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

Tatsiana Shymanovich, Stanley H. Faeth

Abstract 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. pennsylvanica , with known insect‐deterring effects, …

Anti‐insect defenses of A chnatherum robustum (sleepygrass) provided by two Epichloë endophyte species

Tatsiana Shymanovich, Stanley H. Faeth

Abstract Many pooid grasses (Poaceae) harbor Epichloë species (Hypocreales), endophytic fungi that often produce toxic alkaloids which may provide anti‐insect protection for their hosts. Two natural populations of Achnatherum robustum (Vasey) (sleepygrass), in the Lincoln National Forest, Cloudcroft, and Weed (NM, USA), …

Interspecific and intraspecific hybrid Epichloë species symbiotic with the North American native grass Poa alsodes

Tatsiana Shymanovich, Nikki D. Charlton, Ashleigh M. Musso, Jonathan R. Scheerer et autres

The endophyte presence and diversity in natural populations of Poa alsodes were evaluated along a latitudinal transect from the southern distribution range in North Carolina to New York. Two distinct Epichloë hybrid taxa were identified from 23 populations. Each taxon could easily …

Does hybridization of endophytic symbionts in a native grass increase fitness in resource‐limited environments?

Stanley H. Faeth, Martina Oberhofer, Susanna Saari, Kristin E. Haskins et autres

Hybridization is common among plants, animals and microbes. However, the ecological consequences of hybridization for microbes are far less understood than for plants and animals. For symbiotic Epichloë fungi, hybridization is widespread and may augment the well-known benefits of the endophytes to …

Secondary Metabolites from Fungal Endophytes of Echinacea purpurea Suppress Cytokine Secretion by Macrophage-Type Cells

Amninder Kaur, Martina Oberhofer, Monika Juzumaite, Huzefa A. Raja et autres

Botanical extracts of Echinacea purpurea have been widely used for the treatment of upper respiratory infections. We sought to chemically examine fungal endophytes inhabiting E. purpurea, and to identify compounds produced by these endophytes with in vitro cytokine-suppressive activity. Twelve isolates from …

Performance of Endophyte Infected Tall Fescue in Europe and North America

Kari Saikkonen, Timothy D. Phillips, Stanley H. Faeth, Rebecca L. McCulley et autres

Human assisted plant invasions from Europe to North America have been more common than the reverse. We tested endophyte-mediated performance of tall fescue in parallel three year experiments in Europe and the USA using endophyte infected and uninfected wild and cultivated plants. …

Alkaloid Quantities in Endophyte-Infected Tall Fescue are Affected by the Plant-Fungus Combination and Environment

Marjo Helander, Timothy D. Phillips, Stanley H. Faeth, Lowell P. Bush et autres

Many grass species are symbiotic with systemic, vertically-transmitted, asymptomatic Epichloë endophytic fungi. These fungi often produce alkaloids that defend the host against herbivores. We studied how environmental variables affect alkaloids in endophyte-infected tall fescue (Schedonorus phoenix) from three Northern European wild origins …
