Performance of young endophyte-free and endophyte-infected tall fescue (Festuca arundinacea) plants under partial and total submergence

, 2023
Context. Tall fescue (Festuca arundinacea Schreb.) is a valuable temperate forage grass. Tall fescue plants associated with Epichloë fungal endophytes are successfully spreading in grassland regions that are recurrently exposed to flooding. Aims.

Geographic Variation in Festuca rubra L. Ploidy Levels and Systemic Fungal Endophyte Frequencies.

PLoS ONE, 2016
Polyploidy and symbiotic Epichloë fungal endophytes are common and heritable characteristics that can facilitate environmental range expansion in grasses.

Goose herbivory alters soil microbial community functional potential in a sub‐Arctic wetland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory alters below‐ground resource dynamics via direct and indirect mechanisms, yet its effects on microbial functional potential remain poorly understood. This limits our understanding of the mechanisms that link animal, plant and microbial functional roles in ...

Climate change effects on biomass and greenhouse gas emissions are ameliorated by nontoxic endophytes in southeastern USA transition zone tall fescue pastures

Grassland Research
Background The plant–microbe interaction between tall fescue and its endophyte Epichloë coenophiala can affect ecosystem responses to changing rainfall patterns and increasing temperatures.

The Effects of Endophyte-Infected Tall Fescue on the Production and Reproductive Performance Parameters of Beef Cattle and Calves

Grasses
Records from 2012 to 2019 for two herds were analyzed to determine how tall fescue (Schedonorus arundinaceus (Schreb.) Dumont) endophyte (Epichloë coenophialum) status affected the productivity of spring-calving cows and calves. Pastures either contained

Tall fescue cultivar and fungal endophyte combinations influence plant growth and root exudate composition

Frontiers in Plant Science, 2015
Tall fescue (Lolium arundinaceum (Schreb.)) is a cool-season perennial grass used in pastures throughout the Southeastern United States. The grass can harbor a shoot-specific fungal endophyte (Epichloë coenophiala) thought to provide the plant with ...

Maternal Exposure to Ozone Modulates the Endophyte-Conferred Resistance to Aphids in Lolium multiflorum Plants

Insects, 2020
Plants are challenged by biotic and abiotic stress factors and the incidence of one can increase or decrease resistance to another. These relations can also occur transgenerationally.

Amphibian‐Derived Peptide OA‐AL14 Alleviates UVB‐Induced Skin Photoaging via Autophagy Activation Mediated by the AMPK/mTOR Pathway

Integrative Zoology, EarlyView.
The schematic diagram illustrates that the amphibian‐derived peptide OA‐AL14 protects against UVB‐induced skin photoaging through a dual mechanism: activating the Nrf2 pathway to counteract oxidative stress and modulating the AMPK/mTOR axis to induce protective autophagy. ABSTRACT Skin photoaging, primarily driven by ultraviolet B (UVB) radiation, is a

Leaf endophyte load influences fungal garden development in leaf-cutting ants

BMC Ecology, 2012
Background Previous work has shown that leaf-cutting ants prefer to cut leaf material with relatively low fungal endophyte content. This preference suggests that fungal endophytes exact a cost on the ants or on the development of their colonies.

Microbiota‐Mediated Sequential Gallery Colonization by Adults and Larvae of an Invasive Bark Beetle

Integrative Zoology, EarlyView.
Dispersing adult beetles harbor more pinitol‐degrading microbes to colonize novel host pines with high levels of pinitol stress. These microbes from the beetle's exoskeleton and gut will be transmitted into the gallery via adults’ feeding and frass, whose proliferation in the gallery contributes to the formation of a low‐pinitol microhabitat.
