                      resource acquisition critically depends on
                      whole-plantarchitecture, encompassing both canopy and root
                      systems. In grafted grapevine, research has largely focused
                      onscion canopy structure, whereas root system architecture
                      – despite its key role in water and nutrient uptake
                      –remains underexplored. This study comprehensively
                      analysed whole-plant 3-D architecture during
                      vineyardestablishment, investigating how different rootstock
                      genotypes influence both root and shoot development.•
                      Methods Riesling scions were grafted onto three rootstock
                      genotypes (101-14, SO4 and 110R) and planted in avineyard
                      following a randomized complete block design. Whole-plant
                      excavations and high-resolution 3-Ddigitization were
                      performed to capture spatial data of root and shoot systems
                      from 96 vines at four time pointsover 2 years (3, 6, 15 and
                      18 months after planting). Key architectural parameters and
                      biomass partitioningwere quantified.• Key Results
                      Rootstock genotype strongly influenced whole-plant 3-D
                      architecture and biomass allocation.110R developed
                      significantly deeper, vertically oriented root systems (max
                      depth 180 cm) and exhibited higherroot-to-shoot biomass
                      ratios compared to SO4 and 101-14. Multivariate analysis
                      identified deep root length andoverall spatial root system
                      dimensions as primary discriminators among genotypes. Root
                      growth across allgenotypes was spatially biased along the
                      planting row, with limited extension into the inter-row
                      soil.• Conclusions Rootstock genotype is a key determinant
                      of whole-plant 3-D architecture and biomass partitioning.The
                      integration of above- and below-ground structural data
                      enables mechanistic interpretation of
                      rootstockmediatedtraits relevant to resource acquisition and
                      stress adaptation. Our comprehensive 3-D data set providesa
                      valuable foundation for functional–structural plant
                      modelling and offers practical insights for targetedbreeding
                      and management strategies to enhance climate resilience in
                      perennial crops.},
