      abstract     = {Buckwheat is a globally grown pseudocereal, that was a
                      staple food in Germany until several decades ago, commonly
                      grown due to its short rotation time and low requirements.
                      However, breeding of buckwheat was neglected, resulting in
                      no improvement of low and unstable yield, which in turn led
                      to declined buckwheat cultivation for food production.
                      Nowadays, it is merely grown as catch crop due to its
                      beneficial effects on soil health. In recent years,
                      buckwheat gained rising interest as nutritious gluten-free
                      wheat-alternative, as grains are rich in proteins and
                      contain many 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 crop 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 and quercetin from buckwheat
                      for a subsequent biotechnological transformation into
                      compounds of higher value, thereby giving rise to the
                      establishment of novel value chains. Regional buckwheat
                      production is supported by use of agronomic models by
                      University of Hohenheim performs complementary field trials
                      and practical cultivation of buckwheat to validate agronomic
                      models for different conditions, that enable site-optimized
                      crop management to maximize grain yield and quality. 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.},
