                      streamsThe production of vegetables and fruits in
                      greenhouses leaves large amounts of residual plant biomass
                      behind, which represents a potential resource for the
                      extraction of valuable secondary metabolites such as
                      flavonoids. Various abiotic stresses induce selectively the
                      biosynthesis of different secondary metabolites in plants.
                      An application of targeted stress treatments in production
                      greenhouses after the last fruit harvest could therefore
                      increase the concentration of specific secondary metabolites
                      in residual plants. Thereby, residual horticultural plant
                      biomass is valorized, as it could be used for the extraction
                      of valuable metabolites. In order to identify stress
                      conditions that induce the accumulation of different
                      valuable secondary metabolites, we measured the content of
                      secondary metabolites of young tomato and bell pepper plants
                      subjected to various abiotic stress treatments. In the
                      projects InducTomE and TaReCa, we investigated the
                      inducibility of selected flavonoids which are of interest
                      due to their antioxidant potential and their bioactive
                      properties, and of the polyisoprenoid solanesol.
                      Additionally, metabolite screenings will be performed to
                      discover further target metabolites of high value and
                      industrial relevance. Thereby, we unfold the full potential
                      of the plant residuals as source of secondary metabolites.
                      To facilitate the implementation of stress treatment
                      protocols in greenhouses and to allow a quality control of
                      the valorized plant biomass, easy-to-use plant phenotyping
                      technologies for the quantification of plant stress
                      responses will be developed. In collaboration with project
                      partners working on gene expression and metabolite analyses,
                      transfer of induction protocols to commercial-like
                      greenhouses, efficient extraction technologies, and an
                      economic evaluation of the secondary metabolites extracted
                      from residual plant biomass, we will demonstrate a
                      proof-of-concept for the proposed valorization process. The
                      proposed valorization and utilization of plant residuals for
                      the extraction of valuable secondary metabolites will
                      contribute to an increased sustainability in horticultural
                      food production.},
