Journal ArticleDOI
Fungal endophyte-infected grasses: Alkaloid accumulation and aphid response.
Malcolm R. Siegel,G. C. M. Latch,Lowell P. Bush,F.F. Fannin,Daryl D. Rowan,B. A. Tapper,Charles W. Bacon,M. C. Johnson +7 more
TL;DR: The occurrence of the alkaloidsN-formyl andN-acetyl loline, peramine, lolitrem B, and ergovaline and the response of aphids to plants containing these compounds were determined in species and cultivars ofFestuca,Lolium, and other grass genera infected with fungal endophytes.
Journal ArticleDOI
A symbiosis expressed non‐ribosomal peptide synthetase from a mutualistic fungal endophyte of perennial ryegrass confers protection to the symbiotum from insect herbivory
TL;DR: The first genetic evidence that the fungal produced secondary metabolite, peramine, protects a host plant from insect herbivory is provided, confirming that peramine is the E.’festucae metabolite responsible for ASW feeding deterrent activity.
Journal ArticleDOI
The exploitation of epichloae endophytes for agricultural benefit
Linda J. Johnson,Anouck C. M. de Bonth,Lyn R. Briggs,John R. Caradus,Sarah C. Finch,Damien J. Fleetwood,LR Fletcher,David E. Hume,Richard D. Johnson,Alison J. Popay,B. A. Tapper,Wayne R. Simpson,Christine R. Voisey,Stuart D. Card +13 more
TL;DR: This review weaves together the different strands of multidisciplinary research aimed at ultimately exploiting epichloae endophytes for increased pasture performance.
Journal ArticleDOI
Taxonomy of Acremonium endophytes of tall fescue (Festuca arundinacea), meadow fescue (F. pratensis) and perennial ryegrass (Lolium perenne)
TL;DR: Alkaloid production in the natural host grass-Acremonium associations proved a useful taxonomic criterion, with the profile of alkaloids being consistent in the host plants for all isolate within a single isozyme phenotype and for most isolates within a taxonomic grouping.
Journal ArticleDOI
Molecular cloning and genetic analysis of a symbiosis-expressed gene cluster for lolitrem biosynthesis from a mutualistic endophyte of perennial ryegrass
Carolyn A. Young,Michelle K. Bryant,M.J. Christensen,B. A. Tapper,Gregory T. Bryan,Barry Scott +5 more
TL;DR: Lolitrems are potent tremorgenic mycotoxins that are synthesised by clavicipitaceous fungal endophytes of the Epichloë/Neotyphodium group in association with grasses that confer major ecological benefits on the grass–endophyte symbiotum.
