in feed

EFSA Journal, Volume 22, Issue 1, January 2024.
Abstract The European Commission requested EFSA to provide an update of the 2012 Scientific Opinion of the Panel on Contaminants in the Food Chain (CONTAM) on the risks for animal health related to the presence of ergot alkaloids (EAs) in feed. EAs are produced by several fungi of the Claviceps and Epichloë genera.

Infected–not infected: Factors influencing the abundance of the endophyte Neotyphodium lolii in managed grasslands

, 2013
Temperate grasses are infected with endophytic fungi of the genus Neotyphodium. These fungi asymptomatically live inside the plant’s tissue enhancing resistance of their hosts to herbivores and abiotic stresses.

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.

Micofilas, endófitos fúngicos y alcaloides en poblaciones de Melica stuckertii (Poaceae) del Centro de Argentina Mycophyllas, fungal endophytes and alkaloids in populations of Melica stuckertii (Poaceae) from central Argentina

Boletín de la Sociedad Argentina de Botánica, 2008
Los vástagos de Poaceae pueden establecer con Ascomycetes (Balansieae) asociaciones simbióticas endofíticas denominadas micofilas. Las gramíneas no pueden sintetizar alcaloides en ausencia del endófito fúngico. Melica stuckertii Hack.
