| Abstract/Contents: | "Neotyphodium fungal species form endophytic symbioses with agronomically important pasture grasses. Tall fescue (Lolium arundinanceum [Schreb.] Darbysh syn. Festuca arundinacea Schreb.) is generally reported to associate with the endophyte Neotyphodium coenophialum. Both beneficial and detrimental agronomic properties result from the association, including improved tolerance to water and nutrient stress and resistance to invertebrate pests. Invertebrate resistance is provided by specific metabolites produced by the endophyte, in particular loline alkaloids and peramine. Other metabolites produced by the endophyte, such as ergot alkaloids, are toxic to grazing animals and reduce herbivore feeding. Genetically novel endophyte strains with favourable alkaloid proles have been identified in a study of global genetic diversity using expressed sequence tags (EST)-derived simple sequence repeats (SSR) markers combined with metabolic profiling. Novel endophytes have been isolated for inoculation into an isogenic host plant genotype panel selected from elite tall fescue germplasm to assess endophyte compatibility, and vegetative stability, with the host plant genotype. Nine out of 10 novel endophytes strains were successfully inoculated into four host genotypes representing a broad range of tall fescue cultivars. Following inoculation, in-depth characterisation of the designer symbiota (i.e. endophyte-host associations) can be performed independent of effects due to host genotype variation." |
