DESCRIPTION:*Abstract* Arbuscular mycorrhizal (AM) symbiosis\, the partner
 ship between Glomeromycotina fungi and most plant species\, is a corne
 rstone of nearly every terrestrial ecosystem across all continents. AM sym
 biosis revolves around nutrient exchange\, with AM fungi providing soil mi
 neral nutrients to plants and receiving organic carbon in return. While mu
 ch has been elucidated about these nutrient transfers at the whole organis
 m scale\, little is known about their coordination at the actual sites of 
 nutrient exchange: the intracellular plant-fungal 'arbuscules'. Investigat
 ing arbuscule-scale processes has proven challenging due to their spatial 
 heterogeneity\, temporal dynamism\, and concealed location within plant ro
 ot cells underground. In this talk I will present the development of a cus
 tom\, non-invasive\, high- resolution imaging system for tracking arbuscul
 e dynamics over extended time periods. I will share the insights it has gi
 ven us into the coordination and regulation of phosphorus\, nitrogen and c
 arbon transfer during the interaction between rice and AM fungi\, and the 
 implications of this for our understanding of AM symbiosis. \n\n*Please no
