A defensive role for several of the major alkaloids of Neotyphodium spp. endophytes in forage grasses has been confirmed in genetic experiments. However, many aspects of the activity of endophyte-infected grasses towards herbivores remain unaccounted for, suggesting there are further anti-herbivore factors yet to be uncovered. The development of metabolomics has provided new tools for the discovery of novel metabolites without preconceptions of the likely chemical structural class. Prospects for the application of new methods from metabolomics to further elucidate the defensive chemistry of associations of Neotyphodium spp. endophytes with their grass hosts are reviewed. Keywords: Neotyphodium, Epichloë, defensive chemistry, invertebrate, vertebrate, gene deletion
