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.

geohabnet: An R package for mapping habitat connectivity for biosecurity and conservation

Methods in Ecology and Evolution, EarlyView.
Abstract Habitat connectivity is critical for the conservation of endangered and endemic species, and conversely, it can hinder efforts to contain the spread of harmful biological agents. Here, we introduce geohabnet: a general, spatially explicit, network‐based R package for evaluating, estimating and mapping landscape connectivity from continuous ...

Environmental factors affect the distribution of two Epichloë fungal endophyte species inhabiting a common host grove bluegrass (Poa alsodes)

Ecology and Evolution, 2019
Aim The endophyte Epichloë alsodes, with known insecticidal properties, is found in a majority of Poa alsodes populations across a latitudinal gradient from North Carolina to New York. A second endophyte, E. schardlii var.

Epichloë (formerly Neotyphodium) fungal endophytes increase adaptation of cool-season perennial grasses to environmental stresses

Acta Agrobotanica, 2019
Many cool-season grass species have evolved with asexual, nonsymptomatic fungal endophytes of the genus Epichloë (formerly Neotyphodium) of the family Clavicipitaceae.

Metabolic potential of endophytic bacteria

Current Opinion in Biotechnology, 2014
The bacterial endophytic microbiome promotes plant growth and health and beneficial effects are in many cases mediated and characterized by metabolic interactions. Recent advances have been made in regard to metabolite production by plant microsymbionts showing that they may produce a range of different types of metabolites.

Engineered Yarrowia lipolytica inducing gene silencing confers control ability against gray mold in plants

Journal of Integrative Plant Biology, EarlyView.
Engineered the plant‐colonizing yeast Yarrowia lipolytica to produce and deliver double‐stranded RNAs targeting key genes of the gray mold fungus Botrytis cinerea produced a ‘living factory’ that continuously synthesizes and releases gene‐silencing molecules on plant surfaces, effectively suppressing the pathogen.
