                      contribute to optimize water and nutrient uptake. Topsoil
                      exploitation vs. deep soil exploration represent two
                      contrasting ideotypes in relation to resource use. Our study
                      reveals how rooting patterns changed between wheat wild
                      progenitors and landraces in regard to these
                      ideotypes.MethodsRoot (partitioning, morphology,
                      distribution, elongation, anatomy) and shoot traits
                      (dry-matter, leaf area, assimilation) of durum landraces,
                      wild emmer and wild einkorn from Iran, Syria, Turkey and
                      Lebanon were phenotyped using the GrowScreen-Rhizo platform.
                      Distinctive rooting patterns were identified via principal
                      component analysis and relations with collection site
                      characteristics analyzed.ResultsShoot trait differentiation
                      was strongly driven by seed weight, leading to superior
                      early vigor of landraces. Wild progenitors formed
                      superficial root systems with a higher contribution of
                      lateral and early-emerging nodal axes to total root length.
                      Durum landraces had a root system dominated by seminal axes
                      allocated evenly over depth. Xylem anatomy was the trait
                      most affected by the environmental influence of the
                      collection site.ConclusionsThe durum landrace root system
                      approximated a deep soil exploration ideotype which would
                      optimize subsoil water uptake, while monococcum-type wild
                      einkorn was most similar to a topsoil exploiting strategy
                      with potential competitive advantages for subsistence in
                      natural vegetation.},
