      abstract     = {Plant–soil interactions can strongly influence root
                      growth in plants. There is now increasing evidence that
                      root–root interactions can also influence root growth,
                      affecting architecture and root traits such as lateral root
                      formation. Both when species grow alone or in interaction
                      with others, root systems are in turn affected by as well as
                      affect rhizosphere pH. Changes in soil pH have knock-on
                      effects on nutrient availability. A limitation until
                      recently has been the inability to assign species identity
                      to different roots in soil. Combining the planar optode
                      technique with fluorescent plants enables us to distinguish
                      between plant species grown in natural soil and in parallel
                      study pH dynamics in a non-invasive way at the same region
                      of interest (ROI). We measured pH in the rhizosphere of
                      maize and bean in rhizotrons in a climate chamber, with ROIs
                      on roots in proximity to the roots of the other species as
                      well as not-close to the other species. We found clear
                      dynamic changes of pH over time and differences between the
                      two species in rhizosphere acidification. Interestingly,
                      when roots of the two species were interacting, the degree
                      of acidification or alkalization compared to bulk soil was
                      less strong then when roots were not growing in the vicinity
                      of the other species. This cutting-edge approach can help
                      provide a better understanding of plant–plant and
                      plant–soil interactions.},
