TL;DR: Investigating three contrasting root/shoot systems growing in sand or soil, with respect to their structures, transport routes and the translocation dynamics of recently fixed photoassimilates labelled with the short-lived radioactive carbon isotope opens the door for non-invasive analysis of plant structures and transport processes that may change in response to genomic, developmental or environmental challenges.

TL;DR: The value of combining different phenotyping technologies that analyse processes at different spatial and temporal scales is demonstrated and novel routes may be opened up for improved plant breeding as well as for mechanistic understanding of root structure and function.

TL;DR: Both techniques performed equally well for pots with small diameters which are best suited to monitor root development of seedlings, but for larger pot diameters, MRI delivered higher fractions of the root systems than CT, most likely because of the strong root-to-soil contrast achievable by MRI.

TL;DR: A plant root imaging and analysis pipeline using MRI together with an advanced image visualization and analysis software toolbox named NMRooting is presented, showing that roots down to a diameter range between 200 μm and 300 μm can be quantitatively measured.

TL;DR: The data demonstrate continuous synthesis and degradation of carotenes and Chl a in photosynthesizing leaves and indicate distinct acclimatory responses of their turnover to changing irradiance.
