      abstract     = {The present study presents new insights into pH dynamics in
                      the rhizosphere of alpine pennycress (Noccaea caerulescens
                      (J. Presl $\&$ C. Presl) F.K. Mey), maize (Zea mays L.) and
                      ryegrass (Lolium perenne L.), when growing on three soils
                      contaminated by trace metals with initial pH values varying
                      from 5.6 to 7.4. The pH dynamics were recorded, using a
                      recently developed 2D imaging technique based on planar pH
                      optodes. This showed that alpine pennycress and ryegrass
                      alkalinized their rhizosphere by up to 1.7 and 1.5 pH units,
                      respectively, whereas maize acidified its rhizosphere by up
                      to -0.7 pH units. The alkalinization by the roots of alpine
                      pennycress and ryegrass was permanent and not restricted to
                      specific root zones, whereas the acidification along the
                      maize roots was restricted to the elongation zone and thus
                      only temporary. Calculations showed that such pH changes
                      should have noticeable effects on the solubility of the
                      trace metal in the rhizosphere, and therefore on their
                      uptake by the plants. As a result, it is suggested that
                      models for trace metal uptake should include precise
                      knowledge of rhizospheric pH conditions.},
