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.},
