Lay summary
The objective of the research proposal is to investigate the significance of hybrid Neotyphodium endophytes (Clavicipitaceae Ascomycota) for the ecological fitness of their host plants in different environments. As study system we will use the woodland grass Hordelymus europaeus that is known to be host of hybrid and non-hybrid endophytes. The specific research questions are:1) What is the frequency and pattern of distribution of hybrid and non-hybrid endophytes over a large geographic area along a gradient from north to south, and does this correlate with environmenal conditions?2) What are the consequences of hybrid and non-hybrid endophyte infection for the ecological fitness of host plants?3) What is the competitive outcome of hybrid and non-hybrid endophytes when inoculated simultaneously into host plants?Endophytes are of considerable economic importance due to their implication in toxicosis of livestock and their ability to increase stress tolerance of forage and turf grasses.
