abstract = {The spatial variation and underlying mechanisms of pattern
formation in the rhizosphere microbiome are not well
understood. We demonstrate that specific patterns in the
distribution of recently fixed carbon within the plant root
system influence the spatial organization of the rhizosphere
microbiota. Non-invasive analysis of carbon allocation in
the maize root system by 11C tracer-based positron emission
tomography combined with magnetic resonance imaging reveals
high spatial heterogeneity with highest 11C-signal
accumulations at root tips and differences between root
types. Strong correlations exist between root internal
carbon allocation and rhizodeposition as evident from 13CO2
labeling. These patterns are reflected in the bacterial,
fungal and protistan community structure in rhizosphere soil
with differences depending on root structure and related
spatial heterogeneities in carbon allocation. Especially the
active consumers of 13C-labeled rhizodeposits are responsive
to photosynthate distribution with differences in
13C-labeling according to their spatial localization within
the root system. Thus, root photosynthate allocation
supports distinct habitats in the plant root system and is a
key determinant of microbial food web development, evident
from 13C-labeling of diverse bacterial and protistan
predators, especially at root bases, resulting in
characteristic spatiotemporal patterns in the rhizosphere
microbiome.},
