Elevated atmospheric CO2 suppresses silicon accumulation and exacerbates endophyte reductions in plant phosphorus

open access: yesFunctional Ecology, Volume 37, Issue 6, Page 1567-1579, June 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many temperate grasses are both hyper‐accumulators of silicon (Si) and hosts of Epichloë fungal endophytes, functional traits which may alleviate environmental stresses such as herbivore attack.

The Known Antimammalian and Insecticidal Alkaloids Are Not Responsible for the Antifungal Activity of Epichloë Endophytes

open access: yesPlants, 2021
Asexual Epichloë sp. endophytes in association with pasture grasses produce agronomically important alkaloids (e.g., lolitrem B, epoxy-janthitrems, ergovaline, peramine, and lolines) that exhibit toxicity to grazing mammals and/or insect pests.

Expression and purification of an adenylation domain from a eukaryotic nonribosomal peptide synthetase: Using structural genomics tools for a challenging target [PDF]

open access: yes, 2010
Nonribosomal peptide synthetases (NRPSs) are large multimodular and multidomain enzymes that are involved in synthesising an array of molecules that are important in human and animal health.

Biological control of plant diseases – What has been achieved and what is the direction?

open access: yesPlant Pathology, Volume 71, Issue 5, Page 1024-1047, June 2022., 2022
Biological control is coming of age and many products are commercially available. This review emphasizes the biology of the three‐way interactions involved and the long route to commercialization. Abstract The global sustainability agenda is increasing the demand for reduction in inputs into agricultural production while maintaining profitable yield of

Ergot alkaloids in New Zealand pastures and their impact

open access: yesNew Zealand Journal of Agricultural Research, Volume 65, Issue 1, Page 1-41, February 2022., 2022
ABSTRACT In identifying endophytes for use in pastures in New Zealand there have been two strategies used, either exclusion of ergopeptine and lolitrem alkaloids or, retaining some ergopeptine expression to enhance the stability of natural defences against invertebrate pests. Both have their strengths and weaknesses.

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

open access: yesAnimal, 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 ...

An integrated targeted and untargeted approach for the analysis of ergot alkaloids in cereals using UHPLC - hybrid quadrupole time-of-flight mass spectrometry [PDF]

open access: yes, 2015
An ultra-high performance liquid chromatography hybrid quadrupole time of flight (Q-TOF) mass spectrometry (MS) method is described for the simultaneous quantitative determination of common ergot alkaloids and the screening, detection and identification ...

Isoflavone Containing Legumes Mitigate Ergot Alkaloid-Induced Vasoconstriction in Goats (Capra hircus)

open access: yesAnimals, 2022
Ergot alkaloids produced by a fungal endophyte that infects tall fescue (Lolium arundinaceum; (E+ TF) can induce constriction of the vasculature in ruminants, resulting in “fescue toxicosis”.

Occurrence of Alkaloids in Grass Seeds Symbiotic With Vertically-Transmitted Epichloë Fungal Endophytes and Its Relationship With Antioxidants

open access: yesFrontiers in Ecology and Evolution, 2018
Host organisms can acquire new functional traits through symbiosis. Seed-transmitted Epichloë fungal endophytes are known to protect host plants against herbivores and increase tolerance to abiotic stresses by alkaloids and antioxidants, respectively ...

Ergovaline poisoning in a herd of dairy cows – a case report [PDF]

open access: yesMedycyna Weterynaryjna, 2019
Endophytes are fungi of the genus Neotyphodium that live in symbiosis with grasses. The effects of this symbiosis can be both negative and positive. The negative effect may be due to alkaloids produced by endophytes that in higher concentrations are toxic to animals. The most common alkaloids produced by Neotyphodium fungi are ergovaline and lolitrem B.
