Ergovaline in populations of endophyte infected Festuca rubra subsp. pruinosa
, 2006 Festuca rubra subsp. pruinosa is a grass whose preferred habitat are coastal cliffs, a harsh environment where plants grow in cavities and are exposed to salt water spray. This grass species is systemically infected by the fungal endophyte Epichloë festucae and the interaction is asymptomatic.

Grassland Research, Volume 4, Issue 4, Page 332-340, December 2025.The growth performance and physiology variations of perennial ryegrass with (E+) and without endophyte (E−) were evaluated after they were subjected to ZnCl2 and CdCl2 treatments. Abstract Background The endophyte Epichloë festucae var. lolii forms mutualistic symbiosis with perennial ryegrass, and their relationship under heavy metal stress needs to ...

Evaluating pasture forage plant breeding achievements: a review
New Zealand Journal of Agricultural Research, Volume 68, Issue 6, Page 1146-1220, December 2025.ABSTRACT Forage plant breeding aims to deliver cultivars that increase on‐farm productivity through improved seasonal and annual yield, persistence of yield in perennials, and nutritive and feeding value. Breeding is generally undertaken in highly controlled field trials with individual plants or rows.

Variation in the expression of ergot alkaloids between individual tillers of perennial ryegrass
Frontiers in Chemistry, 2014 Epichloë fungal endophytes of cool season grasses are well known to produce a range of alkaloids of benefit to the host. Some of these compounds are advantageous to agriculture due to qualities that promote pasture persistence (e.g.

A comparison of four methods for determining pasture botanical composition
Grassland Research, Volume 4, Issue 3, Page 260-268, September 2025.The objective of this study was to determine an accurate and efficient method for researchers and/or practitioners to monitor botanical composition. The evaluation methods included visual estimation (top left), occupancy grid (top right), point quadrat (bottom left), and step point (bottom right).

Grass and Forage Science, Volume 80, Issue 2, April-June 2025.ABSTRACT Ruminant livestock production is the greatest source of agricultural greenhouse gas (GHG) production, largely due to enteric methane (CH4) emissions. While the optimised feed rations used in confinement dairy and beef finishing operations can reduce CH4 emissions of individual animals compared with cattle on forage diets, the profitability of ...
