abstract = {We studied the drought response of eight commercial hybrid
maize lines with contrasting drought sensitivity together
with the reference inbred line B73 using a non-invasive
platform for root and shoot phenotyping and a kinematics
approach to quantify cell level responses in the leaf.
Drought treatments strongly reduced leaf growth parameters
including projected leaf area, elongation rate, final length
and width of the fourth and fifth leaf. Physiological
measurements including water use efficiency, chlorophyll
fluorescence and photosynthesis were also significantly
affected. By performing a kinematic analysis, we show that
leaf growth reduction in response to drought is mainly due
to a decrease in cell division rate, whereas a marked
reduction in cell expansion rate is compensated by increased
duration of cell expansion. Detailed analysis of root growth
in rhizotrons under drought conditions revealed a strong
reduction in total root length as well as rooting depth and
width. This was reflected by corresponding decreases in
fresh and dry weight of the root system. We show that
phenotypic differences between lines differing in geographic
origin (African vs. European) and in drought tolerance under
field conditions can already be identified at the seedling
stage by measurements of total root length and shoot dry
weight of the plants. Moreover, we propose a list of
candidate traits that could potentially serve as traits for
future screening strategies.},
