Flax lodging is an
issue of great interest for producers due to its economic impact. To better
understand its effects at the cell wall and stem scale, new knowledge regarding
the cell wall composition dynamics during cell wall development and after a 90°
tilt bending stress is reported. Deep-Ultra Violet fluorescence emission (DUV) dynamics
recorded at the Synchrotron SOLEIL-DISCO beamline by multichannel
autofluorescence imaging is reported for five cellular wall types of flax stems
after an artificially induced gravitropic reaction. Three flax growth
development stages, namely, the vegetative stage (VS), the fast growth (FG) and
the mature stage (MS), were selected in normal plants, referred to as the control
plants, or in gravitropic-induced response plants, referred to as 90° tilted
plants. <br>
