Arbuscular mycorrhizal (AM) symbiosis is widespread among land plants. In contrast to pathogens, the penetration of AM fungi within plant root tissues does not trigger extended immune responses. Evidences suggest that similar to pathogens symbiotic microorganisms have evolved effectors to manipulate the host and allow the symbiosis to occur. So far only one effector from R. irregularis has been identified and characterized. The aim of my research is to identify new symbiotic effectors involved in the establishment of the symbiosis between R. irregularis and Nicotiana benthamiana. Based on the secretome of R. irregularis, 24 proteins have been selected as potential effectors. By using the knowledge acquired from studies on pathogen effectors, several experiments will be performed to narrow down the candidate list and identify true effector proteins.
