 A greenhouse experiment was performed to investigate the influence of drought stress on the gene expression of *R. nigrum* cv Rosenthals Langtraubige. Stressed plants (A-C) that were not watered for 4 days were compared to control plants (D-F) with continuous irrigation. Both leaves and roots were sampled for RNA extraction.
