abstract = {In recent years the study of root phenotypic plasticity in
response to sub-optimal environmental factors and the
genetic control of these responses have received renewed
attention. As a path to increased productivity, in
particular for low fertility soils, several applied research
projects worldwide target the improvement of crop root
traits both in plant breeding and biotechnology contexts. To
assist these tasks and address the challenge of optimizing
root growth and architecture for enhanced mineral resource
use, the development of realistic simulation models is of
great importance. We review this research field from a
modeling perspective focusing particularly on nutrient
acquisition strategies for crop production on low nitrogen
and low phosphorous soils. Soil heterogeneity and the
dynamics of nutrient availability in the soil pose a
challenging environment in which plants have to forage
efficiently for nutrients in order to maintain their
internal nutrient homeostasis throughout their life cycle.
Mathematical models assist in understanding plant growth
strategies and associated root phenes that have potential to
be tested and introduced in physiological breeding programs.
At the same time, we stress that it is necessary to
carefully consider model assumptions and development from a
whole plant-resource allocation perspective and to introduce
or refine modules simulating explicitly root growth and
architecture dynamics through ontogeny with reference to key
factors that constrain root growth. In this view it is
important to understand negative feedbacks such as
plant–plant competition. We conclude by briefly touching
on available and developing technologies for quantitative
root phenotyping from lab to field, from quantification of
partial root profiles in the field to 3D reconstruction of
whole root systems. Finally, we discuss how these approaches
can and should be tightly linked to modeling to explore the
root phenome.},
