Evolution of the Flax Cell Wall Composition During Development and After Gravitropism by Synchrotron Fluorescence Imaging

Abstract

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.
