| Abstract/Contents: | "Epichloë endophytes (Epichloë and Neotyphodium species) are important fungal symbionts that form mutualistic symbioses with cool season grasses. The asexual Neotyphodium species have been utilized in agriculture to enhance the persistence of grasses such as tall fescue and perennial ryegrass. These fungi are known to produce a range of bioprotective alkaloids, peramine, lolines, ergot alkaloids and lolitrems (indole-diterpenes) that provide anti-insect and anti-mammalian properties that protect their host. Of most interest in the agricultural setting are endophyte/grass associations that produce only the beneficial anti-insect alkaloids. Methodologies are well established to detect and quantify the presence of these alkaloids. More recently the genes required for the biosynthesis of the four bioprotective alkaloids have been cloned and characterized from a number of endophytes present in agriculturally important grasses. As found with other fungal secondary metabolite biosynthesis genes, the genes for three of the four alkaloids (ergot alkaloids, indole-diterpenes and lolines) are present in co-regulated gene clusters. This genomic organization enabled the identification of sets of genes that are likely to be involved in the biosynthesis of each alkaloid. The cloning and characterization of these alkaloid biosynthesis genes now provides an opportunity to understand the biochemical pathways by means of targeted mutagenesis and determine metabolite diversity across naturally occurring endophytes based on the presence and absence of genes." |
