                      studies on the influence of root temperature on plant
                      performance, growth and morphology. However, in all studies
                      root temperature was kept spatially uniform, which motivated
                      us to test whether a vertical gradient in soil temperature
                      affected development and biomass production. Roots of barley
                      seedlings were exposed to three uniform temperature
                      treatments (10, 15 or 20°C) or to a vertical gradient
                      (20-10°C from top to bottom). Substantial differences in
                      plant performance, biomass production and root architecture
                      occurred in the 30-day-old plants. Shoot and root biomass of
                      plants exposed to vertical temperature gradient increased by
                      144 respectively, $297\%,$ compared with plants grown at
                      uniform root temperature of 20°C. Additionally the root
                      system was concentrated in the upper 10cm of the soil
                      substrate $(98\%$ of total root biomass) in contrast to
                      plants grown at uniform soil temperature of 20°C $(86\%$ of
                      total root biomass). N and C concentrations in plant roots
                      grown in the gradient were significantly lower than under
                      uniform growth conditions. These results are important for
                      the transferability of 'normal' greenhouse experiments where
                      generally soil temperature is not controlled or monitored
                      and open a new path to better understand and experimentally
                      assess root-shoot interactions.},
