Outline of Final Research Achievements |
Epichloae endophytes (Epichloe and asexual derivatives Neotyphodium species) systemically colonize the intercellular spaces of grasses to establish a symbiotic association. Colonization by epichloae endophytes confers various benefits on host plant growth and fitness to environmental conditions through the enhancement of plant resistance to a range of biotic and abiotic stresses, including drought, disease and herbivores. In this study, Epichloe and Neotyphodium isolates are used to investigate the role of parasexal recombination for the emergence of new isolates and evolution of endophytes. We successfully observed cell fusion, cell to cell transfer of nucleus and nuclear fusion of endophyte. We also isolated hybrid isolates which have variety of characteristics inherited from parents isolates.
