      abstract     = {Damage caused by root-knot nematodes (RKNs) is highly
                      remarkable for below-ground plant parts especially at the
                      early stages of infection. Gall development at the roots is
                      the primary symptom observed during RKN parasitism. The
                      opaque nature of soils does not allow direct in-situ
                      quantification of the dynamic response of roots to RKN
                      infection. Accessing and quantifying such effects has been
                      mostly based on destructive methods. In this current study,
                      magnetic resonance imaging (MRI) was used to non-invasively
                      observe the dynamic response of carrot roots infected with
                      RKNs in soil-filled microcosms. We subjected RKN infected
                      plants to MRI plant phenotyping platform at a 7-day interval
                      until a stage of 49 days post inoculation (dpi). Acquired
                      images were analyzed using the MeVisLab application
                      software. Analysis of 3 dimensional images showed the
                      initiation of gall development at 28 dpi and allowed the
                      tempo-spatial analysis of gall development on roots until 49
                      dpi. Gall development was prominent on secondary roots and
                      mostly within the uppermost 0.5 to 5 cm part of roots.
                      Classification of gall sizes revealed that MRI allowed the
                      detection of galls above 0.6 mm width. Further, the presence
                      of RKN reduced taproot volume by $20\%.$ These findings
                      indicate the utility and capacity of MRI as a potent
                      non-invasive approach for monitoring and quantifying early
                      responses of below-ground plant parts to RKNs infection.},
