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.

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]
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?
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
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.

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]
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 ...

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”.

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]
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.
