| Abstract/Contents: | "Epichloë and Neotyphodium endophytes are obligate biotrophs of cool-season grasses. These associations span a symbiotic continuum between mutualism and pathogenicity. One of the major factors contributing to the difference between the relative outcome of these interactions is expression of several symbiosis specific alkaloid classes. The phylogenetic relationships among these species, based on neutral characters, are among the best understood in the fungal kingdom. This study examines the evolutionary history of a secondary metabolite gene cluster associated with loline alkaloid expression. Analysis at two scales of evolution provides insights about both the origin and maintenance of this host-fitness enhancing trait. The data support our hypothesis that the trait likely evolved, at least in part, from gene duplications and recruitment from within an early ancestor of the endophytes. There is also evidence that the trait has been lost from more pathogenic endophyte species. Results will be discussed in the context of the major hypotheses governing the evolution of functionally related gene clusters." |
