      abstract     = {Due in part to recent progress in root genetics and
                      genomics, increasing attention is being devoted to root
                      system architecture (RSA) for the improvement of drought
                      tolerance. The focus is generally set on deep roots,
                      expected to improve access to soil water resources during
                      water deficit episodes. Surprisingly, our quantitative
                      understanding of the role of RSA in the uptake of soil water
                      remains extremely limited, which is mainly due to the
                      inherent complexity of the soil-plant continuum. Evidently,
                      there is a need for plant biologists and hydrologists to
                      develop together their understanding of water movement in
                      the soil-plant system. Using recent quantitative models
                      coupling the hydraulic behaviour of soil and roots in an
                      explicit 3D framework, this paper illustrates that the
                      contribution of RSA to root water uptake is hardly separable
                      from the hydraulic properties of the roots and of the soil.
                      It is also argued that the traditional view that either the
                      plant or the soil should be dominating the patterns of water
                      extraction is not generally appropriate for crops growing
                      with a sub-optimal water supply. Hopefully, in silico
                      experiments using this type of model will help explore how
                      water fluxes driven by soil and plant processes affect soil
                      water availability and uptake throughout a growth cycle and
                      will embed the study of RSA within the domains of root
                      hydraulic architecture and sub-surface hydrology.},
