      abstract     = {Root system architecture (RSA), shoot architecture, and
                      shoot-to-root biomass allocation are critical for optimizing
                      crop water and nutrient capture and ultimately grain yield.
                      Nevertheless, only a few studies adequately dissected the
                      genetic basis of RSA and its relationship to shoot
                      development. Herein, we dissected at a high level of details
                      the RSA–shoot QTLome in a panel of 194 elite durum wheat
                      (Triticum turgidum ssp. durum Desf.) varieties from
                      worldwide adopting high-throughput phenotyping platform
                      (HTPP) and genome-wide association study (GWAS). Plants were
                      grown in controlled conditions up to the seventh leaf
                      appearance (late tillering) in the GROWSCREEN-Rhizo, a
                      rhizobox platform integrated with automated monochrome
                      camera for root imaging, which allowed us to phenotype the
                      panel for 35 shoot and root architectural traits, including
                      seminal, nodal, and lateral root traits, width and depth,
                      leaf area, leaf, and tiller number on a time-course base.
                      GWAS identified 180 quantitative trait loci (QTLs) (−log
                      p-value ≥ 4) grouped in 39 QTL clusters. Among those, 10,
                      11, and 10 QTL clusters were found for seminal, nodal, and
                      lateral root systems. Deep rooting, a key trait for
                      adaptation to water limiting conditions, was controlled by
                      three major QTLs on chromosomes 2A, 6A, and 7A. Haplotype
                      distribution revealed contrasting selection patterns between
                      the ICARDA rainfed and CIMMYT irrigated breeding programs,
                      respectively. These results provide valuable insights toward
                      a better understanding of the RSA QTLome and a more
                      effective deployment of beneficial root haplotypes to
                      enhance durum wheat yield in different environmental
                      conditions.},
