Temporal host–symbiont dynamics in community contexts: Impacts of host fitness and vertical transmission efficiency on symbiosis prevalence

Functional Ecology, Volume 38, Issue 12, Page 2610-2622, December 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Symbiotic associations play a role in plant ecology and evolution, but the outcome of the interaction depends on the life‐history traits of the partners and the environmental context.

Fungal endophytes can modulate plant invasion

Biological Reviews, Volume 99, Issue 5, Page 1652-1671, October 2024.
ABSTRACT Symbiotic organisms may contribute to a host plant's success or failure to grow, its ability to maintain viable populations, and potentially, its probability of establishment and spread outside its native range. Intercellular and intracellular microbial symbionts that are asymptomatic in their plant host during some or all of their life cycle –

General Access to Clavine Alkaloids via a Rhodium(I)‐Catalyzed Diastereoselective Hayashi‐Miyaura Reaction

Advanced Synthesis &Catalysis, Volume 366, Issue 6, Page 1397-1404, March 19, 2024.
Abstract We report the development of the diastereoselective rhodium(I)‐catalyzed intramolecular conjugate addition (Hayashi‐Miyaura reaction) of robust and easily handled 4‐pinacolboronic ester D‐tryptophan derivatives tethering an activated alkene as the acceptor.

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

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.

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 ...

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.

Mitigation of ergot vasoconstriction by clover isoflavones in goats (Capra hircus)

Frontiers in Veterinary Science, 2016
Ergot alkaloids produced by a fungal endophyte (Epichloë coenophiala; formerly Neotyphodium coenphialum) that infects tall fescue (Lolium arundinaceum) can induce persistent constriction of the vasculature in ruminants, hindering their capability to ...

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.
