Mycorrhizal fungi compromise production of endophytic alkaloids, increasing plant susceptibility to an aphid herbivore

open access: yesJournal of Ecology, Volume 113, Issue 6, Page 1368-1381, June 2025.
These findings indicate that symbiotic fungal partnerships and silicon provision may benefit plants but could weaken anti‐herbivore defences when combined. Revealing the complex interactions among diverse fungal symbionts and showcasing their effects on different anti‐herbivore defences (chemical and physical) and herbivore performance for the first ...

Ergot Alkaloids at Doses Close to EU Regulatory Limits Induce Alterations of the Liver and Intestine

open access: yesToxins, 2018
An increase in the occurrence of ergot alkaloids (EAs) contamination has been observed in North America and Europe in recent years. These toxins are well known for their effects on the circulatory and nervous systems.

A Major Facilitator Superfamily Transporter Contributes to Ergot Alkaloid Accumulation but Not Secretion in Aspergillus leporis

open access: yesApplied Microbiology
Ergot alkaloids are fungal natural products with important roles in agriculture and medicine. We used heterologous expression and gene knockout approaches to investigate potential roles for the product of a major facilitator superfamily transporter gene (

Report on the 2017 Proficiency Test of the European Union Reference Laboratory for Mycotoxins: determination of ergot alkaloids in rye [PDF]

open access: yes, 2017
Throughout history, there have been several deadly episodes of food poisoning by ergot alkaloids (EAs) (known as St. Anthony’s fire or ergotism). EAs are secondary metabolites produced by fungi of the Claviceps genus (chiefly Claviceps purpurea), which ...

Psychedelic Drugs in Mental Disorders: Current Clinical Scope and Deep Learning‐Based Advanced Perspectives

open access: yesAdvanced Science, Volume 12, Issue 15, April 17, 2025.
Graphic illustration showing the strategic approaches based on the currently investigated evidence of psychedelics that suggests the challenges and how to address the prescription of mental disorders. These applicable avenues may provide substantial insight into distinguishing between brain networks and psychedelics.

Physiological responses to known intake of ergot alkaloids by steers at environmental temperatures within or greater than their thermoneutral zone

open access: yesFrontiers in Chemistry, 2014
Two studies separated effects of dietary ergot alkaloids from effects of feed intake or ambient temperature on respiration rate (RR), heart rate (HR), surface temperature (ST), rectal temperature (RT), blood pressure (BP), serum hormone, and plasma ...

Effects of Toxic Fescue Exposure on Vaginal Microbial Communities of Crossbred Beef Cows [PDF]

open access: yes, 2018
The consumption of toxic fescue by beef cattle results in several adverse physiological effects such as reduced reproductive success, severe vasoconstriction resulting in hoof sloughing, low body condition scores, hyperthermia, decreased prolactin levels,

Omic characterisation of multi‐component defences against the necrotrophic pathogen Pyrenophora tritici‐repentis in wheat

open access: yesPlant Biology, Volume 27, Issue 3, Page 347-361, April 2025.
Resistance against Tan spot (caused by Pyrenophora tritici‐repentis) in wheat can involve cell wall defences or an absence of susceptibility factors. Abstract Tan Spot disease is caused by the necrotrophic pathogen Pyrenophora tritici‐repentis (Ptr) and poses a significant threat to global wheat production.

Comparative study of the biological activities of the aqueous extracts of two spontaneous plants harvested in the Algerian Sahara [PDF]

open access: yesarXiv, 2020
The present study investigates the insecticidal and herbicidal effects of leaf extracts from two plants were harvested in the Northern Algerian Sahara. These are Cleome arabica (Capparaceae) and Pergularia tomentosa (Asclepiadaceae). The efficacy of the extracts from the plants was evaluated by the reflux extraction method.

Prophylactic use of ergot alkaloids in the third stage of labour.

open access: yesCochrane Database of Systematic Reviews, 2018
BACKGROUND Previous research has shown that the prophylactic use of uterotonic agents in the third stage of labour reduces postpartum blood loss and moderate to severe postpartum haemorrhage (PPH).
