abstract = {Quantitative non-invasive measurement of structural and
functional development of plant organs allows for deep
phenotyping and dynamic investigation of plant performance
under stress. While this can be done straightforward for
leaves or stems other plant parts, such as seeds enclosed in
pods or roots and nodules hidden in soil are more difficult
to investigate. Their development however is critical for
yield and performance under stress and direct observations
in conjunction with genetic and metabolomics approaches may
hint on the underlying mechanisms. Here, we apply a set of
three non-invasive techniques for studying such
developmental processes: 1) Low field nuclear magnetic
resonance relaxometry with portable devices (pNMR) is used
to study dry matter and water content in pods over periods
of several weeks. 2) Magnetic Resonance Imaging (MRI) is
used to study the structural development of roots and
nodules in soil filled pots over several weeks. 3) Positron
Emission Tomography (PET) with the short-lived radiotracer
11C is used to monitor the partitioning of photoassimilates
and its dynamics among roots and nodules. We show the
application of all three techniques to pea and bean plants
grown in soil. We also discuss their potential to provide a
direct view on the effects of genotype or rhizobial strain
on plant performance under stress and on biological nitrogen
fixation.},
