      abstract     = {The spatial and temporal dynamics of root water uptake in
                      nodal and seminal roots are poorly understood, especially in
                      relation to root system development and aging. Here we
                      non-destructively quantify 1) root water uptake and 2) root
                      length of nodal and seminal roots of barley in three
                      dimensions during 43 days of growth. We developed a
                      concentric split root system to hydraulically and physically
                      isolate the seminal and nodal root systems. Using magnetic
                      resonance imaging (MRI), roots were visualized, root length
                      was determined, and soil water depletion in both
                      compartments was measured. From 19 days after germination
                      and onwards, the nodal root system had greater water uptake
                      compared to the seminal root system due to both greater root
                      length and greater root conductivity. At 29 days after
                      germination onwards, the average age of the seminal and
                      nodal root systems was similar and no differences were
                      observed in water uptake per root length between seminal and
                      nodal root systems, indicating the importance of embryonic
                      root systems for seedling establishment and nodal root
                      systems in more mature plants. Since nodal roots perform the
                      majority of water uptake at 29 days after germination and
                      onwards, nodal root phenes merit consideration as a
                      selection target to improve water capture in barley and
                      possibly other crops.},
