A symbiosis expressed non‐ribosomal peptide synthetase from a mutualistic fungal endophyte of perennial ryegrass confers protection to the symbiotum from insect herbivory
While much is known about the biosynthesis of secondary metabolites by filamentous fungi their biological role is often less clear. The assumption is these pathways have adaptive value to theExpand
The exploitation of epichloae endophytes for agricultural benefit
Epichloae endophytes of family Clavicipitaceae (comprising genera Epichloë and Neotyphodium) are fungal symbionts of Pooideae grasses. The associations formed, range from mutually beneficial toExpand
Ryegrass endophyte: a New Zealand Grassland success story
The discovery in 1981 that ryegrass endophyte is responsible for ryegrass staggers has required a total revision of our understanding of ryegrassbased pastures. The effects on grazing livestock rangeExpand
A review of the Neotyphodium lolii / Lolium perenne symbiosis and its associated effects on animal and plant health, with particular emphasis on ryegrass staggers
Abstract Ryegrass staggers is a seasonal mycotoxicosis of grazing livestock characterised by tremors, in coordination and a staggering gait almost unaccompanied by physical lesions. Deaths occur onlyExpand
Importance of host plant species, Neotyphodium endophyte isolate, and alkaloids on feeding by Spodoptera frugiperda (Lepidoptera: Noctuidae) larvae.
Three grass host species--tall fescue, Festuca arundinacea Schreber; meadow fescue, Festuca pratensis Hudson; and perennial ryegrass, Lolium perenne L.--each infected with a number of differentExpand
Impact of novel endophytes in perennial ryegrass on herbage production and insect pests from pastures under dairy cow grazing in northern New Zealand
Perennial ryegrass (Lolium perenne L.) infected with a novel endophyte (AR37 or AR1), Wild-type endophyte or no endophyte (Nil) was sown with white clover (Trifolium repens L.) in autumn 2005. TheExpand
Endophytes improve ryegrass persistence by controlling insects
Fungal endophytes reduce populations and damage by several different insect pests which alone or in combination with each other can reduce ryegrass persistence. AR1, AR37, the Standard endophytes andExpand
Agronomic performance of AR 37-infected ryegrass in northern New Zealand
The agronomic merits of a perennial ryegrass (Lolium perenne) cultivar infected with a new endophyte (Neotyphodium lolii), AR37, were compared with the same cultivar infected with currently availableExpand
Endophyte effects on major insect pests in Waikato dairy pasture.
A paddock-scale field trial comparing pastures of perennial ryegrass without endophyte (Nil) or infected with the selected endophytes AR1, AR37 or the standard endophyte (SE) sown with clover wasExpand
