abstract = {Hyperaccumulating plants possess complex traits, allowing
them to thrive in soils with high concentrations of trace
metal elements (TME). Accordingly, their TME hypertolerance
and hyperaccumulation capacities have been intensely studied
from physiological, evolutionary, and ecological
perspectives. Little is known, however, about their root
system development in TME enriched vs natural soils. We
assessed temporal and quantitative changes in root systems
of the model species Arabidopsis halleri, using a novel
combination of root phenotyping in rhizoboxes and
multitemporal digital imaging. We continuously monitored
root growth of two non-metallicolous and two metallicolous
populations in different substrate treatments, including
homogeneous and horizontal layer applications of
metalliferous and non-metalliferous soils. Non-metallicolous
plants on non-metalliferous soils produced deep-reaching and
wide roots, whereas metallicolous plants on metalliferous
soil had smaller roots. This pattern was reversed when
transplanting seedlings to foreign substrates, indicating
that environment rather than ecotype determines root growth
in A. halleri. Dampened root development in metalliferous
and favored root proliferation in non-metalliferous soils
indicate cost of tolerance and TME foraging, respectively.
Importantly, root propagation into metalliferous soil was
strongly promoted by a non-metalliferous “capping” layer
that facilitated initial plant development. Hence, growing
on non-polluted substrate in the early stage provides plants
with a robust and optimal root system that facilitates
seedling establishment and subsequent development under TME
enriched conditions. These findings improve our
understanding of plant performance in metalliferous
environments and can help refine management practices for
the sustainable reclamation of degraded lands.},
