Genetic Diversity in the Perennial Ryegrass Fungal Endophyte Neotyphodium lolii

2004
Expressed sequence tag (EST) data for the grass fungal endophyte species Neotyphodium lolii and N. coenophialum has been used to generate a comprehensive set of simple sequence repeat (SSR) markers for the genetic analysis of the grass-endophyte symbiosis. Initial analysis of reference isolates from the perennial ryegrass endophyte N.

Influence of Neotyphodium coenophialum on copper concentration in tall fescue.

Journal of Animal Science, 1998
Poor performance of livestock that graze tall fescue (Festuca arundinacea Schreb.) has been associated with the endophyte fungus Neotyphodium coenophialum [Morgan-Jones and Gams] Glenn, Bacon, and Hanlin). Recent evidence suggests lowered Cu status and a depression of Cu-related immune function in steers that graze endophyte-infected (E+) tall fescue ...

Monoclonal Antibodies for Detection of Neotyphodium coenophialum

Crop Science, 1997
A simple endophyte detection system is vital for breeding efforts designed to produce low alkaloid, endophyte‐infected tall rescue (Festuca arundinacea Schreb.) cultivars. The objectives of this research were to generate monoclonal antibodies specific to endophytes for immunochcmical detection purposes.

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.

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.

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.

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.

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.

Endophyte (Neotyphodium lolii) Effect on Parturition Date in Sheep

1997
Parturition in sheep has been found to be delayed on both endophyte (Neotyphodium lolu) infected ryegrass (Lolium perenne) pastures (Eerens et al., 1994) and endophyte (N. coenophialum) infected tall fescue (Festuca arundinacea) pastures (Bond et al., 1988). In both cases endophyte infection had no impact on birth weights of lambs, which contrasts with
