000202330 520__ $$aThe development of a root system which is adequate for the respective growing conditions of a plant is critical for survival, performance and yield. Furthermore for “Root Crops” where the yield-relevant organ is developing belowground, the processes leading to amount and quality of the product at harvest also happen among the plants hidden half. The opaque nature of soil prevents direct observation and while a number of approaches for observing 2D root development such as rhizotrons have been applied successfully, roots naturally develop in interaction with the 3D soil environment and form complex 3D structures. Therefore the ability to deep-phenotype the 3D structure and function of roots and other belowground structures non-invasively yields a high potential for gaining new insights into root development, its regulation and responses to stress. Magnetic resonance imaging (MRI) is a technique that allows for visualization and quantification of root system architecture traits in soil such as root length and mass but also of internal structures of belowground storage organs. Positron emission tomography (PET) using short-lived radiotracer 11CO2 provides additional imaging of the photoassimilate distribution and flow characteristics can be extracted with a model-based analysis. We show here application of both techniques for visualization and quantification of root system architecture, anatomy and photoassimilate allocation.
