abstract = {Development of arbuscular mycorrhizal fungal colonization
of roots and the surrounding soil is the central process of
mycorrhizal symbiosis, important for ecosystem functioning
and commercial inoculum applications. To improve mechanistic
understanding of this highly spatially and temporarily
dynamic process, we developed a three-dimensional model
taking into account growth of the roots and hyphae. It is
for the first time that infection within the root system is
simulated dynamically and in a spatially resolved way.
Comparison between data measured in a calibration experiment
and simulated results showed a good fit. Our simulations
showed that the position of the fungal inoculum affects the
sensitivity of hyphal growth parameters. Variation in speed
of secondary infection and hyphal lifetime had a different
effect on root infection and hyphal length, respectively,
depending on whether the inoculum was concentrated or
dispersed. For other parameters (branching rate, distance
between entry points), the relative effect was the same
independent of inoculum placement. The model also indicated
that maximum root colonization levels well below $100\%,$
often observed experimentally, may be a result of
differential spread of roots and hyphae, besides intrinsic
plant control, particularly upon localized placement of
inoculum and slow secondary infection.},
