      abstract     = {Drought is a major factor limiting plant productivity
                      worldwide. Certain wild plant species have developed
                      specialized mechanisms for avoiding or tolerating drought
                      that are not present in model plants or domesticated crops.
                      Further, the relation of rhizosphere microbiota in the
                      adaptation to drought stress responses is not resolved in
                      wild plant species. Common evening-primrose (Oenothera
                      biennis) is used for its high seed content of the triple
                      unsaturated fatty acid gamma-linolenic acid, which is of
                      great interest to the cosmetic, pharmaceutical and
                      surfactant industries. Additionally, this plant species also
                      thrives on rocky and sandy soils, such as dry waste ground,
                      roadsides, and railway cuttings. Hence, O. biennis is an
                      excellent model to investigate the influence of drought
                      conditions on root morphology and rhizosphere microbiome
                      assembly to gain more insight into drought tolerance
                      adaptation. A drought stress experiment was performed using
                      the automated GrowScreen-Rhizo III root phenotyping platform
                      at Forschungszentrum Jülich for four weeks. The plants were
                      grown in soil-filled rhizotrons with one transparent plate
                      which allowed non-invasive measurements of root development
                      over time. The experiment included three genotypes of O.
                      biennis with strong responses to the applied stress on both
                      shoot biomass level and root morphology. . Drought stress
                      strongly reduced root growth of all genotypes and affected
                      root system architectural traits, such as root system depth
                      and width. Detailed analysis of the responses on root
                      morphological traits of different genotypes is ongoing. In
                      parallel, rhizosphere microbiota was targeted in the
                      analysis. The results and possible implications of these
                      studies on the drought stress response of a wild plant
                      species are presented here.},
