Neotyphodium in Native Populations of Arizona Fescue

1997
The discovery of the anti-herbivore properties of Neotyphodium endophytes, most of the available literature suggests that these endophytic fungi are plant defensive mutualists, and ecologists have readily extrapolated it to all endophyte-plant interactions (Breen 1994, Clay 1990).

New Neotyphodium endophyte species from the grass tribes Stipeae and Meliceae

Mycologia, 2007
Several species of Achnatherum (grass tribe Stipeae) and Melica (tribe Meliceae) typically are infected by nonpathogenic, seed-transmissible fungi with characteristics of Neotyphodium species (anamorphic Clavicipitaceae). Molecular phylogenetic studies clearly have distinguished the endophytes from Achnatherum inebrians (from Xinjiang Province, China),

Interactions of Neotyphodium gansuense, Achnatherum inebrians, and plant-pathogenic fungi

Mycological Research, 2007
Interactions of Neotyphodium gansuense, Achnatherum inebrians, and nine fungal pathogens were studied by tests of inhibition of four fungal pathogens by Neotyphodium endophytes in vitro and by inoculation of nine fungal pathogens on detached leaves of endophyte-infected (E+) and endophyte-free (E-) plants. Compared with the controls, most isolates of N.

Grasses and Neotyphodium endophytes: co-adaptation and adaptive breeding

Euphytica, 2006
Neotyphodium endophytes profoundly affect the biology of their host grasses, including the important forage species perennial ryegrass, tall fescue and meadow fescue. The endophytic association is finely balanced, involving adaptation in each associate. The evidence for co-adaptation is discussed.

Production of loline alkaloids by the grass endophyte, Neotyphodium uncinatum, in defined media

Phytochemistry, 2001
Lolines (saturated 1-aminopyrrolizidines with an oxygen bridge) are insecticidal alkaloids produced in symbioses of certain Epichloë (anamorph-Neotyphodium) species (fungal endophytes) with grasses, particularly of the genera Lolium and Festuca. Prior to the present study, it was unknown whether lolines were of plant or fungal origin.

Coregulated expression of loline alkaloid-biosynthesis genes in Neotyphodium uncinatum cultures

Fungal Genetics and Biology, 2009
Epichloë endophytes (holomorphic Epichloë spp. and anamorphic Neotyphodium spp.) are systemic, often heritable symbionts of cool-season grasses (subfamily Pooideae). Many epichloae provide protection to their hosts by producing anti-insect compounds.

Evolution of Epichloë/Neotyphodium Endophytes and Other Clavicipitalean Biotrophs

2001
There is good support for the hypothesis that the Epichloe/Neotyphodium endophytegrass association is a defensive mutualism. The endophytes may defend hosts from abiotic stresses such as drought and mineral toxicity and biotic stresses such as insects, mammal herbivores, and fungal diseases.

Neotyphodium endophytes may increase tolerance to Ni in tall fescue

European Journal of Soil Biology, 2014
Abstract Soil pollution with heavy metals is an important environmental problem which affects human and food health. Neotyphodium endophytes are a group of fungi which have their entire life cycle within the aerial parts of many cool-season grasses without any negative symptoms, and increase host tolerance to biotic and abiotic stresses.

Taxonomy ofNeotyphodiumendophytes of Chinese nativeRoegneriaplants

Mycologia, 2009
In this study we describe a new Neotyphodium species, Neotyphodium sinicum, found in natural symbiosis with asymptomatic Roegneria spp. (Elymus spp.) native to China. We investigated the host specificity, morphology, mating compatibility and molecular phylogenetic evidence for recognition of this new species. N.

Immunological Detection of the Neotyphodium-Like Endophyte of Annual Ryegrass

1997
Annual ryegrass (Lolium multiflorum) is sometimes infected with a Neotyphodium-like endophytic fungus (Latch et al. 1988). The significance of this little-studied endophyte is not thought to be great as it has not been associated with any livestock disorders, or with resistance to invertebrates, with the exception that Argentine stem weevil ...
