Tolerancia a la salinidad de festuca alta, naturalizada y comercial, libre e infectada con endófitos durante la germinación

Revista de la Facultad de Agronomía, 2022
Se realizó un experimento en una cámara de germinación con el objetivo de comparar la tolerancia a la salinidad de distintos materiales de festuca alta (Schedonorus arundinaceus) libres e infectados con el endófito Epichloë coenophiala durante la ...

Silicon and Epichloë‐endophyte defences in a model temperate grass diminish feeding efficiency and immunity of an insect folivore

Functional Ecology, Volume 37, Issue 12, Page 3177-3192, December 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants deploy diverse anti‐herbivore defences which reduce feeding and performance of herbivores. Temperate grasses use silicon (Si) accumulation and Epichloë‐endophytes for physical and chemical (i.e. endophytic‐alkaloids) defence against insect herbivores.

Epichloë endophytes alter inducible indirect defences in host grasses. [PDF]

PLoS ONE, 2014
Epichloë endophytes are common symbionts living asymptomatically in pooid grasses and may provide chemical defences against herbivorous insects. While the mechanisms underlying these fungal defences have been well studied, it remains unknown whether ...

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

Functional 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.

Increased abundance and productivity of a grassland bird after experimental control of invasive tall fescue

Restoration Ecology, Volume 30, Issue 8, November 2022., 2022
Tall fescue (Schedonorus arundinaceus) is a widespread invasive grass in the United States that degrades habitat quality for biodiversity. Herbicide followed by seeding of native plants reduces tall fescue and is predicted to restore habitat quality over time, but little is known about short‐term (1–2 year) impacts on native species.

Ergot alkaloids in New Zealand pastures and their impact

New 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.

Influence of Tall Fescue Epichloë Endophytes on Rhizosphere Soil Microbiome

Microorganisms, 2021
Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) often forms a symbiotic relationship with fungal endophytes (Epichloë coenophiala), which provides increased plant performance and greater tolerance to environmental stress compared to endophyte-

Behavioral and Physiological Alterations in Angus Steers Grazing Endophyte-Infected Toxic Fescue during Late Fall

Toxins, 2023
Fescue toxicosis is caused by grazing ergot alkaloid-producing endophyte (Epichloë coenophiala)-infected tall fescue (E+). Summer grazing of E+ leads to decreased productivity, associated impaired thermoregulation, and altered behavior.

Data on litter quality of host grass plants with and without fungal endophytes

Data in Brief, 2016
Certain Pooideae species form persistent symbiosis with fungal endophytes of Epichloë genus. Although endophytes are known to impact the ecology and evolution of host species, their effects on parameters related with quality of plant biomass has been ...

Insect oviposition preference between Epichloë‐symbiotic and Epichloë‐free grasses does not necessarily reflect larval performance

Ecology and Evolution, Volume 10, Issue 14, Page 7242-7249, July 2020., 2020
In this study, we addressed the question how insect oviposition preference reflects larval performance in a satyrine butterfly when the host plant harbors a fungal endophyte. Against predictions, we found no clear association between oviposition preference and larval performance.
