abstract = {Belowground symptoms of sugar beet caused by the beet cyst
nematode (BCN) Heterodera schachtii include the development
of compensatory secondary roots and beet deformity, which,
thus far, could only be assessed by destructively removing
the entire root systems from the soil. Similarly, the
symptoms of Rhizoctonia crown and root rot (RCRR) caused by
infections of the soil-borne basidiomycete Rhizoctonia
solani require the same invasive approach for
identification. Here nuclear magnetic resonance imaging
(MRI) was used for the non-invasive detection of belowground
symptoms caused by BCN and/or RCRR on sugar beet. Excessive
lateral root development and beet deformation of plants
infected by BCN was obvious 28 days after inoculation (dai)
on MRI images when compared with non-infected plants.
Three-dimensional images recorded at 56 dai showed BCN cysts
attached to the roots in the soil. RCRR was visualized by a
lower intensity of the MRI signal at sites where rotting
occurred. The disease complex of both organisms together
resulted in RCRR development at the site of nematode
penetration. Damage analysis of sugar beet plants inoculated
with both pathogens indicated a synergistic relationship,
which may result from direct and indirect interactions.
Nuclear MRI of plants may provide valuable, new insight into
the development of pathogens infecting plants below- and
aboveground because of its non-destructive nature and the
sufficiently high spatial resolution of the method.},
