      abstract     = {Differential growth processes in root and shoot growth
                      zones are governed by the transport kinetics of auxin and
                      other plant hormones. While gene expression and protein
                      localization of hormone transport facilitators are currently
                      being unraveled using state-of-the-art techniques of live
                      cell imaging, the quantitative analysis of growth reactions
                      is lagging behind because of a lack of suitable methods. A
                      noninvasive technique, based on digital image sequence
                      processing, for visualizing and quantifying highly resolved
                      spatio-temporal root growth processes was applied in the
                      model plant Arabidopsis thaliana and was adapted to provide
                      precise information on differential curvature production
                      activity within the root growth zone. Comparison of root
                      gravitropic curvature kinetics in wild-type and mutant
                      plants altered in a facilitator for auxin translocation
                      allowed the determination of differences in the location and
                      in the temporal response of curvature along the growth zone
                      between the investigated plant lines. The findings of the
                      quantitative growth analysis performed here confirm the
                      proposed action of the investigated transport facilitator.
                      The procedure developed here for the investigation of
                      differential growth processes is a valuable tool for
                      characterizing the phenomenology of a wide range of shoot
                      and root growth movements and hence facilitates elucidation
                      of their molecular characterization.},
