title = {{G}enotypic differences in early wheat seedling
establishment in natural soil investigated using
non-invasive 3{D} magnetic resonance imaging},

abstract = {Seed germination and seedling establishment are the first
important steps in a plant's growth cycle. We developed a
measurement pipeline to quantify the early stages of root
development in young seedlings in natural soil. We used
non-invasive magnetic resonance imaging (MRI), providing us
with 3D information about root structures. By growing up to
18 seedlings per pot (Ø=12.5cm, 10cm height) and by
focusing on early growth (up to 4 days after start of
germination), a much higher plant throughput compared to
traditional 3D root measurement protocols in soil was
achieved. Due to the high temporal resolution of the
acquired data sets (4 images per day), dynamic traits such
as shoot and root emergence time were obtained accurately.
We used this 'deep phenotyping' approach, with multiple
temporal and spatial layers of data, to investigate
genotypic differences using the 8 parent lines of the NIAB
MAGIC population. Clear genotypic differences in structural
(e.g. root angle, root lengths, and number) and temporal
(e.g. time of root emergence, shoot emergence) were
quantified. We identified different growth strategies among
the parent genotypes by correlating the temporal development
of traits. This new MRI method offers a promising tool for
high throughput root seedling screening in natural soil
environments, along with opportunities to discover new
traits based on dynamics of root and shoot development. This
work was financially supported by BASF.},
