Thesis Title
Hordeeae Epichloe endophytes and the formation of synthetic symbioses with cereal grasses
Read article at Massey Research Online:
Epichlo毛 fungi live in symbiosis with grass plants and benefit their hosts through increased resistance to a wide range of stresses, including drought and insect damage. Whilst Epichlo毛 are present in many wild grass species they are conspicuously absent from domesticated species, including important staple cereals such as wheat, barley and rye. Mr Simpson's research examined the possibility of infecting modern cereals with Epichlo毛 using a diverse range of Epichlo毛 strains collected in China. Inoculation studies demonstrated for the first time that domesticated cereals could be successfully infected with cultured Epichlo毛, with symbiosis outcomes ranging from fully compatible through to incompatible. Additionally, Mr Simpson showed that the genetics of the Epichlo毛 and the host cereal underpins this compatibility and that Epichlo毛 strain selection combined with host breeding could significantly improve the outcome of modern cereal-Epichlo毛 associations.
