Interpretive Summary: A number of updates on research projects conducted within Tennessee concerning tall fescue (Lolium arundinacium) and its symbiotic endophyte (Neotyphodium coenophialum) were presented at the annual SERA-IEG 8 workshop including one with Forage-Animal Production Research Unit scientist collaborations. The project with FAPRU scientific involvement had the goal of defining a genetic marker for resistance to fescue toxicosis in beef cattle. Initial genetic screens of a subset of cattle on endophyte-infected tall fescue indicated that a specific SNP residing in the genome of cattle appeared to be correlated with rough hair coats (a sign of fescue toxicosis. Further, research is required before full validation of this SNP is accomplished. For additional detail, the entire meeting report can be viewed at the following website http://animalscience.ag.utk.edu/SERA-IEG8/default.htm
