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.},
