Fungal endophytes can modulate plant invasion
ABSTRACT Symbiotic organisms may contribute to a host plant's success or failure to grow, its ability to maintain viable populations, and potentially, its probability of establishment and spread outside its native range. Intercellular and intracellular microbial symbionts that are asymptomatic in their plant host during some or all of their life cycle –

Imperfect Vertical Transmission of the Endophyte Neotyphodium in Exotic Grasses in Grasslands of the Flooding Pampa [PDF]
Cool-season grasses establish symbioses with vertically transmitted Neotyphodium endophytes widespread in nature. The frequency of endophyte-infected plants in closed populations (i.e., without migrations) depends on both the differential fitness between infected and non-infected plants, and the endophyte-transmission efficiency. Most studies have been

Abstract We report the development of the diastereoselective rhodium(I)‐catalyzed intramolecular conjugate addition (Hayashi‐Miyaura reaction) of robust and easily handled 4‐pinacolboronic ester D‐tryptophan derivatives tethering an activated alkene as the acceptor.

Neotyphodium and Epichloë endophytes often influence beneficially on the host plant. Thus, could be used as a biological factor enhancing grass growth and resistance to stress factors.

Ergovaline Stability in Tall Fescue Based on Sample Handling and Storage Methods
Ergovaline is an ergot alkaloid produced by the endophyte Neotyphodium coenophialum (Morgan-Jones and Gams) found in tall fescue (Schedonorus arundinacea (Schreb.) Dumort.) and blamed for a multitude of livestock disorders.

Fungal seed treatments of cotton affect boll weevil development
Fewer boll weevil larvae hatched and fewer adults emerged from fungal‐treated plants. In addition, the developmental time from oviposition to adult emergence was delayed in the fungal‐treated plants. Abstract BACKGROUND Nonpathogenic fungi associated with plants can enhance plant defenses against stress factors, including herbivory. This study assessed

Risks for animal health related to the presence of ergot alkaloids in feed
Abstract The European Commission requested EFSA to provide an update of the 2012 Scientific Opinion of the Panel on Contaminants in the Food Chain (CONTAM) on the risks for animal health related to the presence of ergot alkaloids (EAs) in feed. EAs are produced by several fungi of the Claviceps and Epichloë genera.

Grasses are very often infected by endophytic fungi of the Neotyphodium and Epichloë genera. They can produce metabolites toxic to livestock as well as beneficially affect grasses. Thus, endophytes can be used for plants improvement.

Distribution of Neotyphodium endophytes in naturalised ryegrasses (Lolium spp.) in Japan
Introduced Lolium grasses are utilised in Japan for forage, turf and soil conservation. Many of these grasses have become naturalised in disturbed ecosystems. Neotyphodium endophytes in the tissues of grasses can increase host fitness by increasing tolerance to both biotic and abiotic stresses.

Vasoconstrictive Responses by the Carotid and Auricular Arteries in goats to Ergot Alkaloid Exposure
A fungal endophyte (Neotyphodium coenophialum) infects most plants of ‘Kentucky 31’ tall fescue (Lolium arundinaceum) and produces ergot alkaloids that cause persistent constriction of the vascular system in grazing livestock.
