      abstract     = {Buckwheat (Fagopyrum esculentum) is a globally grown
                      pseudocereal, that had been a staple food in Germany until
                      several decades ago, commonly grown due to its short growing
                      period and low input requirements. However, due to low
                      yields compared to cereal crops, it is nowadays hardly
                      cultivated in Germany, and merely used as catch crop due to
                      its beneficial effects on soil health. Consequently,
                      breeding of buckwheat was neglected, resulting in no
                      improvement of low and unstable yields. In recent years,
                      buckwheat gained rising interest as nutritious gluten-free
                      wheat-alternative, as grains are rich in proteins and
                      contain health stimulating secondary metabolites. These
                      phytochemicals, e.g. rutin and quercetin, are also present
                      in high levels in leaves and hulls. In Asia, they are used
                      for teas and the extraction of rutin for pharmaceutical
                      purposes. With longer growing seasons in Germany due to
                      global warming, buckwheat could be cultivated as second crop
                      in a double cropping system, which increases
                      agrobiodiversity and climate-resilience of agricultural food
                      production and generates additional income for farmers. As
                      buckwheat also thrives on marginal sites, its cultivation
                      could also contribute to the recultivation of opencast
                      mining areas.In BIMOTEC, we evaluate the potential of
                      buckwheat as dual-use crop to leverage both grains for food
                      production and residual biomass for the extraction of
                      biobased compounds, such as valuable phytochemicals from
                      leaves and hulls and lignocellulose from stems. Breeding of
                      dual-use plants offers great potential to establish
                      innovative bio-based value chains. To support buckwheat
                      production in Germany and develop climate-resistant local
                      buckwheat varieties, academic and industrial partners
                      collaborate in an interdisciplinary approach. At
                      Forschungszentrum Jülich GmbH, Institute for Plant Sciences
                      (IBG-2), the genotypic variation of root and shoot growth of
                      buckwheat is characterized using high throughput plant
                      phenotyping. Analysis of stress responses to drought and
                      nutrient deficiency support the identification of favorable
                      phenotypic traits and selection of resource-efficient
                      buckwheat cultivars for breeding. Bioinformatic gene
                      expression studies and rutin content analyses by the
                      Institute for Bioinformatics (IBG-4) enable the selection of
                      promising genotypes for the extraction of valuable
                      phytochemicals and identification of marker genes for
                      breeding of climate-resilient varieties. Fraunhofer IME
                      performs in-depth metabolite profiling for the discovery of
                      further valuable secondary metabolites, aiming to exploit
                      results for industrial applications to increase the economic
                      viability. The suitability of buckwheat residual biomass for
                      the extraction of valuable phytochemicals is investigated by
                      the industrial partner Phytowelt, who will scale up
                      extraction processes for rutin from buckwheat for a
                      subsequent biotechnological transformation into compounds of
                      higher value, thereby giving rise to the establishment of
                      novel value chains. University of Hohenheim performs
                      complementary field trials and on-farm cultivation of
                      buckwheat to validate process-oriented crop models for
                      different conditions. Crop models will facilitate
                      site-optimized crop management to maximize grain yield and
                      quality and thereby support the regional buckwheat
                      production. At IPK Gatersleben, genome editing technologies
                      for the biotechnological improvement of buckwheat are being
                      developed to adapt agronomically important traits, laying
                      the foundation for future modern breeding
                      initiatives.BIMOTEC’s interdisciplinary consortium
                      contributes to re-establish the regional production of
                      buckwheat and supports German plant breeders to resume their
                      work on this neglected crop. The development of buckwheat as
                      a dual-use crop for the production of bio-based compounds
                      from green biomass supports the development of innovative
                      value chains and contributes to the development of a
                      bio-based industry in Germany.},
