Maria Harrison studies the associations of arbuscular mycorrhizal (AM) fungi and plants. These mutualistic symbioses, which develop in plant roots, occur very broadly in terrestrial ecosystems and play a significant role in plant health. Research in Maria’s lab investigates the mechanisms underlying development and functioning of AM symbioses and asks how plant cells are reprogrammed to accommodate the fungal endosymbionts and how phosphate and carbon are transferred between the plant and fungus. Additionally, her research investigates the interactions of AM fungi with the soil microbiota and the roles of a conserved AM fungal microbiome.
