      abstract     = {Buckwheat (Fagopyrum esculentum Moench) is a pseudocereal
                      that was once a globally grown staple food. However, it was
                      replaced by higher yielding cereals such as wheat. In
                      Germany, it is nowadays only used as catch crop because of
                      its beneficial effects on soil health. With an increasing
                      interest in nutritious and gluten free products, buckwheat
                      consumption is on the rise, and buckwheat must currently be
                      imported. In the BMBF-funded interdisciplinary project
                      Buckwheat Improvement by Modern Technologies for the
                      Establishment of a Dual-Use Crop (BIMOTEC), we aim to
                      support buckwheat re-establishment in Germany by
                      additionally revealing its bioeconomic potential as
                      multi-purpose crop. Besides the improved production of
                      grains as food, the utilization of residual buckwheat
                      biomass is investigated, i.e. extraction of the secondary
                      metabolites like rutin from leaf biomass and seed hulls, as
                      well as bio-based platform compounds from stem biomass. An
                      extensive pre-breeding approach involving phenomics,
                      transcriptomics, and metabolomics combined with the
                      development of genome-editing technology will be a kickstart
                      for breeding of new local cultivars, while improved
                      agronomic models and industrial-scale metabolite extraction
                      protocols will support the production of buckwheat and
                      buckwheat-based products. As part of BIMOTEC, we initiated
                      the first large-scale image-based phenotyping of buckwheat
                      root traits. In high-throughput plant phenotyping
                      experiments using the novel phenotyping platform
                      GrowScreen-Rhizo III, we will quantify the genotypic
                      variation in root development of buckwheat in response to
                      drought. In a preliminary experiment, plants of the cultivar
                      ‘Devyatka’ were grown under control and drought
                      conditions, which were achieved by adjusting the soil water
                      potential to 0.2 MPa and 0.7 MPa, respectively. Here,
                      buckwheat revealed a widely branched taproot system with
                      many very fine roots. Based on the established protocol, we
                      will phenotype a panel of buckwheat genotypes under control
                      and drought conditions and combine our results with earlier
                      analyses of water-use strategies. In addition, we will
                      establish a root washing procedure to determine root traits
                      of buckwheat destructively. With this high throughput
                      phenotyping approach, we will provide new insights into
                      buckwheat drought tolerance and bring forward breeding of
                      local climate-resilient buckwheat cultivars.},
