      abstract     = {Compacted soils limit crop production and affect millions
                      of hectares of agricultural land globally. Plants vary in
                      tolerance to soil compaction and roots express various
                      plastic responses. Unfortunately, the importance of those
                      responses for crop yield and the implication in breeding are
                      practically unknown. Accordingly, to test whether the
                      plasticity of the root system architecture is associated
                      with the tolerance to soil compaction, we reviewed the
                      various root responses reported in the literature and
                      describe the consequences of soil compaction on the rooting
                      environment. Additionally, we carried out a set of
                      experiments to study the phenotypic diversity of shoot and
                      root plasticity in a collection of sorghum genotypes. For
                      that, plants were grown in a greenhouse for three to six
                      weeks in homo- and heterogeneous soil density gradients
                      (from 1.3 to 1.8 g cm-3). Finally, a simulation-based
                      research was conducted to study the plants functional
                      consequence of phenotypic response to soil compaction. As a
                      conclusion, sorghum genotypes can vary significantly in
                      terms of their response to soil compaction. Tolerant lines
                      are in general smaller sized genotypes which exhibit
                      plasticity to soil compaction for fine roots only.
                      Additionally, this tolerance is associated with the ability
                      to compensate the limited function of an impeded portion of
                      their root system, by growing less roots in those layers
                      where the strength is high and growing more roots in looser
                      zones. Although these responses are complex, root plasticity
                      can be targeted in breeding to increase the crop yield under
                      specific conditions such as low-input agronomic systems.},
