Abstract: Individual plants vary in their ability to respond to environmental changes. The plastic response of a plant enhances its ability to avoid environmental constraints, and hence supports growth and reproduction, and evolutionary and agricultural success. Due to the opaque nature of soil, a direct observation of belowground processes is not possible. Major progress in the analysis of belowground processes on individual plants has been made by the application of non-invasive imaging methods including Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET). MRI allows for repetitive measurements of roots growing in soil and facilitates quantification of root system architecture traits in 3D. PET, on the other hand, opens a door to analyze dynamic physiological processes in plants such as long-distance carbon transport in a repeatable manner. Combining MRI with PET enables monitoring of carbon tracer allocation into active sink structures such as nodules. Further, co-registration of MRI and PET allows for innovative and image-based sampling strategies of rhizosphere microorganisms, such as bacteria, fungi and protists.We are convinced that this approach will help revealing novel traits demanded in ecological studies or breeding programs for future crops.
